+			DDC.HOWTO
+
+  This file describes how to add DDC support to a chipset driver.
+
+1) DDC INITIALIZATION
+
+   When implementing DDC in the driver one has the choice between
+   DDC1 and DDC2. 
+   DDC1 data is continuously transmitted by a DDC1 capable display 
+   device. The data is send serially over a data line; the Vsync 
+   signal serves as clock. Only one EDID 1.x data block can be 
+   transmitted using DDC1. Since transmission of an EDID1 block 
+   using a regular Vsync frequency would take up several seconds 
+   the driver can increase the Vsync frequency to up to 25 kHz as 
+   soon as it detects DDC1 activity on the data line.
+   DDC2 data is transmitted using the I2C protocol. This requires
+   an additional clock line. DDC2 is capable of transmitting EDID1
+   and EDID2 block as well as a VDIF block on display devices that 
+   support these.  
+   Display devices switch into the DDC2 mode as soon as they detect
+   activity on the DDC clock line. Once the are in DDC2 mode they
+   stop transmitting DDC1 signals until the next power cycle.
+
+   Some graphics chipset configurations which are not capable of
+   DDC2 might still be able to read DDC1 data. Where available
+   DDC2 it is preferable. 
+	
+   All relevant prototypes and defines are in xf86DDC.h.
+   DDC2 additionally requires I2C support. The I2C prototypes
+   are in xf86i2c.h.
+
+   DDC1 Support:
+
+     The driver has to provide a read function which waits for the
+     end of the next Vsync signal and reads in and returns the status
+     of the DDC line:
+
+     unsigned int XXX_ddc1Read(ScrnInfoPtr pScrn)
+     
+     Additionally a function is required to increase the Vsync
+     frequency to max. 25 kHz. 
+ 
+     void XXX_ddc1SetSpeed(ScrnInfoPtr pScrn, xf86ddcSpeed speed)
+ 
+     If the speed argument is DDC_FAST the function should increase
+     the Vsync frequency on DDC_SLOW it should restore the original
+     value. For convenience a generic ddc1SetSpeed() function is provided
+     in the vga module for VGA-like chipsets.     
+	
+     void vgaHWddc1SetSpeed(ScrnInfoPtr pScrn, sf86ddcSpeed speed).
+
+     To read out the DDC1 data the driver should call 
+
+     xf86MonPtr xf86DoEDID_DDC1(int scrnIndex, 
+                              void (*DDC1SetSpeed)(ScrnInfoPtr, xf86ddcSpeed),
+                              unsigned int (*DDC1Read)(ScrnInfoPtr))
+ 
+     in PreInit(). DDC1SetSpeed is a pointer to the SetSpeed()
+     function, DDC1Read has to point to the DDC1 read function.
+     The function will return a pointer to the xf86Monitor structure
+     which contains all information retrieved by DDC.
+     NULL will be returned on failure.
+
+   DDC2 Support
+ 
+     To read out DDC2 information I2C has to be initialized first.
+     (See documentation for the i2c module). 
+     The function 
+     
+     xf86MonPtr xf86DoEDID_DDC2(int scrnIndex, I2CBusPtr pBus)
+
+     is provided to read out and process DDC2 data. A pointer
+     to the I2CBusRec of the appropriate I2C Bus has to be passed
+     as the second argument.
+     The function will return a pointer to the xf86Monitor structure
+     which contains all information retrieved by DDC.
+     NULL will be returned on failure.
+
+   Printing monitor parameters   
+
+     To print out the information contained in the xf86Monitor
+     structure the function 
+
+     xf86MonPtr xf86PrintEDID(xf86MonPtr monitor)
+ 
+     is provided.
+
+    Further processing of the xf86Monitor structure is not yet 
+    implemented. However, it is planned to use the information
+    about video modes, gamma values etc.
+    Therefore it is strongly recommended to read out DDC data
+    before any video mode processing is done.
+
+

+		    Multi-monitor Mode Setting APIs
+	           Keith Packard, <keithp@keithp.com
+		   	   6 March 2007
+
+1. Introduction
+
+This document describes a set of mode setting APIs added in X server version
+1.3 that support multiple monitors per card. These interfaces expose the
+underlying hardware CRTC and output concepts to the xf86 DDX layer so that
+the implementation of initial server setup and mode changes through
+extensions can be shared across drivers. In addition, these new interfaces
+support a new configuration mechanism as well which allows each monitor to
+be customized separately providing a consistent cross-driver configuration
+mechanism that supports the full range of output features.
+
+All of the code implementing this interface can be found in hw/xfree86/modes
+in the X server sources.
+
+2. Overview
+
+This document describes both the driver API and the configuration data
+placed in xorg.conf; these are entirely separate as the driver has no
+interaction with the configuration information at all. Much of the structure
+here is cloned from the RandR extension version 1.2 additions which deal
+with the same kinds of information.
+
+2.1 API overview
+
+The mode setting API is expressed through two new driver-visible objects,
+the 'CRTC' (xf86CrtcRec) and the 'Output' (xf86OutputRec). A CRTC refers to
+hardware within the video system that can scan a subset of the framebuffer
+and generate a video signal. An Output receives that signal and transmits it
+to a monitor, projector or other device.
+
+The xf86CrtcRec and xf86OutputRec contain a small amount of state data
+related to the object along with a pointer to a set of functions provided by
+the driver that manipulate the object in fairly simple ways.
+
+To emulate older behaviour, one of the outputs is picked as the 'compat'
+output; this output changes over time as outputs are detected and used, the
+goal is to always have one 'special' output which is used for operations
+which need a single defined monitor (like XFree86-VidModeExtension mode
+setting, RandR 1.1 mode setting, DDC property setting, etc.).
+
+2.1.1 Output overview 
+
+As outputs are connected to monitors, they hold a list of modes supported by
+the monitor. If the monitor and output support DDC, then the list of modes
+generally comes from the EDID data in the monitor. Otherwise, the server
+uses the standard VESA modes, pruned by monitor timing. If the configuration
+file doesn't contain monitor timing data, the server uses default timing
+information which supports 640x480, 800x600 and 1024x768 all with a 60Hz
+refresh rate.
+
+As hardware often limits possible configuration combinations, each output
+knows the set of CRTCs that it can be connected to as well as the set of
+other outputs which can be simutaneously connected to a CRTC.
+
+2.1.2 CRTC overview
+
+CRTCs serve only to stream frame buffer data to outputs using a mode line.
+Ideally, they would not be presented to the user at all, and in fact the
+configuration file doesn't expose them. The RandR 1.2 protocol does, but the
+hope there is that client-side applications will hide them carefully away.
+
+Each crtc has an associated cursor, along with the current configuration.
+All of the data needed to determine valid configurations is contained within
+the Outputs.
+
+2.2 Configuration overview
+
+As outputs drive monitors, the "Monitor" section has been repurposed to
+define their configuration. This provides for a bit more syntax than
+the large list of driver-specific options that were used in the past for
+similar configuration.
+
+However, the existing "Monitor" section referenced by the active "Screen"
+section no longer has any use at all; some sensible meaning for this
+parameter is needed now that a Screen can have multiple Monitors.
+
+3. Public Functions
+
+3.1 PreInit functions
+
+These functions should be used during the driver PreInit phase, they are
+arranged in the order they should be invoked.
+
+    void
+    xf86CrtcConfigInit (ScrnInfoPtr			scrn
+			const xf86CrtcConfigFuncsRec	*funcs)
+
+This function allocates and initializes structures needed to track CRTC and
+Output state.
+
+    void
+    xf86CrtcSetSizeRange (ScrnInfoPtr scrn,
+			  int minWidth, int minHeight,
+			  int maxWidth, int maxHeight)
+
+This sets the range of screen sizes supported by the driver.
+
+    xf86CrtcPtr
+    xf86CrtcCreate (ScrnInfoPtr             scrn,
+		    const xf86CrtcFuncsRec  *funcs)
+    
+Create one CRTC object. See the discussion below for a description of the
+contents of the xf86CrtcFuncsRec. Note that this is done in PreInit, so it
+should not be re-invoked at each server generation. Create one of these for
+each CRTC present in the hardware.
+    
+    xf86OutputPtr
+    xf86OutputCreate (ScrnInfoPtr              scrn,
+		      const xf86OutputFuncsRec *funcs,
+		      const char	       *name)
+
+Create one Output object. See the discussion below for a description of the
+contents of the xf86OutputFuncsRec. This is also called from PreInit and
+need not be re-invoked at each ScreenInit time. An Output should be created
+for every Output present in the hardware, not just for outputs which have
+detected monitors.
+    
+    Bool
+    xf86OutputRename (xf86OutputPtr output, const char *name)
+
+If necessary, the name of an output can be changed after it is created using
+this function.
+    
+    Bool
+    xf86InitialConfiguration (ScrnInfoPtr scrn, Bool canGrow)
+
+Using the resources provided, and the configuration specified by the user,
+this function computes an initial configuration for the server. It tries to
+enable as much hardware as possible using some fairly simple heuristics. 
+
+The 'canGrow' parameter indicates that the frame buffer does not have a fixed
+size (fixed size frame buffers are required by XAA). When the frame buffer
+has a fixed size, the configuration selects a 'reasonablely large' frame
+buffer so that common reconfiguration options are possible. For resizable
+frame buffers, the frame buffer is set to the smallest size that encloses
+the desired configuration.
+    
+3.2 ScreenInit functions
+
+These functions should be used during the driver ScreenInit phase.
+
+    Bool
+    xf86DiDGAInit (ScreenPtr screen, unsigned long dga_address)
+
+This function provides driver-independent accelerated DGA support for some
+of the DGA operations; using this, the driver can avoid needing to implement
+any of the rest of DGA.
+
+    Bool
+    xf86SaveScreen(ScreenPtr pScreen, int mode)
+
+Stick this in pScreen->SaveScreen and the core X screen saver will be
+implemented by disabling outputs and crtcs using their dpms functions.
+
+    void
+    xf86DPMSSet(ScrnInfoPtr scrn, int mode, int flags)
+
+Pass this function to xf86DPMSInit and all DPMS mode switching will be
+managed by using the dpms functions provided by the Outputs and CRTCs.
+
+    Bool
+    xf86CrtcScreenInit (ScreenPtr screen)
+
+This function completes the screen initialization process for the crtc and
+output objects. Call it near the end of the ScreenInit function, after the
+frame buffer and acceleration layers have been added.
+
+3.3 EnterVT functions
+
+Functions used during EnterVT, or whenever the current configuration needs
+to be applied to the hardware.
+
+    Bool
+    xf86SetDesiredModes (ScrnInfoPtr scrn)
+
+xf86InitialConfiguration selects the desired configuration at PreInit time;
+when the server finally hits ScreenInit, xf86SetDesiredModes is used by the
+driver to take that configuration and apply it to the hardware. In addition,
+successful mode selection at other times updates the configuration that will
+be used by this function, so LeaveVT/EnterVT pairs can simply invoke this
+and return to the previous configuration.
+
+3.4 SwitchMode functions
+
+Functions called from the pScrn->SwitchMode hook, which is used by the
+XFree86-VidModeExtension and the keypad mode switch commands.
+
+    Bool
+    xf86SetSingleMode (ScrnInfoPtr	scrn, 
+		       DisplayModePtr   desired,
+		       Rotation		rotation)
+
+This function applies the specified mode to all active outputs. Which is to
+say, it picks reasonable modes for all active outputs, attempting to get the
+screen to the specified size while not breaking anything that is currently
+working.
+
+3.7 get_modes functions
+
+Functions called during output->get_modes to help build lists of modes
+
+    xf86MonPtr
+    xf86OutputGetEDID (xf86OutputPtr output, I2CBusPtr pDDCBus)
+
+This returns the EDID data structure for the 'output' using the I2C bus
+'pDDCBus'. This has no effect on 'output' itself.
+
+    void
+    xf86OutputSetEDID (xf86OutputPtr output, xf86MonPtr edid_mon)
+
+Once the EDID data has been fetched, this call applies the EDID data to the
+output object, setting the physical size and also various properties, like
+the DDC root window property (when output is the 'compat' output), and the
+RandR 1.2 EDID output properties.
+
+    DisplayModePtr
+    xf86OutputGetEDIDModes (xf86OutputPtr output)
+
+Given an EDID data structure, this function computes a list of suitable
+modes. This function also applies a sequence of 'quirks' during this process
+so that the returned modes may not actually match the mode data present in
+the EDID data.
+
+3.6 Other functions
+
+These remaining functions in the API can be used by the driver as needed.
+
+    Bool
+    xf86CrtcSetMode (xf86CrtcPtr crtc, DisplayModePtr mode, Rotation rotation,
+		     int x, int y)
+
+Applies a mode to a CRTC. All of the outputs which are currently using the
+specified CRTC are included in the mode setting process. 'x' and 'y' are the
+offset within the frame buffer that the crtc is placed at. No checking is
+done in this function to ensure that the mode is usable by the active
+outputs.
+    
+    void
+    xf86ProbeOutputModes (ScrnInfoPtr pScrn, int maxX, int maxY)
+
+This discards the mode lists for all outputs, re-detects monitor presence
+and then acquires new mode lists for all monitors which are not disconnected.
+Monitor configuration data is used to modify the mode lists returned by the
+outputs. 'maxX' and 'maxY' limit the maximum size modes that will be
+returned.
+    
+    void
+    xf86SetScrnInfoModes (ScrnInfoPtr pScrn)
+
+This copies the 'compat' output mode list into the pScrn modes list which is
+used by the XFree86-VidModeExtension and the keypad mode switching
+operations. The current 'desired' mode for the CRTC associated with the
+'compat' output is placed first in this list to indicate the current mode.
+Usually, the driver won't need to call this function as
+xf86InitialConfiguration will do so automatically, as well as any RandR
+functions which reprobe for modes. However, if the driver reprobes for modes
+at other times using xf86ProbeOutputModes, this function needs to be called.
+    
+    Bool
+    xf86DiDGAReInit (ScreenPtr pScreen)
+
+This is similar to xf86SetScrnInfoModes, but it applies the 'compat' output
+mode list to the set of modes advertised by the DGA extension; it needs to
+be called whenever xf86ProbeOutputModes is invoked.
+
+    void
+    xf86DisableUnusedFunctions(ScrnInfoPtr pScrn)
+
+After any sequence of calls using xf86CrtcSetMode, this function cleans up
+any leftover Output and CRTC objects by disabling them, saving power. It is
+safe to call this whenever the server is running as it only disables objects
+which are not currently in use.
+    
+4. CRTC operations
+
+4.1 CRTC functions
+
+These functions provide an abstract interface for the CRTC object; most
+manipulation of the CRTC object is done through these functions.
+
+    void
+    crtc->funcs->dpms (xf86CrtcPtr crtc, int mode)
+
+Where 'mode' is one of DPMSModeOff, DPMSModeSuspend, DPMSModeStandby or
+DPMSModeOn. This requests that the crtc go to the specified power state.
+When changing power states, the output dpms functions are invoked before the
+crtc dpms functions.
+
+    void
+    crtc->funcs->save (xf86CrtcPtr crtc)
+	
+    void
+    crtc->funcs->restore (xf86CrtcPtr crtc)
+
+Preserve/restore any register contents related to the CRTC. These are
+strictly a convenience for the driver writer; if the existing driver has
+fully operation save/restore functions, you need not place any additional
+code here. In particular, the server itself never uses this function.
+
+    Bool
+    crtc->funcs->lock (xf86CrtcPtr crtc)
+	
+    void
+    crtc->funcs->unlock (xf86CrtcPtr crtc)
+
+These functions are invoked around mode setting operations; the intent is
+that DRI locking be done here to prevent DRI applications from manipulating
+the hardware while the server is busy changing the output configuration. If
+the lock function returns FALSE, the unlock function will not be invoked.
+
+    Bool
+    crtc->funcs->mode_fixup (xf86CrtcPtr crtc, 
+			     DisplayModePtr mode,
+			     DisplayModePtr adjusted_mode)
+
+This call gives the CRTC a chance to see what mode will be set and to
+comment on the mode by changing 'adjusted_mode' as needed. This function
+shall not modify the state of the crtc hardware at all. If the CRTC cannot
+accept this mode, this function may return FALSE.
+
+    void
+    crtc->funcs->prepare (xf86CrtcPtr crtc)
+
+This call is made just before the mode is set to make the hardware ready for
+the operation. A usual function to perform here is to disable the crtc so
+that mode setting can occur with clocks turned off and outputs deactivated.
+
+    void
+    crtc->funcs->mode_set (xf86CrtcPtr crtc,
+			   DisplayModePtr mode,
+			   DisplayModePtr adjusted_mode)
+
+This function applies the specified mode (possibly adjusted by the CRTC
+and/or Outputs).
+
+    void
+    crtc->funcs->commit (xf86CrtcPtr crtc)
+
+Once the mode has been applied to the CRTC and Outputs, this function is
+invoked to let the hardware turn things back on.
+
+    void
+    crtc->funcs->gamma_set (xf86CrtcPtr crtc, CARD16 *red,
+			    CARD16 *green, CARD16 *blue, int size)
+
+This function adjusts the gamma ramps for the specified crtc.
+
+    void *
+    crtc->funcs->shadow_allocate (xf86CrtcPtr crtc, int width, int height)
+
+This function allocates frame buffer space for a shadow frame buffer. When
+allocated, the crtc must scan from the shadow instead of the main frame
+buffer. This is used for rotation. The address returned is passed to the
+shadow_create function. This function should return NULL on failure.
+
+    PixmapPtr
+    crtc->funcs->shadow_create (xf86CrtcPtr crtc, void *data,
+				int width, int height)
+
+This function creates a pixmap object that will be used as a shadow of the
+main frame buffer for CRTCs which are rotated or reflected. 'data' is the
+value returned by shadow_allocate.
+
+    void
+    crtc->funcs->shadow_destroy (xf86CrtcPtr crtc, PixmapPtr pPixmap,
+				 void *data)
+
+Destroys any associated shadow objects. If pPixmap is NULL, then a pixmap
+was not created, but 'data' may still be non-NULL indicating that the shadow
+had been allocated.
+
+    void
+    crtc->funcs->destroy (xf86CrtcPtr crtc)
+
+When a CRTC is destroyed (which only happens in error cases), this function
+can clean up any driver-specific data.
+
+4.2 CRTC fields
+
+The CRTC object is not opaque; there are several fields of interest to the
+driver writer.
+
+    struct _xf86Crtc {
+	/**
+	 * Associated ScrnInfo
+	 */
+	ScrnInfoPtr     scrn;
+    
+	/**
+	 * Active state of this CRTC
+	 *
+	 * Set when this CRTC is driving one or more outputs
+	 */
+	Bool            enabled;
+    
+	/** Track whether cursor is within CRTC range  */
+	Bool            cursorInRange;
+    
+	/** Track state of cursor associated with this CRTC */
+	Bool            cursorShown;
+    
+	/**
+	 * Active mode
+	 *
+	 * This reflects the mode as set in the CRTC currently
+	 * It will be cleared when the VT is not active or
+	 * during server startup
+	 */
+	DisplayModeRec  mode;
+	Rotation        rotation;
+	PixmapPtr       rotatedPixmap;
+	void            *rotatedData;
+    
+	/**
+	 * Position on screen
+	 *
+	 * Locates this CRTC within the frame buffer
+	 */
+	int             x, y;
+    
+	/**
+	 * Desired mode
+	 *
+	 * This is set to the requested mode, independent of
+	 * whether the VT is active. In particular, it receives
+	 * the startup configured mode and saves the active mode
+	 * on VT switch.
+	 */
+	DisplayModeRec  desiredMode;
+	Rotation        desiredRotation;
+	int             desiredX, desiredY;
+    
+	/** crtc-specific functions */
+	const xf86CrtcFuncsRec *funcs;
+    
+	/**
+	 * Driver private
+	 *
+	 * Holds driver-private information
+	 */
+	void            *driver_private;
+    #ifdef RANDR_12_INTERFACE
+	/**
+	 * RandR crtc
+	 *
+	 * When RandR 1.2 is available, this
+	 * points at the associated crtc object
+	 */
+	RRCrtcPtr       randr_crtc;
+    #else
+	void            *randr_crtc;
+    #endif
+    };
+
+    
+5. Output functions.
+
+6. Configuration
+
+Because the configuration file syntax is fixed,
+this was done by creating new "Driver" section options that hook specific
+outputs to specific "Monitor" sections in the file. The option:
+section of the form:
+
+	Option	"monitor-VGA" "My VGA Monitor"
+
+connects the VGA output of this driver to the "Monitor" section with
+Identifier "My VGA Monitor". All of the usual monitor options can now be
+placed in that "Monitor" section and will be applied to the VGA output
+configuration.

+information is intended for experienced Linux developers.  Beginners are
+probably better off installing precompiled packages.

+
+3.  Prerequisites
+
+You'll need the following:
+
+   o An installation of XFree86 4.1 or later.  The DRI tree has been pruned
+     down to minimize its size.  But in order to build the DRI tree you need
+     to have recent X header files, etc. already installed.  If you don't
+     have XFree86 4.1 (or later) installed you can probably install it from
+     RPMs (or another package format).  Or, you can download XFree86 as
+     sources and compile/install it yourself.
+
+   o At least 200MB of free disk space.  If you compile for debugging (the -g
+     option) then you'll need about 600MB.
+
+   o GCC compiler and related tools.
+
+   o ssh (secure shell) if you're a DRI developer and don't want to use
+     anonymous CVS download.
+
+   o A 2.4.x Linux Kernel.  See below for details.
+
+   o FreeBSD support is not currently being maintained and may not work.
+
+The DRI 3D drivers generally work on systems with Intel or AMD CPUs.  How-
+ever, limited support for Alpha and PowerPC support is underway.
+
+For 3dfx Voodoo hardware, you'll also need the Glide3 runtime library
+(libglide3-v3.so for Voodoo3 or libglide3-v5.so for Voodoo4/5).  These can be
+downloaded from the DRI website.  You can compile them yourself, but it's
+often a painful process.
+
+For Matrox G200/G400, Intel i810/i830 or ATI Rage128/Radeon hardware, you'll
+also need AGP support in your Linux kernel, either built-in or as a loadable
+module.
+
+4.  Linux Kernel Preparation
+
+Only the Linux 2.4.x kernels are currently supported by the DRI hardware
+drivers.  2.5.x kernels may work, but aren't tested.
+
+Most of the DRI drivers require AGP support and using Intel Pentium III SSE
+optimizations also requires an up-to-date Linux kernel.  Configuring your
+kernel correctly is very important, as features such as SSE optimizations
+will be disabled if your kernel does not support them.  Thus, if you have a
+Pentium III processor, you must configure your kernel for the Pentium III
+processor family.
+
+Building a new Linux kernel can be difficult for beginners but there are
+resources on the Internet to help.  This document assumes experience with
+configuring, building and installing Linux kernels.
+
+Linux kernels can be downloaded from www.kernel.org
+
+Here are the basic steps for kernel setup.
+
+   o Download the needed kernel and put it in /usr/src.  Create a directory
+     for the source and unpack it.  For example:
+
+                    cd /usr/src
+                    rm -f linux
+                    mkdir linux-2.4.x
+                    ln -s linux-2.4.x linux
+                    bzcat linux-2.4.x.tar.bz2 | tar xf -
+
+     It is critical that /usr/src/linux point to your new kernel sources,
+     otherwise the kernel headers will not be used when building the DRI.
+     This will almost certainly cause compilation problems.
+
+   o Read /usr/src/linux/Documentation/Changes.  This file lists the minimum
+     requirements for all software packages required to build the kernel.
+     You must upgrade at least gcc, make, binutils and modutils to at least
+     the versions specified in this file.  The other packages may not be
+     needed.  If you are upgrading from Linux 2.2.x you must upgrade your
+     modutils package for Linux 2.4.x.
+
+   o Configure your kernel.  You might, for example, use make menuconfig and
+     do the following:
+
+        o Go to Code maturity level options
+
+        o Enable Prompt for development and/or incomplete code/drivers
+
+        o hit ESC to return to the top-level menu
+
+        o Go to Processor type and features
+
+        o Select your processor type from Processor Family
+
+        o hit ESC to return to the top-level menu
+
+        o Go to Character devices
+
+        o Disable Direct Rendering Manager (XFree86 DRI support) since we'll
+          use the DRI code from the XFree86/DRI tree and will compile it
+          there.
+
+        o Go to /dev/agpgart (AGP Support) (EXPERIMENTAL) (NEW)
+
+        o Hit SPACE twice to build AGP support into the kernel
+
+        o Enable all chipsets' support for AGP
+
+        o It's recommended that you turn on MTRRs under Processor type and
+          Features, but not required.
+
+   o Configure the rest of the kernel as required for your system (i.e. Eth-
+     ernet, SCSI, etc)
+
+   o Exit, saving your kernel configuration.
+
+   o Edit your /etc/lilo.conf file.  Make sure you have an image entry as
+     follows (or similar):
+
+                      image=/boot/vmlinuz
+                            label=linux.2.4.x
+                            read-only
+                            root=/dev/hda1
+
+     The important part is that you have /boot/vmlinuz without a trailing
+     version number.  If this is the first entry in your /etc/lilo.conf AND
+     you haven't set a default, then this will be your default kernel.
+
+   o Compile the new kernel.
+
+                    cd /usr/src/linux-2.4.x
+                    make dep
+                    make bzImage
+                    make modules
+                    make modules_install
+                    make install
+
+     Note that last make command will automatically run lilo for you.
+
+   o Now reboot to use the new kernel.
+
+5.  CPU Architectures
+
+In general, nothing special has to be done to use the DRI on different CPU
+architectures.  There are, however, a few optimizations that are CPU-depen-
+dent.  Mesa will determine at runtime which CPU-dependent optimizations
+should be used and enable them where appropriate.
+
+5.1  Intel Pentium III Features
+
+The Pentium III SSE instructions are used in optimized vertex transformation
+functions in the Mesa-based DRI drivers.  On Linux, SSE requires a recent
+kernel (such as 2.4.0-test11 or later) both at compile time and runtime.
+
+5.2  AMD 3DNow! Features
+
+AMD's 3DNow! instructions are used in optimized vertex transformation func-
+tions in the Mesa-based DRI drivers.  3DNow! is supported in most versions of
+Linux.
+
+5.3  Alpha Features
+
+On newer Alpha processors a significant performance increase can be seen with
+the addition of the -mcpu= option to GCC.  This option is dependent on the
+architecture of the processor.  For example, -mcpu=ev6 will build specifi-
+cally for the EV6 based AXP's, giving both byte and word alignment access to
+the DRI/Mesa drivers.
+
+To enable this optimization edit your xc/config/host.def file and add the
+line:
+
+#define DefaultGcc2AxpOpt -O2 -mcpu=ev6
+
+Additional speed improvements to 3D rendering can be achieved by installing
+Compaq's Math Libraries (CPML) which can be obtained from http://www.sup-
+port.compaq.com/alpha-tools/software/index.html
+
+Once installed, you can add this line to your host.def to build with the CPML
+libraries:
+
+#define UseCompaqMathLibrary YES
+
+The host.def file is explained below.
+
+6.  Downloading the XFree86/DRI CVS Sources
+
+The DRI project is hosted by SourceForge.  The DRI source code, which is a
+subset of the XFree86 source tree, is kept in a CVS repository there.
+
+The DRI CVS sources may be accessed either anonymously or as a registered
+SourceForge user.  It's recommended that you become a registered SourceForge
+user so that you may submit non-anonymous bug reports and can participate in
+the mailing lists.
+
+6.1  Anonymous CVS download:
+
+  1.  Create a directory to store the CVS files:
+
+                       cd ~
+                       mkdir DRI-CVS
+
+      You could put your CVS directory in a different place but we'll use
+      ~/DRI-CVS/ here.
+
+  2.  Check out the CVS sources:
+
+                       cd ~/DRI-CVS
+                       cvs -d:pserver:anonymous@cvs.dri.sourceforge.net:/cvsroot/dri login
+                         (hit ENTER when prompted for a password)
+                       cvs -z3 -d:pserver:anonymous@cvs.dri.sourceforge.net:/cvsroot/dri co xc
+
+      The -z3 flag causes compression to be used in order to reduce the down-
+      load time.
+
+6.2  Registered CVS download:
+
+  1.  Create a directory to store the CVS files:
+
+                       cd ~
+                       mkdir DRI-CVS
+
+      You could put your CVS directory in a different place but we'll use
+      ~/DRI-CVS/ here.
+
+  2.  Set the CVS_RSH environment variable:
+
+                       setenv CVS_RSH ssh      // if using csh or tcsh
+                       export CVS_RSH=ssh      // if using sh or bash
+
+  3.  Check out the CVS sources:
+
+                       cd ~/DRI-CVS
+                       cvs -z3 -d:ext:YOURID@cvs.dri.sourceforge.net:/cvsroot/dri co xc
+
+      Replace YOURID with your CVS login name.  You'll be prompted to enter
+      your sourceforge password.
+
+      The -z3 flag causes compression to be used in order to reduce the down-
+      load time.
+
+6.3  Updating your CVS sources
+
+In the future you'll want to occasionally update your local copy of the DRI
+source code to get the latest changes.  This can be done with:
+
+                cd ~/DRI-CVS
+                cvs -z3 update -dA xc
+
+The -d flag causes any new subdirectories to be created and -A causes most
+recent trunk sources to be fetched, not branch sources.
+
+7.  Mesa
+
+Most of the DRI 3D drivers are based on Mesa (the free implementation of the
+OpenGL API).  The relevant files from Mesa are already included in the
+XFree86/DRI source tree.  There is no need to download or install the Mesa
+source files separately.
+
+Sometimes a newer version of Mesa will be available than the version included
+in XFree86/DRI.  Upgrading Mesa within XFree86/DRI is not always straightfor-
+ward.  It can be an error-prone undertaking, especially for beginners, and is
+not generally recommended.  The DRI developers will upgrade Mesa when appro-
+priate.
+
+8.  Compiling the XFree86/DRI tree
+
+8.1  Make a build tree
+
+Rather than placing object files and library files right in the source tree,
+they're instead put into a parallel build tree.  The build tree is made with
+the lndir command:
+
+                 cd ~/DRI-CVS
+                 ln -s xc XFree40
+                 mkdir build
+                 cd build
+                 lndir -silent -ignorelinks ../XFree40
+
+The build tree will be populated with symbolic links which point back into
+the CVS source tree.
+
+Advanced users may have several build trees for compiling and testing with
+different options.
+
+8.2  Edit the host.def file
+
+The ~/DRI-CVS/build/xc/config/cf/host.def file is used to configure the
+XFree86 build process.  You can change it to customize your build options or
+make adjustments for your particular system configuration
+
+The default host.def file will look something like this:
+
+                 #define DefaultCCOptions -Wall
+     (i386)      #define DefaultGcc2i386Opt -O2
+     (Alpha)     #define DefaultGcc2AxpOpt -O2 -mcpu=ev6 (or similar)
+                 #define LibraryCDebugFlags -O2
+                 #define BuildServersOnly YES
+                 #define XF86CardDrivers vga tdfx mga ati i810
+                 #define LinuxDistribution LinuxRedHat
+                 #define DefaultCCOptions -ansi GccWarningOptions -pipe
+                 #define BuildXF86DRI YES
+                 /* Optionally turn these on for debugging */
+                 /* #define GlxBuiltInTdfx YES */
+                 /* #define GlxBuiltInMga YES */
+                 /* #define GlxBuiltInR128 YES */
+                 /* #define GlxBuiltInRadeon YES */
+                 /* #define DoLoadableServer NO */
+                 #define SharedLibFont NO
+
+The ProjectRoot variable specifies where the XFree86 files will be installed.
+We recommend installing the DRI files over your existing XFree86 installation
+- it's generally safe to do and less error-prone.  This policy is different
+than what we used to recommend.
+
+If XFree86 4.x is not installed in /usr/X11R6/ you'll have to add the follow-
+ing to the host.def file:
+
+                 #define ProjectRoot pathToYourXFree86installation
+
+Note the XF86CardDrivers line to be sure your card's driver is listed.
+
+If you want to enable 3DNow! optimizations in Mesa and the DRI drivers, you
+should add the following:
+
+                 #define MesaUse3DNow YES
+
+You don't have to be using an AMD processor in order to enable this option.
+The DRI will look for 3DNow! support and runtime and only enable it if appli-
+cable.
+
+If you want to enable SSE optimizations in Mesa and the DRI drivers, you must
+upgrade to a Linux 2.4.x kernel.  Mesa will verify that SSE is supported by
+both your processor and your operating system, but to build Mesa inside the
+DRI you need to have the Linux 2.4.x kernel headers in /usr/src/linux.  If
+you enable SSE optimizations with an earlier version of the Linux kernel in
+/usr/src/linux, Mesa will not compile.  You have been warned.  If you do have
+a 2.4.x kernel, you should add the following:
+
+                 #define MesaUseSSE YES
+
+If you want to build the DRM kernel modules as part of the full build pro-
+cess, add the following:
+
+                 #define BuildXF86DRM YES
+
+Otherwise, you'll need to build them separately as described below.
+
+8.3  Compilation
+
+To compile the complete DRI tree:
+
+                 cd ~/DRI-CVS/build/xc/
+                 make World >& world.log
+
+Or if you want to watch the compilation progress:
+
+                 cd ~/DRI-CVS/build/xc/
+                 make World >& world.log &
+                 tail -f world.log
+
+With the default compilation flags it's normal to get a lot of warnings dur-
+ing compilation.
+
+Building will take some time so you may want to go check your email or visit
+slashdot.
+
+WARNING: do not use the -j option with make.  It's reported that it does not
+work with XFree86/DRI.
+
+8.4  Check for compilation errors
+
+Using your text editor, examine world.log for errors by searching for the
+pattern ***.
+
+After fixing the errors, run make World again.  Later, you might just compile
+parts of the source tree but it's important that the whole tree will build
+first.
+
+If you edited your host.def file to enable automatic building of the DRI ker-
+nel module(s), verify that they were built:
+
+               cd ~/DRI-CVS/build/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel
+               ls
+
+Otherwise, build them now by running
+
+               cd ~/DRI-CVS/build/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel
+               make -f Makefile.linux
+
+For the 3dfx Voodoo, you should see tdfx.o.  For the Matrox G200/G400, you
+should see mga.o.  For the ATI Rage 128, you should see r128.o.  For the ATI
+Radeon, you should see radeon.o.  For the Intel i810, you should see i810.o.
+
+If the DRI kernel module(s) failed to build you should verify that you're
+using the right version of the Linux kernel.  The most recent kernels are not
+always supported.
+
+If your build machine is running a different version of the kernel than your
+target machine (i.e. 2.2.x vs. 2.4.x), make will select the wrong kernel
+source tree. This can be fixed by explicitly setting the value of LINUXDIR.
+If the path to your kernel source is /usr/src/linux-2.4.x,
+
+               cd ~/DRI-CVS/build/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel
+               make -f Makefile.linux LINUXDIR=/usr/src/linux-2.4.x
+
+or alternatively, edit Makefile.linux to set LINUXDIR before the ifndef LIN-
+UXDIR line.
+
+8.5  DRI kernel module installation
+
+The DRI kernel modules will be in ~/DRI-CVS/build/xc/pro-
+grams/Xserver/hw/xfree86/os-support/linux/drm/kernel/.
+
+To load the appropriate DRM module in your running kernel you can either use
+ismod and restart your X server or copy the kernel module to /lib/mod-
+ules/2.4.x/kernel/drivers/char/drm/ then run depmod and restart your X
+server.
+
+Make sure you first unload any older DRI kernel modules that might be already
+loaded.
+
+Note that some DRM modules require that the agpgart module be loaded first.
+
+9.  Normal Installation and Configuration
+
+Most users will want to install the new X server and use it in place of their
+old X server.  This section explains how to do that.
+
+Developers, on the other hand, may just want to test the X server without
+actually installing it as their default server.  If you want to do that, skip
+to the next section.
+
+9.1  Installation
+
+Here are the installation commands:
+
+                su
+                cd ~/DRI-CVS/build/xc
+                make install
+
+9.2  Update the XF86Config File
+
+You may need to edit your XF86Config file to enable the DRI.  The config file
+is usually installed as /etc/X11/XF86Config-4.  See the DRI User Guide for
+details, but basically, you need to load the "glx" and "dri" modules and add
+a "DRI" section.
+
+On the DRI web site, in the resources section, you'll find example XF86Config
+files for a number of graphics cards.  These configuration files also setup
+DRI options so it's highly recommended that you look at these examples.
+
+The XFree86 4.x server can generate a basic configuration file itself.  Sim-
+ply do this:
+
+                  cd /usr/X11R6/bin
+                  ./XFree86 -configure
+
+A file named /root/XF86Config.new will be created.  It should allow you to
+try your X server but you'll almost certainly have to edit it.  For example,
+you should add HorizSync and VertRefresh options to the Monitor section and
+Modes options to the Screen section.  Also, the ModulePath option in the
+Files section should be set to /usr/X11R6/lib/modules.
+
+9.3  Start the New X Server
+
+The new X server should be ready to use now.  Start your X server in your
+usual manner.  Often times the startx command is used:
+
+                  startx
+
+10.  Testing the Server Without Installing It
+
+As mentioned at the start of section 9, developers may want to simply run the
+X server without installing it.  This can save some time and allow you to
+keep a number of X servers available for testing.
+
+10.1  Configuration
+
+As described in the preceding section, you'll need to create a configuration
+file for the new server.  Put the XF86Config file in your ~/DRI-
+CVS/build/xc/programs/Xserver directory.
+
+Be sure the ModulePath option in your XF86Config file is set correctly.
+
+10.2  A Startup Script
+
+A simple shell script can be used to start the X server.  Here's an example.
+
+             #!/bin/sh
+             export DISPLAY=:0
+             ./XFree86 -xf86config XF86Config & \
+             sleep 2
+             fvwm2 &
+             xset b off
+             xmodmap -e "clear mod4"
+             xsetroot -solid "#00306f"
+             xterm -geometry 80x40+0+0
+
+You might name this script start-dri.  Put it in your ~/DRI-CVS/build/xc/pro-
+grams/Xserver directory.
+
+To test the server run the script:
+
+                  cd ~/DRI-CVS/build/xc/programs/Xserver
+                  ./start-dri
+
+For debugging, you may also want to capture the log messages printed by the
+server in a file.  If you're using the C-shell:
+
+                  ./start-dri >& log
+
+11.  Where To Go From Here
+
+At this point your X server should be up and running with hardware-acceler-
+ated direct rendering.  Please read the DRI User Guide for information about
+trouble shooting and how to use the DRI-enabled X server for 3D applications.

+Adding EXA support to your X.Org video driver
+---------------------------------------------
+EXA (for EXcellent Architecture or Ex-kaa aXeleration Architecture or
+whatever) aims to extend the life of the venerable XFree86 video drivers by
+introducing a new set of acceleration hooks that efficiently accelerate the X
+Render extension, including solid fills, blits within screen memory and to and
+from system memory, and Porter-Duff compositing and transform operations.
+
+Configuration
+-------------
+A new config file option, AccelMethod, should be added to your driver, to allow
+the user to select between the EXA and XAA acceleration APIs.
+
+Some drivers implement a per-instance useEXA flag to track whether EXA is
+active or not.  It can be helpful to also conditionalize XAA support with an
+ifdef so that it can easily be turned off/removed in the future.
+
+Setting the flag and checking for AccelMethod can be done in the driver's
+Options parsing routine.
+
+Loading EXA
+------------
+EXA drivers in the XFree86 DDX should use the loadable module loader to load
+the EXA core.  Careful versioning allows the EXA API to be extended without
+breaking the ABI for older versions of drivers.  Example code for loading EXA:
+
+static const char *exaSymbols[] = {
+    "exaDriverAlloc",
+    "exaDriverInit",
+    "exaDriverFini",
+    "exaOffscreenAlloc",
+    "exaOffscreenFree",
+    "exaGetPixmapOffset",
+    "exaGetPixmapPitch",
+    "exaGetPixmapSize",
+    "exaMarkSync",
+    "exaWaitSync",
+    NULL
+};
+
+	if (info->useEXA) {
+	    info->exaReq.majorversion = 2;
+	    info->exaReq.minorversion = 0;
+
+	    if (!LoadSubModule(pScrn->module, "exa", NULL, NULL, NULL,
+			       &info->exaReq, &errmaj, &errmin)) {
+		LoaderErrorMsg(NULL, "exa", errmaj, errmin);
+		return FALSE;
+	    }
+	    xf86LoaderReqSymLists(exaSymbols, NULL);
+	}
+
+EXA is then initialized using exaDriverAlloc and exaDriverInit.  See doxygen
+documentation for getting started there.
+
+Further documentation
+------------
+The EXA driver interface and public API is documented using doxygen in
+xserver/xorg/exa/.  To build the documentation, run:
+  doxygen -g
+  doxygen Doxyfile
+The resulting documentation will appear an html/index.html under the current
+directory.
+
+EXA initialization
+------------------
+Your driver's AccelInit routine must initialize an ExaDriverRec structure if
+EXA support is enabled, with appropriate error handling (i.e.  NoAccel and
+NoXvideo should be set to true if EXA fails to initialize for whatever
+reason).
+
+The AccelInit routine also needs to make sure that there's enough offscreen
+memory for certain operations to function, like Xvideo, which should advertise
+a maximum size no larger than can be dealt with given the amount of offscreen
+memory available.
+
+EXA and Xv
+----------
+Video support becomes easier with EXA since AllocateFBMemory can use
+exaOffscreenAlloc directly, freeing a previous area if necessary and
+allocating a new one.  Likewise, FreeFBMemory can call exaOffscreenFree.
+
+EXA teardown
+------------
+At screen close time, EXA drivers should call exaDriverFini with their screen
+pointer, free their EXADriver structure, and do any other necessary teardown.
+
+EXA misc.
+---------
+In many drivers, DGA support will need to be changed to be aware of the new
+EXA support.

+.SH NAME
+__xservername__ - X11R7 X server
+.SH SYNOPSIS
+.B __xservername__
+.RI [\fB:\fP display ]
+.RI [ option
+.IR ... ]
+.SH DESCRIPTION
+.B __xservername__
+is a full featured X server that was originally designed for UNIX and
+UNIX-like operating systems running on Intel x86 hardware.  It now runs
+on a wider range of hardware and OS platforms.
+.PP
+This work was derived by the X.Org Foundation from the XFree86 Project's
+.I "XFree86\ 4.4rc2"
+release.
+The XFree86 release was originally derived from
+.I "X386\ 1.2"
+by Thomas Roell which was contributed to X11R5 by Snitily Graphics
+Consulting Service.
+.SH PLATFORMS
+.PP
+.B __xservername__
+operates under a wide range of operating systems and hardware platforms.
+The Intel x86 (IA32) architecture is the most widely supported hardware
+platform.  Other hardware platforms include Compaq Alpha, Intel IA64, AMD64,
+SPARC and PowerPC.  The most widely supported operating systems are the
+free/OpenSource UNIX-like systems such as Linux, FreeBSD, NetBSD,
+OpenBSD, and Solaris.  Commercial UNIX operating systems such as
+UnixWare are also supported.  Other supported operating systems include
+GNU Hurd.  Mac OS X is supported with the
+Xquartz(__appmansuffix__) X server.  Win32/Cygwin is supported with the
+XWin(__appmansuffix__) X server.
+.PP
+.SH "NETWORK CONNECTIONS"
+.B __xservername__
+supports connections made using the following reliable
+byte-streams:
+.TP 4
+.I "Local"
+On most platforms, the "Local" connection type is a UNIX-domain socket.
+On some System V platforms, the "local" connection types also include
+STREAMS pipes, named pipes, and some other mechanisms.
+.TP 4
+.I TCP\/IP
+.B __xservername__
+listens on port
+.RI 6000+ n ,
+where
+.I n
+is the display number.  This connection type can be disabled with the
+.B \-nolisten
+option (see the Xserver(1) man page for details).
+.SH "ENVIRONMENT VARIABLES"
+For operating systems that support local connections other than Unix
+Domain sockets (SVR3 and SVR4), there is a compiled-in list specifying
+the order in which local connections should be attempted.  This list
+can be overridden by the
+.I XLOCAL
+environment variable described below.  If the display name indicates a
+best-choice connection should be made (e.g.
+.BR :0.0 ),
+each connection mechanism is tried until a connection succeeds or no
+more mechanisms are available.  Note: for these OSs, the Unix Domain
+socket connection is treated differently from the other local connection
+types.  To use it the connection must be made to
+.BR unix:0.0 .
+.PP
+The
+.I XLOCAL
+environment variable should contain a list of one more
+more of the following:
+.PP
+.RS 8
+.nf
+NAMED
+PTS
+SCO
+ISC
+.fi
+.RE
+.PP
+which represent SVR4 Named Streams pipe, Old-style USL Streams pipe,
+SCO XSight Streams pipe, and ISC Streams pipe, respectively.  You can
+select a single mechanism (e.g.
+.IR XLOCAL=NAMED ),
+or an ordered list (e.g. \fIXLOCAL="NAMED:PTS:SCO"\fP).
+his variable overrides the compiled-in defaults.  For SVR4 it is
+recommended that
+.I NAMED
+be the first preference connection.  The default setting is
+.IR PTS:NAMED:ISC:SCO .
+.PP
+To globally override the compiled-in defaults, you should define (and
+export if using
+.B sh
+or
+.BR ksh )
+.I XLOCAL
+globally.  If you use startx(1) or xinit(1), the definition should be
+at the top of your
+.I .xinitrc
+file.  If you use xdm(1), the definitions should be early on in the
+.I __projectroot__/lib/X11/xdm/Xsession
+script.
+.SH OPTIONS
+.B __xservername__
+supports several mechanisms for supplying/obtaining configuration and
+run-time parameters: command line options, environment variables, the
+__xconfigfile__(__filemansuffix__) configuration files, auto-detection, and
+fallback defaults.  When the same information is supplied in more than
+one way, the highest precedence mechanism is used.  The list of mechanisms
+is ordered from highest precedence to lowest.  Note that not all parameters
+can be supplied via all methods.  The available command line options
+and environment variables (and some defaults) are described here and in
+the Xserver(__appmansuffix__) manual page.  Most configuration file
+parameters, with their defaults, are described in the
+__xconfigfile__(__filemansuffix__) manual page.  Driver and module specific
+configuration parameters are described in the relevant driver or module
+manual page.
+.PP
+In addition to the normal server options described in the
+Xserver(__appmansuffix__) manual page,
+.B __xservername__
+accepts the following command line switches:
+.TP 8
+.BI vt XX
+.I XX
+specifies the Virtual Terminal device number which
+.B __xservername__
+will use.  Without this option,
+.B __xservername__
+will pick the first available Virtual Terminal that it can locate.  This
+option applies only to platforms that have virtual terminal support, such
+as Linux, BSD, OpenSolaris, SVR3, and SVR4.
+.TP
+.B \-allowMouseOpenFail
+Allow the server to start up even if the mouse device can't be opened
+or initialised.  This is equivalent to the
+.B AllowMouseOpenFail
+__xconfigfile__(__filemansuffix__) file option.
+.TP 8
+.B \-allowNonLocalXvidtune
+Make the VidMode extension available to remote clients.  This allows
+the xvidtune client to connect from another host.  This is equivalent
+to the
+.B AllowNonLocalXvidtune
+__xconfigfile__(__filemansuffix__) file option.  By default non-local
+connections are not allowed.
+.TP 8
+.BI \-bgamma " value"
+Set the blue gamma correction.
+.I value
+must be between 0.1 and 10.
+The default is 1.0.  Not all drivers support this.  See also the
+.BR \-gamma ,
+.BR \-rgamma ,
+and
+.B \-ggamma
+options.
+.TP 8
+.BI \-bpp " n"
+No longer supported.  Use
+.B \-depth
+to set the color depth, and use
+.B \-fbbpp
+if you really need to force a non-default framebuffer (hardware) pixel
+format.
+.TP 8
+.BI \-config " file"
+Read the server configuration from
+.IR file .
+This option will work for any file when the server is run as root (i.e,
+with real-uid 0), or for files relative to a directory in the config
+search path for all other users.
+.TP 8
+.BI \-configdir " directory"
+Read the server configuration files from
+.IR directory .
+This option will work for any directory when the server is run as root
+(i.e, with real-uid 0), or for directories relative to a directory in the
+config directory search path for all other users.
+.TP 8
+.B \-configure
+When this option is specified, the
+.B __xservername__
+server loads all video driver modules, probes for available hardware,
+and writes out an initial __xconfigfile__(__filemansuffix__) file based on
+what was detected.  This option currently has some problems on some
+platforms, but in most cases it is a good way to bootstrap the
+configuration process.  This option is only available when the server
+is run as root (i.e, with real-uid 0).
+.TP 8
+.BI "\-crt /dev/tty" XX
+SCO only.  This is the same as the
+.B vt
+option, and is provided for compatibility with the native SCO X server.
+.TP 8
+.BI \-depth " n"
+Sets the default color depth.  Legal values are 1, 4, 8, 15, 16, and
+24.  Not all drivers support all values.
+.TP 8
+.B \-disableVidMode
+Disable the parts of the VidMode extension (used by the xvidtune
+client) that can be used to change the video modes.  This is equivalent
+to the
+.B DisableVidModeExtension
+__xconfigfile__(__filemansuffix__) file option.
+.TP 8
+.B \-fbbpp \fIn\fP
+Sets the number of framebuffer bits per pixel.  You should only set this
+if you're sure it's necessary; normally the server can deduce the correct
+value from
+.B \-depth
+above.  Useful if you want to run a depth 24 configuration with a 24
+bpp framebuffer rather than the (possibly default) 32 bpp framebuffer
+(or vice versa).  Legal values are 1, 8, 16, 24, 32.  Not all drivers
+support all values.
+.TP 8
+.B \-flipPixels
+Swap the default values for the black and white pixels.
+.TP 8
+.BI \-gamma " value"
+Set the gamma correction.
+.I value
+must be between 0.1 and 10.  The default is 1.0.  This value is applied
+equally to the R, G and B values.  Those values can be set independently
+with the
+.BR \-rgamma ,
+.BR \-bgamma ,
+and
+.B \-ggamma
+options.  Not all drivers support this.
+.TP 8
+.BI \-ggamma " value"
+Set the green gamma correction.
+.I value
+must be between 0.1 and 10.  The default is 1.0.  Not all drivers support
+this.  See also the
+.BR \-gamma ,
+.BR \-rgamma ,
+and
+.B \-bgamma
+options.
+.TP 8
+.B \-ignoreABI
+The
+.B __xservername__
+server checks the ABI revision levels of each module that it loads.  It
+will normally refuse to load modules with ABI revisions that are newer
+than the server's.  This is because such modules might use interfaces
+that the server does not have.  When this option is specified, mismatches
+like this are downgraded from fatal errors to warnings.  This option
+should be used with care.
+.TP 8
+.B \-isolateDevice \fIbus\-id\fP
+Restrict device resets to the device at
+.IR bus\-id .
+The
+.I bus\-id
+string has the form
+.IB bustype : bus : device : function
+(e.g., \(oqPCI:1:0:0\(cq).
+At present, only isolation of PCI devices is supported; i.e., this option
+is ignored if
+.I bustype
+is anything other than \(oqPCI\(cq.
+.TP 8
+.B \-keeptty
+Prevent the server from detaching its initial controlling terminal.
+This option is only useful when debugging the server.  Not all platforms
+support (or can use) this option.
+.TP 8
+.BI \-keyboard " keyboard-name"
+Use the __xconfigfile__(__filemansuffix__) file
+.B InputDevice
+section called
+.I keyboard-name
+as the core keyboard.  This option is ignored when the
+.B Layout
+section specifies a core keyboard.  In the absence of both a Layout
+section and this option, the first relevant
+.B InputDevice
+section is used for the core keyboard.
+.TP 8
+.BI \-layout " layout-name"
+Use the __xconfigfile__(__filemansuffix__) file
+.B Layout
+section called
+.IR layout-name .
+By default the first
+.B Layout
+section is used.
+.TP 8
+.BI \-logfile " filename"
+Use the file called
+.I filename
+as the
+.B __xservername__
+server log file.  The default log file is
+.BI __logdir__/__xservername__. n .log
+on most platforms, where
+.I n
+is the display number of the
+.B __xservername__
+server.  The default may be in a different directory on some platforms.
+This option is only available when the server is run as root (i.e, with
+real-uid 0).
+.TP 8
+.BR \-logverbose " [\fIn\fP]"
+Sets the verbosity level for information printed to the
+.B __xservername__
+server log file.  If the
+.I n
+value isn't supplied, each occurrence of this option increments the log
+file verbosity level.  When the
+.I n
+value is supplied, the log file verbosity level is set to that value.
+The default log file verbosity level is 3.
+.TP 8
+.BI \-modulepath " searchpath"
+Set the module search path to
+.IR searchpath .
+.I searchpath
+is a comma separated list of directories to search for
+.B __xservername__
+server modules.  This option is only available when the server is run
+as root (i.e, with real-uid 0).
+.TP 8
+.B \-nosilk
+Disable Silken Mouse support.
+.TP 8
+.B \-pixmap24
+Set the internal pixmap format for depth 24 pixmaps to 24 bits per pixel.
+The default is usually 32 bits per pixel.  There is normally little
+reason to use this option.  Some client applications don't like this
+pixmap format, even though it is a perfectly legal format.  This is
+equivalent to the
+.B Pixmap
+__xconfigfile__(__filemansuffix__) file option.
+.TP 8
+.B \-pixmap32
+Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel.
+This is usually the default.  This is equivalent to the
+.B Pixmap
+__xconfigfile__(__filemansuffix__) file option.
+.TP 8
+.BI \-pointer " pointer-name"
+Use the __xconfigfile__(__filemansuffix__) file
+.B InputDevice
+section called
+.I pointer-name
+as the core pointer.  This option is ignored when the
+.B Layout
+section specifies a core pointer.  In the absence of both a Layout
+section and this option, the first relevant
+.B InputDevice
+section is used for the core pointer.
+.TP 8
+.B \-quiet
+Suppress most informational messages at startup.  The verbosity level
+is set to zero.
+.TP 8
+.BI \-rgamma " value"
+Set the red gamma correction.
+.I value
+must be between 0.1 and 10.  The default is 1.0.  Not all drivers support
+this.  See also the
+.BR \-gamma ,
+.BR \-bgamma ,
+and
+.B \-ggamma
+options.
+.TP 8
+.BI \-screen " screen-name"
+Use the __xconfigfile__(__filemansuffix__) file
+.B Screen
+section called
+.IR screen-name .
+By default the screens referenced by the default
+.B Layout
+section are used, or the first
+.B Screen
+section when there are no
+.B Layout
+sections.
+.TP 8
+.B \-showconfig
+This is the same as the
+.B \-version
+option, and is included for compatibility reasons.  It may be removed
+in a future release, so the
+.B \-version
+option should be used instead.
+.TP 8
+.B \-showDefaultModulePath
+Print out the default module path the server was compiled with.
+.TP 8
+.B \-showDefaultLibPath
+Print out the path libraries should be installed to.
+.TP 8
+.B \-showopts
+For each driver module installed, print out the list of options and their
+argument types.
+.TP 8
+.BI \-weight " nnn"
+Set RGB weighting at 16 bpp.  The default is 565.  This applies only to
+those drivers which support 16 bpp.
+.TP 8
+.BR \-verbose " [\fIn\fP]"
+Sets the verbosity level for information printed on stderr.  If the
+.I n
+value isn't supplied, each occurrence of this option increments the
+verbosity level.  When the
+.I n
+value is supplied, the verbosity level is set to that value.  The default
+verbosity level is 0.
+.TP 8
+.B \-version
+Print out the server version, patchlevel, release date, the operating
+system/platform it was built on, and whether it includes module loader
+support.
+.SH "KEYBOARD"
+.PP
+The
+.B __xservername__
+server is normally configured to recognize various special combinations
+of key presses that instruct the server to perform some action, rather
+than just sending the key press event to a client application. These actions
+depend on the XKB keymap loaded by a particular keyboard device and may or
+may not be available on a given configuration.
+.PP
+The following key combinations are commonly part of the default XKEYBOARD
+keymap.
+.TP 8
+.B Ctrl+Alt+Backspace
+Immediately kills the server -- no questions asked. It can be disabled by
+setting the
+.B DontZap
+__xconfigfile__(__filemansuffix__) file option to a TRUE value.
+.PP
+.RS 8
+It should be noted that zapping is triggered by the
+.B Terminate_Server
+action in the keyboard map. This action is not part of the default keymaps
+but can be enabled with the XKB option
+.B \*qterminate:ctrl_alt_bksp\*q.
+.RE
+.TP 8
+.B Ctrl+Alt+Keypad-Plus
+Change video mode to next one specified in the configuration file.
+This can be disabled with the
+.B DontZoom
+__xconfigfile__(__filemansuffix__) file option.
+.TP 8
+.B Ctrl+Alt+Keypad-Minus
+Change video mode to previous one specified in the configuration file.
+This can be disabled with the
+.B DontZoom
+__xconfigfile__(__filemansuffix__) file option.
+.TP 8
+.B Ctrl+Alt+F1...F12
+For systems with virtual terminal support, these keystroke
+combinations are used to switch to virtual terminals 1 through 12,
+respectively.  This can be disabled with the
+.B DontVTSwitch
+__xconfigfile__(__filemansuffix__) file option.
+.SH CONFIGURATION
+.B __xservername__
+typically uses a configuration file called
+.B __xconfigfile__
+and configuration files with the suffix
+.I .conf
+in a directory called
+.B __xconfigdir__
+for its initial setup.
+Refer to the __xconfigfile__(__filemansuffix__) manual page for information
+about the format of this file.
+.PP
+.B __xservername__
+has a mechanism for automatically generating a built-in configuration
+at run-time when no
+.B __xconfigfile__
+file or
+.B __xconfigdir__
+files are present.  The current version of this automatic configuration
+mechanism works in two ways.
+.PP
+The first is via enhancements that have made many components of the
+.B __xconfigfile__
+file optional.  This means that information that can be probed or
+reasonably deduced doesn't need to be specified explicitly, greatly
+reducing the amount of built-in configuration information that needs to
+be generated at run-time.
+.PP
+The second is to have "safe" fallbacks for most configuration information.
+This maximises the likelihood that the
+.B __xservername__
+server will start up in some usable configuration even when information
+about the specific hardware is not available.
+.PP
+The automatic configuration support for __xservername__ is work in progress.
+It is currently aimed at the most popular hardware and software platforms
+supported by __xservername__.  Enhancements are planned for future releases.
+.SH FILES
+The
+.B __xservername__
+server config files can be found in a range of locations.  These are
+documented fully in the __xconfigfile__(__filemansuffix__) manual page.  The
+most commonly used locations are shown here.

+.SH NAME
+__xconfigfile__ and __xconfigdir__ \- configuration files for
+__xservername__ X server
+.SH INTRODUCTION
+.B __xservername__
+supports several mechanisms for supplying/obtaining configuration and
+run-time parameters: command line options, environment variables, the
+__xconfigfile__ and __xconfigdir__ configuration files, auto-detection,
+and fallback defaults. When the same information is supplied in more
+than one way, the highest precedence mechanism is used. The list of
+mechanisms is ordered from highest precedence to lowest. Note that not
+all parameters can be supplied via all methods. The available command
+line options and environment variables (and some defaults) are
+described in the Xserver(__appmansuffix__) and
+__xservername__(__appmansuffix__) manual pages. Most configuration file
+parameters, with their defaults, are described below. Driver and module
+specific configuration parameters are described in the relevant driver
+or module manual page.
+.SH DESCRIPTION
+.B __xservername__
+uses a configuration file called
+.I __xconfigfile__
+and files ending in the suffix
+.I .conf
+from the directory
+.I __xconfigdir__
+for its initial setup.
+The
+.I __xconfigfile__
+configuration file is searched for in the following places when the
+server is started as a normal user:
+.PP
+.RS 4
+.nf
+.IR /etc/X11/ <cmdline>
+.IR __projectroot__/etc/X11/ <cmdline>
+.IB /etc/X11/ $XORGCONFIG

+.IR __projectroot__/lib/X11/__xconfigfile__. <hostname>
+.I __projectroot__/lib/X11/__xconfigfile__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+is a relative path (with no \(lq..\(rq components) specified with the
+.B \-config
+command line option,
+.B $XORGCONFIG
+is the relative path (with no \(lq..\(rq components) specified by that
+environment variable, and
+.I <hostname>
+is the machine's hostname as reported by
+.BR gethostname (__libmansuffix__).
+.PP
+When the __xservername__ server is started by the \(lqroot\(rq user, the config file
+search locations are as follows:
+.PP
+.RS 4
+.nf
+<cmdline>
+.IR /etc/X11/ <cmdline>
+.IR __projectroot__/etc/X11/ <cmdline>

+.IR __projectroot__/lib/X11/__xconfigfile__. <hostname>
+.I __projectroot__/lib/X11/__xconfigfile__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+is the path specified with the
+.B \-config
+command line option (which may be absolute or relative),
+.B $XORGCONFIG
+is the path specified by that
+environment variable (absolute or relative),
+.B $HOME
+is the path specified by that environment variable (usually the home
+directory), and
+.I <hostname>
+is the machine's hostname as reported by
+.BR gethostname (__libmansuffix__).
+.PP
+Additional configuration files are searched for in the following
+directories when the server is started as a normal user:
+.PP
+.RS 4
+.nf
+.IR /etc/X11/ <cmdline>
+.IR __sysconfdir__/X11/ <cmdline>
+.I /etc/X11/__xconfigdir__
+.I __sysconfdir__/X11/__xconfigdir__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+is a relative path (with no \(lq..\(rq components) specified with the
+.B \-configdir
+command line option.
+.PP
+When the __xservername__ server is started by the \(lqroot\(rq user, the
+config directory search locations are as follows:
+.PP
+.RS 4
+.nf
+<cmdline>
+.IR /etc/X11/ <cmdline>
+.IR __sysconfdir__/X11/ <cmdline>
+.I /etc/X11/__xconfigdir__
+.I __sysconfdir__/X11/__xconfigdir__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+is the path specified with the
+.B \-configdir
+command line option (which may be absolute or relative).
+.PP
+Finally, configuration files will also be searched for in directories
+reserved for system use. These are to separate configuration files from
+the vendor or 3rd party packages from those of local administration.
+These files are found in the following directories:
+.PP
+.RS 4
+.nf
+.I /usr/share/X11/__xconfigdir__
+.I __datadir__/X11/__xconfigdir__
+.fi
+.RE
+.PP
+The
+.I __xconfigfile__
+and
+.I __xconfigdir__
+files are composed of a number of sections which may be present in any order,
+or omitted to use default configuration values.
+Each section has the form:
+.PP
+.RS 4
+.nf
+.BI "Section  \*q" SectionName \*q
+.RI "    " SectionEntry
+    ...
+.B EndSection
+.fi
+.RE
+.PP
+The section names are:
+.PP
+.RS 4

+section should be used instead.
+.PP
+.RS 4
+.nf
+.BR "Keyboard       " "Keyboard configuration"
+.BR "Pointer        " "Pointer/mouse configuration"
+.fi
+.RE
+.PP
+The old
+.B XInput
+section is no longer recognised.
+.PP
+The
+.B ServerLayout
+sections are at the highest level.
+They bind together the input and output devices that will be used in a session.
+The input devices are described in the
+.B InputDevice
+sections.
+Output devices usually consist of multiple independent components (e.g.,
+a graphics board and a monitor).
+These multiple components are bound together in the
+.B Screen
+sections, and it is these that are referenced by the
+.B ServerLayout
+section.
+Each
+.B Screen
+section binds together a graphics board and a monitor.
+The graphics boards are described in the
+.B Device
+sections, and the monitors are described in the
+.B Monitor
+sections.
+.PP
+Config file keywords are case\-insensitive, and \(lq_\(rq characters are
+ignored.
+Most strings (including
+.B Option
+names) are also case-insensitive, and insensitive to white space and
+\(lq_\(rq characters.
+.PP
+Each config file entry usually takes up a single line in the file.  They
+consist of a keyword, which is possibly followed by one or more arguments,
+with the number and types of the arguments depending on the keyword.
+The argument types are:
+.PP
+.RS 4
+.nf
+.BR "Integer     " "an integer number in decimal, hex or octal"
+.BR "Real        " "a floating point number"
+.BR "String      " "a string enclosed in double quote marks (\*q)"
+.fi
+.RE
+.PP
+Note: hex integer values must be prefixed with \(lq0x\(rq, and octal values
+with \(lq0\(rq.
+.PP
+A special keyword called
+.B Option
+may be used to provide free\-form data to various components of the server.
+The
+.B Option
+keyword takes either one or two string arguments.
+The first is the option name, and the optional second argument is the
+option value.
+Some commonly used option value types include:
+.PP
+.RS 4
+.nf
+.BR "Integer     " "an integer number in decimal, hex or octal"
+.BR "Real        " "a floating point number"
+.BR "String      " "a sequence of characters"
+.BR "Boolean     " "a boolean value (see below)"
+.BR "Frequency   " "a frequency value (see below)"
+.fi
+.RE
+.PP
+Note that
+.I all
+.B Option
+values, not just strings, must be enclosed in quotes.
+.PP
+Boolean options may optionally have a value specified.
+When no value is specified, the option's value is
+.BR TRUE .
+The following boolean option values are recognised as
+.BR TRUE :
+.PP
+.RS 4
+.BR 1 ,
+.BR on ,
+.BR true ,
+.B yes
+.RE
+.PP
+and the following boolean option values are recognised as
+.BR FALSE :
+.PP
+.RS 4
+.BR 0 ,
+.BR off ,
+.BR false ,
+.B no
+.RE
+.PP
+If an option name is prefixed with
+.RB \*q No \*q,
+then the option value is negated.
+.PP
+Example: the following option entries are equivalent:
+.PP
+.RS 4
+.nf
+.B "Option \*qAccel\*q   \*qOff\*q"
+.B "Option \*qNoAccel\*q"
+.B "Option \*qNoAccel\*q \*qOn\*q"
+.B "Option \*qAccel\*q   \*qfalse\*q"
+.B "Option \*qAccel\*q   \*qno\*q"
+.fi
+.RE
+.PP
+Frequency option values consist of a real number that is optionally
+followed by one of the following frequency units:
+.PP
+.RS 4
+.BR Hz ,
+.BR k ,
+.BR kHz ,
+.BR M ,
+.B MHz
+.RE
+.PP
+When the unit name is omitted, the correct units will be determined from
+the value and the expectations of the appropriate range of the value.
+It is recommended that the units always be specified when using frequency
+option values to avoid any errors in determining the value.
+.SH "FILES SECTION"
+The
+.B Files
+section is used to specify some path names required by the server.
+Some of these paths can also be set from the command line (see
+.BR Xserver (__appmansuffix__)
+and

+The command line settings override the values specified in the config
+file.

+.SH "SERVERFLAGS SECTION"
+In addition to options specific to this section (described below), the
+.B ServerFlags
+section is used to specify some global
+__xservername__ server options.
+All of the entries in this section are
+.BR Options ,
+although for compatibility purposes some of the old style entries are
+still recognised.
+Those old style entries are not documented here, and using them is
+discouraged.
+The
+.B ServerFlags
+section is optional, as are the entries that may be specified in it.
+.PP
+.B Options
+specified in this section (with the exception of the
+.B \*qDefaultServerLayout\*q
+.BR Option )
+may be overridden by
+.B Options
+specified in the active
+.B ServerLayout
+section.
+Options with command line equivalents are overridden when their command
+line equivalent is used.
+The options recognised by this section are:
+.TP 7
+.BI "Option \*qDefaultServerLayout\*q  \*q" layout\-id \*q
+This specifies the default
+.B ServerLayout
+section to use in the absence of the
+.B \-layout
+command line option.
+.TP 7
+.BI "Option \*qNoTrapSignals\*q  \*q" boolean \*q
+This prevents the __xservername__ server from trapping a range of unexpected fatal
+signals and exiting cleanly.
+Instead, the __xservername__ server will die and drop core where the fault occurred.
+The default behaviour is for the __xservername__ server to exit cleanly, but still drop a
+core file.
+In general you never want to use this option unless you are debugging an __xservername__
+server problem and know how to deal with the consequences.
+.TP 7
+.BI "Option \*qUseSIGIO\*q  \*q" boolean \*q
+This controls whether the __xservername__ server requests that events from
+input devices be reported via a SIGIO signal handler (also known as SIGPOLL
+on some platforms), or only reported via the standard select(3) loop.
+The default behaviour is platform specific.   In general you do not want to
+use this option unless you are debugging the __xservername__ server, or
+working around a specific bug until it is fixed, and understand the
+consequences.
+.TP 7
+.BI "Option \*qDontVTSwitch\*q  \*q" boolean \*q
+This disallows the use of the
+.BI Ctrl+Alt+F n
+sequence (where
+.RI F n
+refers to one of the numbered function keys).
+That sequence is normally used to switch to another \*qvirtual terminal\*q
+on operating systems that have this feature.
+When this option is enabled, that key sequence has no special meaning and
+is passed to clients.
+Default: off.
+.TP 7
+.BI "Option \*qDontZap\*q  \*q" boolean \*q
+This disallows the use of the
+.B Terminate_Server
+XKB action (usually on Ctrl+Alt+Backspace, depending on XKB options).
+This action is normally used to terminate the __xservername__ server.
+When this option is enabled, the action has no effect.
+Default: off.
+.TP 7
+.BI "Option \*qDontZoom\*q  \*q" boolean \*q
+This disallows the use of the
+.B Ctrl+Alt+Keypad\-Plus
+and
+.B Ctrl+Alt+Keypad\-Minus
+sequences.
+These sequences allows you to switch between video modes.
+When this option is enabled, those key sequences have no special meaning
+and are passed to clients.
+Default: off.
+.TP 7
+.BI "Option \*qDisableVidModeExtension\*q  \*q" boolean \*q
+This disables the parts of the VidMode extension used by the xvidtune client
+that can be used to change the video modes.
+Default: the VidMode extension is enabled.
+.TP 7
+.BI "Option \*qAllowNonLocalXvidtune\*q  \*q" boolean \*q
+This allows the xvidtune client (and other clients that use the VidMode
+extension) to connect from another host.
+Default: off.
+.TP 7
+.BI "Option \*qAllowMouseOpenFail\*q  \*q" boolean \*q
+This tells the mousedrv(__drivermansuffix__) and vmmouse(__drivermansuffix__)
+drivers to not report failure if the mouse device can't be opened/initialised.
+It has no effect on the evdev(__drivermansuffix__) or other drivers.
+Default: false.
+.TP 7
+.BI "Option \*qVTSysReq\*q  \*q" boolean \*q
+enables the SYSV\-style VT switch sequence for non\-SYSV systems
+which support VT switching.
+This sequence is
+.B Alt\-SysRq
+followed by a function key
+.RB ( Fn ).
+This prevents the __xservername__ server trapping the
+keys used for the default VT switch sequence, which means that clients can
+access them.
+Default: off.
+.TP 7
+.BI "Option \*qBlankTime\*q  \*q" time \*q
+sets the inactivity timeout for the
+.B blank
+phase of the screensaver.
+.I time
+is in minutes.
+This is equivalent to the __xservername__ server's
+.B \-s
+flag, and the value can be changed at run\-time with
+.BR xset(__appmansuffix__).
+Default: 10 minutes.
+.TP 7
+.BI "Option \*qStandbyTime\*q  \*q" time \*q
+sets the inactivity timeout for the
+.B standby
+phase of DPMS mode.
+.I time
+is in minutes, and the value can be changed at run\-time with
+.BR xset(__appmansuffix__).
+Default: 10 minutes.

+.SH "MODULE SECTION"
+The
+.B Module
+section is used to specify which __xservername__ server modules should be loaded.
+This section is ignored when the __xservername__ server is built in static form.
+The type of modules normally loaded in this section are __xservername__ server
+extension modules.
+Most other module types are loaded automatically when they are needed via
+other mechanisms.
+The
+.B Module
+section is optional, as are all of the entries that may be specified in
+it.
+.PP
+Entries in this section may be in two forms.
+The first and most commonly used form is an entry that uses the
+.B Load
+keyword, as described here:
+.TP 7
+.BI "Load  \*q" modulename \*q
+This instructs the server to load the module called
+.IR modulename .
+The module name given should be the module's standard name, not the
+module file name.
+The standard name is case\-sensitive, and does not include the \(lqlib\(rq
+prefix, or the \(lq.a\(rq, \(lq.o\(rq, or \(lq.so\(rq suffixes.
+.PP
+.RS 7
+Example: the DRI extension module can be loaded with the following entry:
+.PP
+.RS 4
+.B "Load \*qdri\*q"
+.RE
+.RE
+.TP 7
+.BI "Disable  \*q" modulename \*q
+This instructs the server to not load the module called
+.IR modulename .
+Some modules are loaded by default in the server, and this overrides that
+default. If a
+.B Load
+instruction is given for the same module, it overrides the
+.B Disable
+instruction and the module is loaded. The module name given should be the
+module's standard name, not the module file name. As with the
+.B Load
+instruction, the standard name is case-sensitive, and does not include the
+"lib" prefix, or the ".a", ".o", or ".so" suffixes.
+.PP
+The second form of entry is a
+.BR SubSection,
+with the subsection name being the module name, and the contents of the
+.B SubSection
+being
+.B Options
+that are passed to the module when it is loaded.
+.PP
+Example: the extmod module (which contains a miscellaneous group of
+server extensions) can be loaded, with the XFree86\-DGA extension
+disabled by using the following entry:
+.PP
+.RS 4
+.nf
+.B "SubSection \*qextmod\*q"
+.B "   Option  \*qomit XFree86\-DGA\*q"
+.B EndSubSection
+.fi
+.RE
+.PP
+Modules are searched for in each directory specified in the
+.B ModulePath
+search path, and in the drivers, extensions, input, internal, and
+multimedia subdirectories of each of those directories.
+In addition to this, operating system specific subdirectories of all
+the above are searched first if they exist.
+.PP
+To see what extension modules are available, check the extensions
+subdirectory under:
+.PP
+.RS 4
+.nf
+__modulepath__
+.fi
+.RE
+.PP
+The \(lqextmod\(rq, \(lqdbe\(rq, \(lqdri\(rq, \(lqdri2\(rq, \(lqglx\(rq,
+and \(lqrecord\(rq extension modules are loaded automatically, if they
+are present, unless disabled with \*qDisable\*q entries.
+It is recommended
+that at very least the \(lqextmod\(rq extension module be loaded.
+If it isn't, some commonly used server extensions (like the SHAPE
+extension) will not be available.
+.SH "EXTENSIONS SECTION"
+The
+.B Extensions
+section is used to specify which X11 protocol extensions should be enabled
+or disabled.
+The
+.B Extensions
+section is optional, as are all of the entries that may be specified in
+it.
+.PP
+Entries in this section are listed as Option statements with the name of
+the extension as the first argument, and a boolean value as the second.
+The extension name is case\-sensitive, and matches the form shown in the output
+of \*qXorg -extension ?\*q.
+.PP
+.RS 7
+Example: the MIT-SHM extension can be disabled with the following entry:
+.PP
+.RS 4
+.nf

+.RE
+.RE
+.SH "INPUTDEVICE SECTION"
+The config file may have multiple
+.B InputDevice
+sections.
+Recent X servers employ HAL or udev backends for input device enumeration
+and input hotplugging. It is usually not
+necessary to provide
+.B InputDevice
+sections in the xorg.conf if hotplugging is in use. If hotplugging is
+enabled,
+.B InputDevice
+sections using the
+.B mouse, kbd
+and
+.B vmmouse
+driver will be ignored.
+.PP
+If hotplugging is disabled, there will normally
+be at least two: one for the core (primary) keyboard
+and one for the core pointer.
+If either of these two is missing, a default configuration for the missing
+ones will be used. In the absence of an explicitly specified core input
+device, the first
+.B InputDevice
+marked as
+.B CorePointer
+(or
+.BR CoreKeyboard )
+is used.
+If there is no match there, the first
+.B InputDevice
+that uses the \(lqmouse\(rq (or \(lqkbd\(rq) driver is used.
+The final fallback is to use built\-in default configurations.
+Currently the default configuration may not work as expected on all platforms.

+the most important acceleration options are discussed here.
+.TP 7
+.BI "Option \*qAccelerationProfile\*q  \*q" integer \*q
+Select the profile. In layman's terms, the profile constitutes the "feeling" of

+acceleration as a function of current device velocity and acceleration controls)
+is constructed. This is mainly a matter of personal preference.

+factor is a rational which, together with threshold, can be used to tweak
+profiles to suit the users needs. The
+.B simple
+and
+.B limited
+profiles use it directly (i.e. they accelerate by the factor), for other
+profiles it should hold that a higher acceleration factor leads to a faster

+.SH "SERVERLAYOUT SECTION"
+The config file may have multiple
+.B ServerLayout
+sections.
+A \(lqserver layout\(rq represents the binding of one or more screens
+.RB ( Screen
+sections) and one or more input devices
+.RB ( InputDevice
+sections) to form a complete configuration.
+In multi\-head configurations, it also specifies the relative layout of the

+section (the former takes precedence over the latter).
+If those options are not used, the first
+.B ServerLayout
+section found in the config file is considered the active one.
+If no
+.B ServerLayout
+sections are present, the single active screen and two active (core)
+input devices are selected as described in the relevant sections above.

+The entries that may be used in this section are described here.
+.TP 7
+.BI "Screen  " "screen\-num" " \*qscreen\-id\*q " "position\-information"
+One of these entries must be given for each screen being used in
+a session.

+field is mandatory, and specifies the
+.B Screen
+section being referenced.
+The
+.I screen\-num
+field is optional, and may be used to specify the screen number
+in multi\-head configurations.
+When this field is omitted, the screens will be numbered in the order that
+they are listed in.
+The numbering starts from 0, and must be consecutive.
+The

+.TP 4
+.BI "Absolute  " "x y"
+These both specify that the upper left corner's coordinates are
+.RI ( x , y ).
+The
+.B Absolute
+keyword is optional.
+Some older versions of XFree86 (4.2 and earlier) don't recognise the
+.B Absolute
+keyword, so it's safest to just specify the coordinates without it.

+The first four position the screen immediately to the right, left, above or
+below the other screen.
+When positioning to the right or left, the top edges are aligned.
+When positioning above or below, the left edges are aligned.
+The
+.B Relative

+relative to the origin of another screen.
+.RE
+.TP 7
+.BI "InputDevice  \*q" idev\-id "\*q \*q" option \*q " ..."
+One of these entries should be given for each input device being used in
+a session.
+Normally at least two are required, one each for the core pointer and
+keyboard devices.
+If either of those is missing, suitable
+.B InputDevice
+entries are searched for using the method described above in the
+.B INPUTDEVICE
+section.  The
+.I idev\-id
+field is mandatory, and specifies the name of the
+.B InputDevice
+section being referenced.
+Multiple
+.I option
+fields may be specified, each in double quotes.
+The options permitted here are any that may also be given in the

+    <title>Preface</title>
+
+    <para>
+This document was originally the design spec for the DDX layer of the
+XFree86 4.0 X server.  The X.Org Foundation adopted the XFree86 4.4rc2
+version of that server as the basis of the Xorg server project, and has
+evolved the XFree86 DDX layer greatly since forking.   This document thus
+covers only the current implementation of the XFree86 DDX as found in the
+Xorg server &xserver.version; release, and no longer matches the XFree86
+server itself.

+While the XFree86 project had a goal of avoiding changes to the DIX
+layer unless they found major deficiencies there, to avoid divergence from
+the X.Org sample implementation they were integrating changes from, the
+X.Org developers now maintain both sides, and make changes where they are
+most appropriate.   This document concentrates on the XFree86 DDX layer used
+in the Xorg server itself (the code found in <filename>hw/xfree86</filename>
+in the source tree), and developers will also want to refer to the
+<filename>Xserver-spec</filename> documentation that covers the DIX layer
+routines common to all the X servers in the sample implementation.

+    <title>The xorg.conf File</title>
+
+    <para>
+The xorg.conf file format is based on the XF86Config format from XFree86 4.4,
+which is in turn similar to the old XFree86 3.x XF86Config format, with the
+following changes:
+    </para>
+
+    <sect2>
+      <title>&k.device; section</title>
+
+      <para>
+    The &k.device; sections are similar to what they used to be, and
+    describe hardware-specific information for a single video card.
+    &k.device;
+    Some new keywords are added:
+
+
+	<variablelist>
+	  <varlistentry><term>Driver "drivername"</term>
+	    <listitem><para>
+        Specifies the name of the driver to be used for the card.  This
+        is mandatory.
+	      </para></listitem></varlistentry>
+	  <varlistentry><term>BusID "busslot"</term>
+	    <listitem><para>
+        Specifies uniquely the location of the card on the bus.  The
+        purpose is to identify particular cards in a multi-headed
+        configuration.  The format of the argument is intentionally
+        vague, and may be architecture dependent.  For a PCI bus, it
+        is something like "bus:slot:func".
+	      </para></listitem></varlistentry>
+	</variablelist>
+      </para>
+
+      <para>
+    A &k.device; section is considered <quote>active</quote> if there is a reference
+    to it in an active &k.screen; section.
+      </para>
+    </sect2>
+
+    <sect2>
+      <title>&k.screen; section</title>
+
+      <para>
+    The &k.screen; sections are similar to what they used to be.  They
+    no longer have a &k.driver; keyword, but an &k.identifier; keyword
+    is added.  (The &k.driver; keyword may be accepted in place of the
+    &k.identifier; keyword for compatibility purposes.)  The identifier
+    can be used to identify which screen is to be active when multiple
+    &k.screen; sections are present.  It is possible to specify the active
+    screen from the command line.  A default is chosen in the absence
+    of one being specified.  A &k.screen; section is considered <quote>active</quote>
+    if there is a reference to it either from the command line, or from
+    an active &k.serverlayout; section.
+      </para>
+    </sect2>
+
+    <sect2>
+      <title>&k.inputdevice; section</title>
+
+      <para>
+    The &k.inputdevice; section is a new section that describes
+    configuration information for input devices.  It replaces the old
+    <emphasis>Keyboard</emphasis>, <emphasis>Pointer</emphasis> and <emphasis>XInput</emphasis>
+    sections.  Like the &k.device; section, it has two mandatory keywords:
+    &k.identifier; and &k.driver;.  For compatibility purposes the old
+    <emphasis>Keyboard</emphasis> and <emphasis>Pointer</emphasis> sections are
+    converted by the parser into &k.inputdevice; sections as follows:
+
+	<variablelist>
+	  <varlistentry><term><emphasis>Keyboard</emphasis></term>
+	    <listitem><literallayout>
+             &k.identifier; "Implicit Core Keyboard"
+             &k.driver; "keyboard"
+	      </literallayout></listitem></varlistentry>
+	  <varlistentry><term><emphasis>Pointer</emphasis></term>
+	    <listitem><literallayout>
+             &k.identifier; "Implicit Core Pointer"
+             &k.driver; "mouse"
+	      </literallayout></listitem></varlistentry>
+	</variablelist>
+      </para>
+
+      <para>
+    An &k.inputdevice; section is considered active if there is a
+    reference to it in an active &k.serverlayout; section.  An
+    &k.inputdevice; section may also be referenced implicitly if there
+    is no &k.serverlayout; section, if the <option>-screen</option> command
+    line options is used, or if the &k.serverlayout; section doesn't
+    reference any &k.inputdevice; sections.  In this case, the first
+    sections with drivers "keyboard" and "mouse" are used as the core
+    keyboard and pointer respectively.
+      </para>
+    </sect2>
+
+    <sect2>
+      <title>&k.serverlayout; section</title>
+
+      <para>
+    The &k.serverlayout; section is a new section that is used to identify
+    which &k.screen; sections are to be used in a multi-headed configuration,
+    and the relative layout of those screens.  It also identifies which
+    &k.inputdevice; sections are to be used.  Each &k.serverlayout; section
+    has an identifier, a list of &k.screen; section identifiers, and a list of
+    &k.inputdevice; section identifiers.  &k.serverflags; options may also be
+    included in a &k.serverlayout; section, making it possible to override
+    the global values in the &k.serverflags; section.
+      </para>
+
+      <para>
+    A &k.serverlayout; section can be made active by being referenced on
+    the command line.  In the absence of this, a default will be chosen
+    (the first one found).  The screen names may optionally be followed
+    by a number specifying the preferred screen number, and optionally
+    by information specifying the physical positioning of the screen,
+    either in absolute terms or relative to another screen (or screens).
+    When no screen number is specified, they are numbered according to
+    the order in which they are listed.  The old (now obsolete) method
+    of providing the positioning information is to give the names of
+    the four adjacent screens.  The order of these is top, bottom, left,
+    right.  Here is an example of a &k.serverlayout; section for two
+    screens using the old method, with the second located to the right
+    of the first:
+
+	<programlisting>
+      Section "ServerLayout"
+        Identifier "Main Layout"
+        Screen     0 "Screen 1" ""  ""  ""  "Screen 2"
+        Screen     1 "Screen 2"
+        Screen     "Screen 3"
+      EndSection
+	</programlisting>
+      </para>
+
+      <para>
+    The preferred way of specifying the layout is to explicitly specify
+    the screen's location in absolute terms or relative to another
+    screen.
+      </para>
+
+      <para>
+    In the absolute case, the upper left corner's coordinates are given
+    after the <emphasis>Absolute</emphasis> keyword.  If the coordinates are
+    omitted, a value of <code>(0,0)</code> is assumed.  An example
+    of absolute positioning follows:
+
+	<programlisting>
+      Section "ServerLayout"
+        Identifier "Main Layout"
+        Screen     0 "Screen 1" Absolute 0 0
+        Screen     1 "Screen 2" Absolute 1024 0
+        Screen     "Screen 3" Absolute 2048 0
+      EndSection
+	</programlisting>
+      </para>
+
+      <para>
+    In the relative case, the position is specified by either using one of
+    the following keywords followed by the name of the reference screen:
+
+	<simplelist type='vert' columns='1'>
+	  <member><emphasis>RightOf</emphasis></member>
+	  <member><emphasis>LeftOf</emphasis></member>
+	  <member><emphasis>Above</emphasis></member>
+	  <member><emphasis>Below</emphasis></member>
+	  <member><emphasis>Relative</emphasis></member>
+	</simplelist>
+      </para>

+    <title>Driver Interface</title>
+
+    <para>
+The driver interface consists of a minimal set of entry points that are
+required based on the external events that the driver must react to.
+No non-essential structure is imposed on the way they are used beyond
+that.  This is a significant difference compared with the old design.
+    </para>
+
+    <para>
+The entry points for drawing operations are already taken care of by
+the framebuffer code (including, XAA).  Extensions and enhancements to
+framebuffer code are outside the scope of this document.
+    </para>
+
+    <para>
+This approach to the driver interface provides good flexibility, but does
+increase the complexity of drivers.  To help address this, the XFree86
+common layer provides a set of <quote>helper</quote> functions to take care of things
+that most drivers need.  These helpers help minimise the amount of code
+duplication between drivers.  The use of helper functions by drivers is
+however optional, though encouraged.  The basic philosophy behind the
+helper functions is that they should be useful to many drivers, that
+they should balance this against the complexity of their interface.  It
+is inevitable that some drivers may find some helpers unsuitable and
+need to provide their own code.

+    <title>Resource Access Control Introduction</title>
+
+    <para>
+Graphics devices are accessed through ranges in I/O or memory space.
+While most modern graphics devices allow relocation of such ranges many
+of them still require the use of well established interfaces such as
+VGA memory and IO ranges or 8514/A IO ranges.  With modern buses (like
+PCI) it is possible for multiple video devices to share access to these
+resources.  The RAC (Resource Access Control) subsystem provides a
+mechanism for this.

+	<title>Bus</title>
+
+	<para>
+    <quote>Bus</quote> is ambiguous as it is used for different things: it may refer
+    to physical incompatible extension connectors in a computer system.
+    The RAC system knows two such systems: The ISA bus and the PCI bus.
+    (On the software level EISA, MCA and VL buses are currently treated
+    like ISA buses).  <quote>Bus</quote> may also refer to logically different
+    entities on a single bus system which are connected via bridges.  A
+    PCI system may have several distinct PCI buses connecting each other
+    by PCI-PCI bridges or to the host CPU by HOST-PCI bridges.
+	</para>
+
+	<para>
+    Systems that host more than one bus system link these together using
+    bridges.  Bridges are a concern to RAC as they might block or pass
+    specific resources.  PCI-PCI bridges may be set up to pass VGA
+    resources to the secondary bus.  PCI-ISA buses pass any resources not
+    decoded on the primary PCI bus to the ISA bus.  This way VGA resources
+    (although exclusive on the ISA bus) can be shared by ISA and PCI
+    cards.  Currently HOST-PCI bridges are not yet handled by RAC as they
+    require specific drivers.

+	<title>Entity</title>
+
+	<para>
+    The smallest independently addressable unit on a system bus is

+    entities can be located on the PCI bus by an unique ID consisting of
+    the bus, card and function number.

+    can decode.
+	</para>
+
+	<para>
+    If a device is capable of disabling this decoding the resource is
+    called sharable.  For PCI devices a generic method is provided to
+    control resource decoding.  Other devices will have to provide a
+    device specific function to control decoding.
+	</para>
+
+	<para>
+    If the entity is capable of decoding this range at a different

+    a mode change takes place or the server exits or does VT switching.
+    During this state all entity resources are under resource access
+    control.  During OPERATING state only those entities are controlled
+    which actually have shared resources that conflict with others.

+      It should be noted that many chipsets impose restrictions on where the

+      reasons, or to prevent the start of the viewport from being positioned
+      within a pixel (as can happen in a 24bpp mode).  After calculating the
+      value the chipset's panning registers need to be set to for non-DGA
+      modes, this function should recalculate the ScrnInfoRec's
+      <structfield>frameX0</structfield>, <structfield>frameY0</structfield>, <structfield>frameX1</structfield>
+      and <structfield>frameY1</structfield> fields to correspond to that value.  If
+      this is not done, switching to another mode might cause the position
+      of a hardware cursor to change.

+
+      <para>
+The screen-specific data collected from the config file is stored in

+The XFree86 common layer's screen specific data (the actual data in use

+time, and it is the responsibility of the Drivers' <function>Probe()</function>
+and <function>PreInit()</function> functions to finish filling them in based
+on both data provided on the command line and data provided from the
+Config file.  The precedence for this is:

+As well as containing screen-specific data that the XFree86 common layer
+(including essential parts of the server infrastructure as well as helper

+      <para>
+Per-screen driver specific data that cannot be accommodated with the
+static <structname>ScrnInfoRec</structname> fields is held in a driver-defined
+data structure, a pointer to which is assigned to the
+<structname>ScrnInfoRec</structname>'s <structfield>driverPrivate</structfield> field.  This
+is per-screen data that persists across server generations (as does the
+bulk of the static <structname>ScrnInfoRec</structname> data).  It would typically
+also include the video card's saved state.

+
+      <para>
+Per-screen data for other modules that the driver uses (for example,

+field.

+video drivers will be documented here.  In the meantime, those things
+defined in the <filename>xf86.h</filename> and <filename>xf86str.h</filename>
+files are visible to video drivers.  Things defined in

+The XFree86 common layer has knowledge of generic access control mechanisms
+for devices on certain bus systems (currently the PCI bus) as well as
+of methods to enable or disable access to the buses itself.  Furthermore
+it can access information on resources decoded by these devices and if
+necessary modify it.
+      </para>
+
+      <para>
+When first starting the Xserver collects all this information, saves it
+for restoration, checks it for consistency, and if necessary, corrects
+it.  Finally it disables all resources on a generic level prior to
+calling any driver function.
+      </para>
+
+      <para>
+When the <function>Probe()</function> function of each driver is called the
+device sections are matched against the devices found in the system.
+The driver may probe devices at this stage that cannot be identified by
+using device independent methods.  Access to all resources that can be
+controlled in a device independent way is disabled.  The
+<function>Probe()</function> function should register all non-relocatable
+resources at this stage.  If a resource conflict is found between
+exclusive resources the driver will fail immediately.  Optionally the
+driver might specify an <function>EntityInit()</function>,
+<function>EntityLeave()</function> and <function>EntityEnter()</function> function.
+      </para>
+
+      <para>
+<function>EntityInit()</function> can be used to disable any shared resources
+that are not controlled by the generic access control functions.  It is
+called prior to the PreInit phase regardless if an entity is active or
+not.  When calling the <function>EntityInit()</function>,
+<function>EntityEnter()</function> and <function>EntityLeave()</function> functions
+the common level will disable access to all other entities on a generic
+level.  Since the common level has no knowledge of device specific
+methods to disable access to resources it cannot be guaranteed that
+certain resources are not decoded by any other entity until the
+<function>EntityInit()</function> or <function>EntityEnter()</function> phase is
+finished.  Device drivers should therefore register all those resources
+which they are going to disable.  If these resources are never to be
+used by any driver function they may be flagged <constant>ResInit</constant>
+so that they can be removed from the resource list after processing all
+<function>EntityInit()</function> functions.  <function>EntityEnter()</function>
+should disable decoding of all resources which are not registered as
+exclusive and which are not handled by the generic access control in
+the common level.  The difference to <function>EntityInit()</function> is
+that the latter one is only called once during lifetime of the server.
+It can therefore be used to set up variables prior to disabling resources.
+<function>EntityLeave()</function> should restore the original state when
+exiting the server or switching to a different VT.  It also needs to
+disable device specific access functions if they need to be disabled on
+server exit or VT switch.  The default state is to enable them before
+giving up the VT.
+      </para>
+
+      <para>
+In <function>PreInit()</function> phase each driver should check if any
+sharable resources it has registered during <function>Probe()</function> has
+been denied and take appropriate action which could simply be to fail.
+If it needs to access resources it has disabled during
+<function>EntitySetup()</function> it can do so provided it has registered
+these and will disable them before returning from
+<function>PreInit()</function>.  This also applies to all other driver
+functions.  Several functions are provided to request resource ranges,
+register these, correct PCI config space and add replacements for the
+generic access functions.  Resources may be marked <quote>disabled</quote> or
+<quote>unused</quote> during OPERATING stage.  Although these steps could also be
+performed in <function>ScreenInit()</function>, this is not desirable.
+      </para>
+
+      <para>
+Following <function>PreInit()</function> phase the common level determines
+if resource access control is needed.  This is the case if more than
+one screen is used.  If necessary the RAC wrapper module is loaded.  In
+<function>ScreenInit()</function> the drivers can decide which operations
+need to be placed under RAC.  Available are the frame buffer operations,
+the pointer operations and the colormap operations.  Any operation that
+requires resources which might be disabled during OPERATING state should
+be set to use RAC.  This can be specified separately for memory and IO
+resources.
+      </para>
+
+      <para>
+When <function>ScreenInit()</function> phase is done the common level will
+determine which shared resources are requested by more than one driver
+and set the access functions accordingly.  This is done following these
+rules:
+
+	<orderedlist>
+	  <listitem><para>
+   The sharable resources registered by each entity are compared.  If
+   a resource is registered by more than one entity the entity will be
+   marked to need to share this resources type (<constant>IO</constant> or

+   OPERATING state.
+	    </para></listitem>
+
+	  <listitem><para>
+   If an <quote>unused</quote> resource was found to conflict however the entity
+   does not use any other resource of this type the entire resource type
+   will be disabled for that entity.
+	    </para></listitem>
+	</orderedlist>
+      </para>
+
+      <para>
+The driver has the choice among different ways to control access to
+certain resources:
+
+	<orderedlist>
+	  <listitem><para>
+   It can rely on the generic access functions.  This is probably the
+   most common case.  Here the driver only needs to register any resource

+
+	  <listitem><para>
+   It can replace the generic access functions by driver specific
+   ones.  This will mostly be used in cases where no generic access
+   functions are available.  In this case the driver has to make sure
+   these resources are disabled when entering the <function>PreInit()</function>
+   stage.  Since the replacement functions are registered in
+   <function>PreInit()</function> the driver will have to enable these
+   resources itself if it needs to access them during this state.  The
+   driver can specify if the replacement functions can control memory
+   and/or I/O resources separately.
+	    </para></listitem>
+
+	  <listitem><para>
+   The driver can enable resources itself when it needs them.  Each
+   driver function enabling them needs to disable them before it will
+   return.  This should be used if a resource which can be controlled
+   in a device dependent way is only required during SETUP state.  This
+   way it can be marked <quote>unused</quote> during OPERATING state.
+	    </para></listitem>
+	</orderedlist>

+
+      <para>
+A resource which is decoded during OPERATING state however never accessed

+      </para>
+
+      <para>
+Since access switching latencies are an issue during Xserver operation,
+the common level attempts to minimize the number of entities that need
+to be placed under RAC control.  When a wrapped operation is called,
+the <function>EnableAccess()</function> function is called before control is
+passed on.  <function>EnableAccess()</function> checks if a screen is under
+access control.  If not it just establishes bus routing and returns.
+If the screen needs to be under access control,
+<function>EnableAccess()</function> determines which resource types
+(<literal remap="tt">MEM</literal>, <literal remap="tt">IO</literal>) are required.  Then it tests
+if this access is already established.  If so it simply returns.  If
+not it disables the currently established access, fixes bus routing and
+enables access to all entities registered for this screen.

+The option entries are handled by the parser, and a list of the parsed
+options is included with each of the appropriate data structures that
+the drivers have access to.  The data structures used to hold the option
+information are opaque to the driver, and a driver must not access the
+option data directly.  Instead, the common layer provides a set of
+functions that may be used to access, check and manipulate the option
+data.

+layer by filling out one or more <literal remap="tt">XF86VideoAdaptorRecs</literal>

+<literal remap="tt">XF86VideoAdaptorPtr</literal> pointers to the following function:

+    <title>The Loader</title>
+
+    <para>
+This section describes the interfaces to the module loader.  The loader
+interfaces can be divided into two groups: those that are only available to
+the XFree86 common layer, and those that are also available to modules.
+    </para>
+
+    <sect2>
+      <title>Loader Overview</title>
+
+      <para>
+The loader is capable of loading modules in a range of object formats,
+and knowledge of these formats is built in to the loader.  Knowledge of
+new object formats can be added to the loader in a straightforward
+manner.  This makes it possible to provide OS-independent modules (for
+a given CPU architecture type).  In addition to this, the loader can
+load modules via the OS-provided <function>dlopen(3)</function> service where
+available.  Such modules are not platform independent, and the semantics
+of <function>dlopen()</function> on most systems results in significant
+limitations in the use of modules of this type.  Support for
+<function>dlopen()</function> modules in the loader is primarily for
+experimental and development purposes.
+      </para>
+
+      <para>
+Symbols exported by the loader (on behalf of the core X server) to
+modules are determined at compile time.  Only those symbols explicitly
+exported are available to modules.  All external symbols of loaded
+modules are exported to other modules, and to the core X server.  The
+loader can be requested to check for unresolved symbols at any time,
+and the action to be taken for unresolved symbols can be controlled by
+the caller of the loader.  Typically the caller identifies which symbols
+can safely remain unresolved and which cannot.
+      </para>
+
+      <para>
+NOTE:  Now that ISO-C allows pointers to functions and pointers to data to
+have different internal representations, some of the following interfaces
+will need to be revisited.

+    The vgahw module abstracts access to the standard VGA registers by

+    the <structname>vgaHWRec</structname> is created these function pointers are
+    initialised with the set of standard VGA I/O register access functions.
+    In addition to these, the vgahw module includes a basic set of MMIO

+    pointers can be initialised to these by calling the
+    <function>vgaHWSetMmioFuncs()</function> function described above.  Some

+The following is an outline for writing a basic unaccelerated driver

+most drivers (even those which don't fit that basic description).
+    </para>

+    <para>
+The information here is based on the initial conversion of the Matrox
+Millennium driver to the <quote>new design</quote>.  For a fleshing out and sample

+Note that this is an example only.  The approach used here will not be

+

+Each driver must reserve a unique driver name, and a string that is used
+to prefix all of its externally visible symbols.  This is to avoid name
+space clashes when loading multiple drivers.  The examples here are for

+.SH NAME
+exa \- new 2D acceleration architecture for X.Org
+.SH DESCRIPTION
+.B EXA
+provides a simple API for video drivers to implement for 2D acceleration.  It
+is a module loaded by drivers, and is not intended to be loaded on its own.
+See your driver's manual page for how to enable
+.BR EXA .
+.PP
+The
+.B EXA
+architecture is designed to make accelerating the Render extension simple and
+efficient, and results in various performance tradeoffs compared to XAA.  Some
+__xconfigfile__ options are available for debugging performance issues or
+driver rendering problems.  They are not intended for general use.
+.TP
+.BI "Option \*qEXANoComposite\*q \*q" boolean \*q
+Disables acceleration of the Composite operation, which is at the heart of
+the Render extension.  Not related to the Composite extension.  Default: No.
+.TP
+.BI "Option \*qEXANoUploadToScreen\*q \*q" boolean \*q
+Disables acceleration of uploading pixmap data to the framebuffer. Default: No.
+.TP
+.BI "Option \*qEXANoDownloadFromScreen\*q \*q" boolean \*q
+Disables acceleration of downloading of pixmap data from the framebuffer.
+.B NOTE:
+Not usable with drivers which rely on DownloadFromScreen succeeding.
+Default: No.
+.TP
+.BI "Option \*qMigrationHeuristic\*q \*q" anystr \*q
+Chooses an alternate pixmap migration heuristic, for debugging purposes.  The
+default is intended to be the best performing one for general use, though others
+may help with specific use cases.  Available options include \*qalways\*q,
+\*qgreedy\*q, and \*qsmart\*q.  Default: always.

+This is a submodule to access linux framebuffer devices.
+It is supported to work as helper module (like vgahw)
+for the chipset drivers.  There are functions for
+saving/restoring/setting video modes, set palette entries,
+and a few more helper functions.  Some of them can be
+hooked directly into ScrnInfoRec.
+
+In ../drivers/fbdev is a "chipset" driver.  It is a simple,
+non-accelerated and hardware-independent driver which works
+on top of this fbdevhw submodule.

+
+                 INT10  X86 Real Mode executor
+                 =============================
+
+		         PRELIMINARY
+
+INT10 is  a XFree86  module for soft-booting  and executing  real mode
+int10 BIOS calls. The BIOS call code is largely untested, yet.
+
+1. Usage
+========
+
+To   use   the   int10   module   in  a   driver   the   header   file
+xfree86/os-support/int10/xf86int10.h must be included.
+
+ a. Initialization
+ -----------------
+
+The int10-executer gets initialized by calling:
+
+   xf86Int10InfoPtr xf86InitInt10(int entityIndex);
+
+The  function  will soft-boot  any  non-primary  device  and return  a
+pointer  to a  xf86Int10InfoRec on  success. If  anything fails  or if
+int10 execution  is disabled by an  option in the  device section NULL
+will  be returned.   The driver  should store  this pointer  for later
+calls to other int10 module functions.
+
+ b. Memory allocation
+ --------------------
+
+To allocate memory in the real mode execution environment
+    
+   void * xf86Int10AllocPages(xf86Int10InfoPtr pInt,int num, int *off);
+
+can  be called.  It  allocates num  consecutive  pagesize chunks.   It
+returns the address of the allocated area. off is set to its offset in
+the real mode memory space.
+
+  void xf86Int10FreePages(xf86Int10InfoPtr pInt, void *pbase, int num);
+
+Is used to free num pages beginning at pbase.
+
+ c. Doing int10 BIOS calls
+ -------------------------
+
+The BIOS call is executed by calling:
+   
+   void xf86ExecX86int10(xf86Int10InfoPtr pInt);
+
+The number  of the interrupt (normally  10) and the  initial values of
+the ax, bx, cx, dx, si, di  and es x86-CPU registers can be set in the
+xf86Int10InfoRec  passed to  the function.   On return  this structure
+contains the  exit values  of the registers  listed above and  the CPU
+flag register.
+
+ d. De-initializing
+ -----------------
+
+If no further int10 calls are required for a certain chipset
+the driver should call:
+
+  void xf86FreeInt10(xf86Int10InfoPtr pInt);
+
+to free the memory allocated for real mode int10 calls.
+
+
+2. Porting issues
+=================
+
+The int10 real mode executor is  designed to run on top of various x86
+CPU emulators as well as in vm86  mode of a real x86 CPU. If used with
+a CPU  emulator the emulator and  CPU specific interfaces  can be held
+separate thus  requiring minimal efforts  to port the int10  module to
+new  platforms.   Currently  an  interface  to the  x86emu  real  mode
+emulator is  provided.  Since  details of setting  up and  running the
+vm86  mode   is  platform   dependent  both  the   platform  dependent
+environment and the emulation layer  have to be ported. Several helper
+functions are provided for that.
+
+A CPU emulator should meet certain requirements to be usable
+for the INT10 executor:
+
+1. It must trap  calls to intXX instructions and  pass execution to an
+   external  function  which  is   allowed  to  modify  CPU  registers
+   including  the instruction  pointer  (IP) before  returning to  the
+   emulator for  continuing execution.  When the external  function is
+   called the  IP must point to  the instruction past  the intXX call.
+
+2. The  emulator should  use externally  provided functions  to handle
+   PIO.
+
+3.  The emulator  should be able to use  externally provided functions
+ to access memory  from the real mode memory  environment.  Note, that
+ the  vm86  mode  usually  requires  one hunk  of  consecutive  memory
+ starting at address  0 in the process virtual  memory space.  Thus if
+ this mode is to be used, the OS environment has to be able to provide
+ that, ie. it must be able to remap the processes virtual memory space
+ onto itself.  If the  emulator is able  to handle memory  access thru
+ externally  provided functions the  real mode  process memory  can be
+ located anywhere  in the processes  virtual memory. It does  not even
+ have to be consecutive.
+
+4. The executor should terminate on encountering a 'hlt' instruction.
+
+
+Functions to implement:
+
+To simplify development  the code has been split  into a general setup
+part and an emulator specific one. A generic setup code is provided in
+generic.c.  It  should be  usable  with  any  emulator satisfying  the
+conditions mentioned  above. Therefore the following  section on int10
+setup may be skipped when porting int10 to new emulator.
+
+If the  vm86() is to be used  no memory access functions  can be used.
+Therefore the layout of the real mode memory image has to meet certain
+requirements. Therefore  when porting to  other platforms a  new setup
+code may  have to  be designed, too.  The following section  will give
+guidelines how  this may be  done. A sample implementation  using SysV
+IPC to  map the  appropriate real  mode memory image  to address  0 in
+virtual  address  space  just  prior  to execution  may  be  found  in
+xfree86/os-support/linux/int10/linux.c.
+
+On  non-PC like  platforms emulation  of certain  PC features  such as
+initialization of  BIOS int vectors, sys_BIOS constants  or PCI config
+method 1 can be turned on by defining _PC.
+
+I. Setup Code
+-------------
+
+This sets  up the real mode  memory image, calls the  emulator to POST
+the chipset if required and  maintains memory allocations in real mode
+address space.
+
+1. xf86Int10InfoPtr xf86InitInt10(int entityIndex);
+
+This  function should  first find  the screen  assigned to  the entity
+carrying entitiyIndex and then call
+
+       Bool int10skip(ScrnInfoPtr pScrn)
+
+to find out if the user  has requested not to initialize int10.  If so
+xf86InitInt10()  should  return  NULL. Otherwise  an  xf86Int10InfoRec
+should be allocated.  This structure contains the following fields:
+
+    a. int entityIndex   - index of the entity whose BIOS is to be 
+                           executed.
+    b. int scrnIndex     - index of the screen assigned the entity.
+    c. pointer cpuRegs   - pointer to a emulator/vm86-mode private 
+                           structure.  May hold cpu register values 
+                           for the emulator.
+    d. CARD16 BIOSseg    - Video BIOS segment address.
+    e. pointer private   - pointer to a os specific data structure.
+    f. struct _int10Mem* - pointer to a structure to hold the memory
+                           access functions for use by an emulator.
+    g. int num           - number of the int to be called.
+    h. int ax..es,flags  - CPU register values to pass to int-call.
+
+The Init  function should initialize  a-f. To initialize  the emulator
+specific execute environment the function
+
+     Bool xf86Int10ExecSetup(xf86Int10InfoPtr pInt)
+
+should be called. If this function returns FALSE any already allocated
+memory should be freed and xf86Int10Init(0 should exit returning NULL.
+
+If the  platform has  a PC  like system BIOS  it may  be copied  to or
+mapped into memory  locations SYS_BIOS to SYS_SIZE-1 of  the real mode
+memory environment of this process. Otherwise the helper function: 
+
+int setup_system_bios(CARD32 base_addr); 
+
+may be  called to set  up a rudimentary  system BIOS sufficient  to be
+used to  boot video BIOSes.   base_addr specifies the  virtual address
+corresponding to SYS_BIOS in the  real mode environment.  If a PC-like
+int vector and BIOS data area is available it should be copied to 0 to
+LOW_PAGE_SIZE of the entities real mode environment.  In this case the
+video interrupt  related entries should  be reset for  all non-primary
+cards by calling:
+
+void reset_int_vect(xf86Int10InfoPtr pInt); To initialize the
+
+correct video BIOS  entry points the BIOS must  be warm-booted.  If no
+PC-like int vector is available one can be set up by calling 
+
+void setup_int_vect(xf86Int10InfoPtr pInt); 
+
+In this  case the  video BIOS  has to be  warm-booted always.   If the
+video BIOS  for this entity has  been installed during boot  it may be
+mapped (or  copied) directly to the  correct address in  the real mode
+memory environment.  Otherwise
+
+int mapPciRom(xf86Int10InfoPtr pInt, unsigned char * address); 
+
+should  be called  to copy  the BIOS  image from  PCI  ROM.  'address'
+specifies the address this image should be copied to. Sufficient space
+to  hold an entire  BIOS image  should be  allocated prior  to calling
+mapPciRom(). This function  will return the size of  the BIOS image in
+bytes  if  it   was  able  to  successfully  copy   the  image  and  0
+otherwise. To create a well defined point to exit the softbooter
+
+void set_return_trap(xf86Int10Ptr pInt); 
+
+may be called.  It sets up a 'hlt' instruction  in the emulator memory
+just above the BIOS variable area. Before entering real mode execution
+this address will be pushed onto  the return stack.  If the BIOS needs
+to be  warm-booted this should be done  before leaving xf86InitInt10()
+by setting num in the xf86Int10InfoRec to 0xe6 and calling
+
+void xf86ExecX86int10(xf86Int10IfoPtr pInt); 
+
+The  implementation of this  function will  be discussed  below.  This
+function  should be  wrapped  by calls  to void  LockLegacyVGA(screen,
+legacyVGAPtr vga); and void UnlockLegacyVGA(screen, legacyVGAPtr vga);
+The struct  vga is  used to hold  the state  of the legacy  VGA access
+registers  if  a legacy  VGA  device  exists.  xf86InitInt10()  should
+return a pointer to the xf86Int10InfoRec allocated.
+
+2. Bool MapCurrentInt10(xf86Int10InfoPtr pInt);
+
+In case  a platform specific  mapping has to  be performed to  map the
+memory allocated for the real  mode memory environment into a specific
+location prior to executing the x86 real mode code a function
+
+        Bool MapCurrentInt10(xf86Int10InfoPtr pInt);
+
+has to  be provided. It will  be called by a  helper function whenever
+the active entity changes. If the  vm86 mode is used it is most likely
+that the 1MB real mode memory space located somewhere in the processes
+virtual memory  will have to be  remapped to address 0  of the virtual
+memory space.
+
+3.   void xf86FreeInt10(xf86Int10InfoPtr pInt);
+
+To free all memory allocated for video BIOS calls of a specific entity
+the function
+
+       void xf86FreeInt10(xf86Int10InfoPtr pInt);
+
+should  be  provided.  If  the  entity  to  be  freed  was  mapped  by
+MapCurrentInt10() this mapping needs to be undone also.
+
+4. 
+   void * xf86Int10AllocPages(xf86Int10InfoPtr pInt,int num, int *off)
+   void xf86Int10FreePages(xf86Int10InfoPtr pInt, void *pbase, int num)
+
+xf86Int10AllocPages()  should  allocate  'num'  consecutive  page-size
+chunks of memory. In real mode memory space this range needs to occupy
+consecutive addresses,  too. The function  must return the  address of
+this memory.  The offset in real  mode memory needs to  be returned in
+'off'. If  no block of 'num'  pages are available  the function should
+return NULL.
+
+xf86Int10FreePages() will  free the  'num' pages starting  at 'pbase'.
+'num'  is  equal  to  the  number  of  pages  allocated  by  a  single
+xf86Int10AllocatePages()  call. 'pbase'  is the  address of  the range
+previously returned by xf86Int10AllocatePages().
+
+II. Emulator specific functions
+-------------------------------
+
+1. Bool xf86Int10ExecSetup(xf86Int10InfoPtr pInt);
+
+This function will  be called from xf86InitInt10(). It  may be used to
+set  up   the  static  emulator   specific  part  of  the   real  mode
+environment. On success it should return TRUE.
+
+2. xf86ExecX86int10(xf86Int10InfoPtr pInt);
+
+This function  gets called  to execute  an int call.  It may  call the
+helper function:
+
+       void setup_int(xf86Int10InfoPrt pInt);
+
+to copy the register values  to the emulator specific locations and to
+set up the non-static real mode execution environment.  On return from
+setup_int()   'Int10Current'   holds   a   pointer  to   the   current
+xf86Int10InfoRec.
+
+It should start execution by calling 
+
+       Bool int_handler(xf86Int10InfoPtr pInt);
+
+and if this function returns TRUE it should call whatever necessary to
+continue execution until a  'hlt' instruction is encountered.  To copy
+the resulting register values back to the xf86Int10InfoRec structure
+
+     void finish_int(xf86Int10InfoPtr pInt);
+
+should be called. 
+
+Helper  functions are  provided to  aid the  implementation of  a vm86
+call:
+
+  Bool vm86_GP_fault(xf86Int10InfoPtr pInt);
+
+This  function  handles  instructions  which  cause  a  vm86  call  to
+trap.  PIO  access  is handled  by  the  in/out  calls as  defined  in
+compiler.h. Optionally the PIO  instructions can be logged by defining
+PRINT_PORT in xf86int10.h. This is meant for debugging purposes.
+
+Unknown  instructions  and   'hlt'  cause  vm86_GP_fault()  to  return
+FALSE. Otherwise TRUE is returned.
+
+Note: This  function is  currently based on  the Linux vm86  call.  It
+might have  to be modified  or even rewritten  for other OS.   So your
+milage may vary.
+
+Functions to dump memory, code, xf86 CPU register values and stack are
+also provided.  Take a  look at  helper.c To view  a memory  range the
+function
+
+    void dprint(unsigned long start, unsigned long size)
+
+is provided. The use should be self explanatory.
+
+Register  and memory  access functions  are provided  in helper_mem.c.
+The PIO register access functions  can trap access to PCI config space
+access register (config method 1) if _PC is not defined.
+
+A header  file 'defines.h' is required to  define OS/emulator specific
+ways  to access  memory and  xf86 CPU  registers: Defines  need  to be
+provided     for    memory     byte/work/long     read/write    access
+(MEM_RB(name,addr),MEM_RW(name,addr),MEM_RL(name,addr),
+MEM_WB(name,addr,val),MEM_WL(name,addr,val),MEM_WL(name,addr,val))   of
+the real mode memory environment. 'name' will contain a pointer to the
+current   xf86Int10InfoRec.  Currently   defines  are   available  for
+vm86-mode under  Linux and x86emu.  They may be activated  by defining
+_X86EMU or _VM86_LINUX respectively.
+
+Note: Emulators usually are not able to pass this pointer when calling
+memory  access functions.  In this  case a  global variable  should be
+defined  which can  hold this  pointer. This  variable can  be  set in
+MapCurrentInt10().  It also  must be  set in  xf86InitInt10()  if this
+function  calls the  memory  access functions  either  directly or  by
+calling  xf86ExecX86int10(pInt).   Defines   to  access  the  emulator
+specific   xf86   CPU    register   locations   are   also   required:
+X86_EAX,...,X86_EFLAGS  for  access  of  the full  32  bit  registers,
+X86_AX...X86_FLAGS   for  access   of   the  16   bit  registers   and
+XF86_AL,XF86_BL,XF86_CL,XF86_DL  to  access  the  lower  byte  of  the
+AX,BX,CX and DX register.

+ * This scheme requires that the kernel allow mmap()'ing of a host bridge's I/O
+ * and memory spaces through its /proc/bus/pci/BUS/DFN entry.  Which one is
+ * determined by a prior ioctl().
+ *
+ * For the sparc64 port, this means 2.4.12 or later.  For ppc, this
+ * functionality is almost, but not quite there yet.  Alpha and other kernel
+ * ports to multi-domain architectures still need to implement this.
+ *
+ * This scheme is also predicated on the use of an IOADDRESS compatible type to
+ * designate I/O addresses.  Although IOADDRESS is defined as an unsigned
+ * integral type, it is actually the virtual address of, i.e. a pointer to, the
+ * I/O port to access.  And so, the inX/outX macros in "compiler.h" need to be
+ * #define'd appropriately (as is done on SPARC's).
+ *
+ * Another requirement to port this scheme to another multi-domain architecture
+ * is to add the appropriate entries in the pciControllerSizes array below.
+ *
+ * TO DO:  Address the deleterious reaction some host bridges have to master
+ *         aborts.  This is already done for secondary PCI buses, but not yet
+ *         for accesses to primary buses (except for the SPARC port, where
+ *         master aborts are avoided during PCI scans).

+XFramebuffer aperture driver.
+X
+XThis driver was written to provide a device that, unlike /dev/mem, allows
+Xmmap()'ing of ranges beyond installed memory.
+X
+XThe original x86-based version of this driver was the collaborative work of
+XDoug Anson (danson@lgc.com), and David Holland (davidh@use.com).  It has since
+Xbeen rewritten to also work on sparc machines and - later on - also on sparcv9 
+Xand recently amd64 64 bit kernels.
+XIt flawlessly compiles and installs on Solaris 10 and 11 now.
+X
+X
+XInstallation instructions:
+X
+X1) Check the Makefile, for appropriate CC, and CFLAGS definitions.  Compiling
+X   with APERTURE_DEBUG defined means the driver will generate reams of
+X   debugging output.  You'll probably want to leave this off...
+X
+X2) Type 'make' (or 'gmake').  Both the driver and test program should compile 
+X   without any problems. No warning messages should be generated.
+X
+X3) Become 'root'.
+X
+X4) Type 'make install' and 'make add_drv'.  The screen should look something
+X   like this:
+X
+X	# make install
+X	cp aperture aperture.conf /kernel/drv
+X	# make add_drv
+X	add_drv aperture
+X
+X   On a sparcv9 machine this will mention the /kernel/drv/sparcv9 directory
+X   instead of /kernel/drv. Similarily /kernel/drv/amd64 should be used on amd64.
+X
+X   This installs the driver to the system.
+X
+X5) While as root modify the file /etc/devlink.tab, adding these lines:
+X
+X# The following entry is for the framebuffer driver
+Xtype=ddi_pseudo;name=aperture	fbs/\M0
+X
+X   Add that line exactly as shown. You may also simply add the
+X   contents of the devlink.tab file supplied to /etc/devlink.tab.
+X   It contains the lines as well.  (Yes, that is a tab between
+X   aperture and fbs, not spaces - very important)
+X
+X6) Perform a reconfiguration boot of the system.
+X
+X	# touch /reconfigure
+X	# init 6
+X
+XBug reports, questions, suggestions, etc can be sent to xfree86@xfree86.org.

+			CURSOR.NOTES
+
+  This file describes how to add hardware cursor support to a chipset
+driver.  Though the cursor support itself is in the ramdac module,
+cursor management is separate from the rest of the module.
+
+
+1) CURSOR INITIALIZATION AND SHUTDOWN
+
+   All relevant prototypes and defines are in xf86Cursor.h.
+
+  To initialize the cursor, the driver should allocate an 
+xf86CursorInfoRec via xf86CreateCursorInfoRec(), fill it out as described 
+later in this  document and pass it to xf86InitCursor().  xf86InitCursor() 
+must be called _after_ the software cursor initialization (usually
+miDCInitialize).
+
+   When shutting down, the driver should free the xf86CursorInfoRec
+structure in its CloseScreen function via xf86DestroyCursorInfoRec().
+
+
+2) FILLING OUT THE xf86CursorInfoRec
+
+   The driver informs the ramdac module of it's hardware cursor capablities by
+filling out an xf86CursorInfoRec structure and passing it to xf86InitCursor().
+The xf86CursorInfoRec contains the following function pointers:
+
+
+/**** These functions are required ****/
+
+void ShowCursor(ScrnInfoPtr pScrn)
+
+    ShowCursor should display the current cursor.
+
+void HideCursor(ScrnInfoPtr pScrn)
+
+    HideCursor should hide the current cursor.
+
+void SetCursorPosition(ScrnInfoPtr pScrn, int x, int y)
+
+    Set the cursor position to (x,y).  X and/or y may be negative
+    indicating that the cursor image is partially offscreen on
+    the left and/or top edges of the screen.  It is up to the
+    driver to trap for this and deal with that situation.
+
+void SetCursorColors(ScrnInfoPtr pScrn, int bg, int fg)
+
+    Set the cursor foreground and background colors.  In 8bpp, fg and
+    bg are indicies into the current colormap unless the 
+    HARDWARE_CURSOR_TRUECOLOR_AT_8BPP flag is set.  In that case
+    and in all other bpps the fg and bg are in 8-8-8 RGB format.
+    
+void LoadCursorImage(ScrnInfoPtr pScrn, unsigned char *bits)
+
+    LoadCursorImage is how the hardware cursor bits computed by the
+    RealizeCursor function will be passed to the driver when the cursor
+    shape needs to be changed.
+
+
+/**** These functions are optional ****/
+
+    
+unsigned char* RealizeCursor(xf86CursorInfoPtr infoPtr, CursorPtr pCurs) 
+
+    If RealizeCursor is not provided by the driver, one will be provided
+    for you based on the Flags field described below.  The driver must
+    provide this function if the hardware cursor format is not one of
+    the common ones supported by this module.
+  
+
+Bool UseHWCursor(ScreenPtr pScreen, CursorPtr pCurs)
+
+    If the driver is unable to use a hardware cursor for reasons
+    other than the cursor being larger than the maximum specified
+    in the MaxWidth or MaxHeight field below, it can supply the
+    UseHWCursor function.  If UseHWCursor is provided by the driver,
+    it will be called whenever the cursor shape changes or the video
+    mode changes.  This is useful for when the hardware cursor cannot
+    be used in interlaced or doublescan modes.
+
+
+/**** The following fields are required ****/
+
+MaxWidth
+MaxHeight
+
+    These indicate the largest sized cursor that can be a hardware
+    cursor.  It will fall back to a software cursor when a cursor
+    exceeding this size needs to be used.
+
+
+Flags
+
+   /* Color related flags */
+
+   HARDWARE_CURSOR_TRUECOLOR_AT_8BPP
+
+   This indicates that the colors passed to the SetCursorColors
+   function should not be in 8-8-8 RGB format in 8bpp but rather,
+   they should be the pixel values from the current colormap.
+
+
+   /* Cursor data loading flags */
+
+   HARDWARE_CURSOR_SHOW_TRANSPARENT
+
+   The HideCursor entry will normally be called instead of displaying a
+   completely transparent cursor, or when a switch to a software cursor
+   needs to occur.  This flag prevents this behaviour, thus causing the
+   LoadCursorImage entry to be called with transparent cursor data.
+   NOTE:  If you use this flag and provide your own RealizeCursor() entry,
+          ensure this entry returns transparent cursor data when called
+          with a NULL pCurs parameter.
+
+   HARDWARE_CURSOR_UPDATE_UNHIDDEN
+
+   This flag prevents the HideCursor call that would normally occur just before
+   the LoadCursorImage entry is to be called to load a new hardware cursor
+   image.
+
+
+   /* Cursor data packing flags */
+
+   Hardware cursor data consists of two pieces, a source and a mask.
+   The mask is a bitmap indicating which parts of the cursor are 
+   transparent and which parts are drawn.  The source is a bitmap
+   indicating which parts of the non-transparent portion of the the
+   cursor should be painted in the foreground color and which should
+   be painted in the background color.
+
+   HARDWARE_CURSOR_INVERT_MASK
+
+   By default, set bits indicate the opaque part of the mask bitmap
+   and clear bits indicate the transparent part.  If your hardware
+   wants this the opposite way, this flag will invert the mask.
+
+   HARDWARE_CURSOR_SWAP_SOURCE_AND_MASK
+
+   By default, RealizeCursor will store the source first and then
+   the mask.  If the hardware needs this order reversed then this
+   flag should be set.
+
+   HARDWARE_CURSOR_AND_SOURCE_WITH_MASK
+
+   This flag will have the module logical AND the source with the mask to make  
+   sure there are no source bits set if the corresponding mask bits 
+   aren't set.  Some hardware will not care if source bits are set where
+   there are supposed to be transparent areas, but some hardware will
+   interpret this as a third cursor color or similar.  That type of
+   hardware will need this flag set.
+
+   HARDWARE_CURSOR_BIT_ORDER_MSBFIRST
+
+   By default, it is assumed that the least significant bit in each byte
+   corresponds to the leftmost pixel on the screen.  If your hardware
+   has this reversed you should set this flag.
+
+   HARDWARE_CURSOR_NIBBLE_SWAPPED
+
+   If your hardware requires byte swapping of the hardware cursor, enable
+   this option.
+
+
+   /* Source-Mask interleaving flags */
+
+   By default the source and mask data are inlined (source first unless
+   the HARDWARE_CURSOR_SWAP_SOURCE_AND_MASK flag is set).  Some hardware
+   will require the source and mask to be interleaved, that is, X number
+   of source bits should packed and then X number of mask bits repeating
+   until the entire pattern is stored.  The following flags describe the
+   bit interleave.
+
+   HARDWARE_CURSOR_SOURCE_MASK_NOT_INTERLEAVED   
+
+   This one is the default.
+ 
+   The following are for interleaved cursors.
+    
+   HARDWARE_CURSOR_SOURCE_MASK_INTERLEAVE_1        
+   HARDWARE_CURSOR_SOURCE_MASK_INTERLEAVE_8        
+   HARDWARE_CURSOR_SOURCE_MASK_INTERLEAVE_16       
+   HARDWARE_CURSOR_SOURCE_MASK_INTERLEAVE_32       
+   HARDWARE_CURSOR_SOURCE_MASK_INTERLEAVE_64   
+
+   And once again, if your hardware requires something different than
+   these packing styles, your driver can supply its own RealizeCursor
+   function.

+ *
+ * The GTF EXCEL(TM) SPREADSHEET, a sample (and the definitive)
+ * implementation of the GTF Timing Standard, is available at:
+ *
+ * ftp://ftp.vesa.org/pub/GTF/GTF_V1R1.xls
+ *
+ *
+ *
+ * This program takes a desired resolution and vertical refresh rate,
+ * and computes mode timings according to the GTF Timing Standard.
+ * These mode timings can then be formatted as an XServer modeline
+ * or a mode description for use by fbset(8).
+ *
+ *
+ *
+ * NOTES:
+ *
+ * The GTF allows for computation of "margins" (the visible border
+ * surrounding the addressable video); on most non-overscan type
+ * systems, the margin period is zero.  I've implemented the margin
+ * computations but not enabled it because 1) I don't really have
+ * any experience with this, and 2) neither XServer modelines nor
+ * fbset fb.modes provide an obvious way for margin timings to be
+ * included in their mode descriptions (needs more investigation).
+ * 
+ * The GTF provides for computation of interlaced mode timings;
+ * I've implemented the computations but not enabled them, yet.
+ * I should probably enable and test this at some point.
+ *
+ * 
+ *
+ * TODO:
+ *
+ * o Add support for interlaced modes.
+ *
+ * o Implement the other portions of the GTF: compute mode timings
+ *   given either the desired pixel clock or the desired horizontal
+ *   frequency.
+ *
+ * o It would be nice if this were more general purpose to do things
+ *   outside the scope of the GTF: like generate double scan mode
+ *   timings, for example.
+ *   
+ * o Printing digits to the right of the decimal point when the
+ *   digits are 0 annoys me.
+ *
+ * o Error checking.

+.SH NAME
+cvt - calculate VESA CVT mode lines
+.SH SYNOPSIS
+.B cvt
+.RB [ \-v | \-\-verbose ]
+.RB [ \-r | \-\-reduced ]
+.I h-resolution
+.I v-resolution
+.RB [ refresh ]
+.SH DESCRIPTION
+.I Cvt
+is a utility for calculating VESA Coordinated Video Timing modes.  Given the
+desired horizontal and vertical resolutions, a modeline adhering to the CVT
+standard is printed. This modeline can be included in __xservername__
+.B __xconfigfile__(__filemansuffix__)
+.
+
+.SH OPTIONS
+.TP 8
+.BR refresh
+Provide a vertical refresh rate in kHz.  The CVT standard prefers either 50.0,
+60.0, 75.0 or 85.0kHz.  The default is 60.0kHz.
+.TP 8
+.BR \-v | \-\-verbose
+Warn verbosely when a given mode does not completely correspond with CVT
+standards.
+.TP 8
+.BR \-r | \-\-reduced
+Create a mode with reduced blanking.  This allows for higher frequency signals,
+with a lower or equal dotclock. Not for Cathode Ray Tube based displays though.

+.SH DESCRIPTION
+.I Gtf
+is a utility for calculating VESA GTF modes.  Given the desired
+horizontal and vertical resolutions and refresh rate (in Hz), the parameters
+for a matching VESA GTF mode are printed out.  Two output formats are
+supported: mode lines suitable for the __xservername__
+.B __xconfigfile__(__filemansuffix__)
+file, and mode parameters suitable for the Linux
+.B fbset(8)
+utility.
+
+.SH OPTIONS
+.TP 8
+.BR \-v | \-\-verbose
+Enable verbose printouts  This shows a trace for each step of the
+computation.
+.TP 8
+.BR \-x | \-\-xorgmode
+Print the mode parameters as __xservername__-style mode lines.  This is the
+default format.
+.TP 8
+.BR \-f | \-\-fbset
+Print the mode parameters in a format suitable for
+.BR fbset(8) .
+.SH "SEE ALSO"

+This program is based on the Generalized Timing Formula (GTF(TM)) Standard
+Version: 1.0, Revision: 1.0.  The GTF Excel(TM) spreadsheet, a sample
+(and the definitive) implementation of the GTF Timing Standard is
+available at <ftp://ftp.vesa.org/pub/GTF/VTF_V1R1.xls>.

+     * OK, so much for theory.  Now, let's deal with the >real< world...
+     *
+     * The above CRTC settings are precise in theory, except that many, if not
+     * most, VGA clones fail to reset the blanking signal when the character or
+     * line counter reaches [HV]Total.  In this case, the signal is only
+     * unblanked when the counter reaches [HV]BlankEnd (mod 64, 128 or 256 as
+     * the case may be) at the start of the >next< scanline or frame, which
+     * means only part of the screen shows.  This affects how null overscans
+     * are to be implemented on such adapters.
+     *
+     * Henceforth, VGA cores that implement this broken, but unfortunately
+     * common, behaviour are to be designated as KGA's, in honour of Koen
+     * Gadeyne, whose zeal to eliminate overscans (read: fury) set in motion
+     * a series of events that led to the discovery of this problem.
+     *
+     * Some VGA's are KGA's only in the horizontal, or only in the vertical,
+     * some in both, others in neither.  Don't let anyone tell you there is
+     * such a thing as a VGA "standard"...  And, thank the Creator for the fact
+     * that Hilbert spaces are not yet implemented in this industry.
+     *
+     * The following implements a trick suggested by David Dawes.  This sets
+     * [HV]BlankEnd to zero if the blanking interval does not already contain a
+     * 0-point, and decrements it by one otherwise.  In the latter case, this
+     * will produce a left and/or top overscan which the colourmap code will
+     * (still) need to ensure is as close to black as possible.  This will make
+     * the behaviour consistent across all chipsets, while allowing all
+     * chipsets to display the entire screen.  Non-KGA drivers can ignore the
+     * following in their own copy of this code.

+whether the access is relative to DS or SS.  That is the function of the
+cpu-state-varible M.x86.mode. There are several potential states:
+

+
+	cs segment override
+	ds segment override
+	es segment override
+	fs segment override

+*
+* Language:		ANSI C
+* Environment:	Any
+* Developer:    Kendall Bennett
+*
+* Description:  This file includes subroutines to implement the decoding
+*               and emulation of all the x86 processor instructions.
+*
+* There are approximately 250 subroutines in here, which correspond
+* to the 256 byte-"opcodes" found on the 8086.  The table which
+* dispatches this is found in the files optab.[ch].
+*
+* Each opcode proc has a comment preceeding it which gives it's table
+* address.  Several opcodes are missing (undefined) in the table.
+*
+* Each proc includes information for decoding (DECODE_PRINTF and
+* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc
+* functions (START_OF_INSTR, END_OF_INSTR).
+*
+* Many of the procedures are *VERY* similar in coding.  This has
+* allowed for a very large amount of code to be generated in a fairly
+* short amount of time (i.e. cut, paste, and modify).  The result is
+* that much of the code below could have been folded into subroutines
+* for a large reduction in size of this file.  The downside would be
+* that there would be a penalty in execution speed.  The file could
+* also have been *MUCH* larger by inlining certain functions which
+* were called.  This could have resulted even faster execution.  The
+* prime directive I used to decide whether to inline the code or to
+* modularize it, was basically: 1) no unnecessary subroutine calls,
+* 2) no routines more than about 200 lines in size, and 3) modularize
+* any code that I might not get right the first time.  The fetch_*
+* subroutines fall into the latter category.  The The decode_* fall
+* into the second category.  The coding of the "switch(mod){ .... }"
+* in many of the subroutines below falls into the first category.
+* Especially, the coding of {add,and,or,sub,...}_{byte,word}
+* subroutines are an especially glaring case of the third guideline.
+* Since so much of the code is cloned from other modules (compare
+* opcode #00 to opcode #01), making the basic operations subroutine
+* calls is especially important; otherwise mistakes in coding an
+* "add" would represent a nightmare in maintenance.

+*
+* Description:  This file contains the code to implement the primitive
+*				machine operations used by the emulation code in ops.c
+*
+* Carry Chain Calculation
+*
+* This represents a somewhat expensive calculation which is
+* apparently required to emulate the setting of the OF and AF flag.
+* The latter is not so important, but the former is.  The overflow
+* flag is the XOR of the top two bits of the carry chain for an
+* addition (similar for subtraction).  Since we do not want to
+* simulate the addition in a bitwise manner, we try to calculate the
+* carry chain given the two operands and the result.
+*
+* So, given the following table, which represents the addition of two
+* bits, we can derive a formula for the carry chain.
+*
+* a   b   cin   r     cout
+* 0   0   0     0     0
+* 0   0   1     1     0
+* 0   1   0     1     0
+* 0   1   1     0     1
+* 1   0   0     1     0
+* 1   0   1     0     1
+* 1   1   0     0     1
+* 1   1   1     1     1
+*
+* Construction of table for cout:
+*
+* ab
+* r  \  00   01   11  10
+* |------------------
+* 0  |   0    1    1   1
+* 1  |   0    0    1   0
+*
+* By inspection, one gets:  cc = ab +  r'(a + b)
+*
+* That represents alot of operations, but NO CHOICE....
+*
+* Borrow Chain Calculation.
+*
+* The following table represents the subtraction of two bits, from
+* which we can derive a formula for the borrow chain.
+*
+* a   b   bin   r     bout
+* 0   0   0     0     0
+* 0   0   1     1     1
+* 0   1   0     1     1
+* 0   1   1     0     1
+* 1   0   0     1     0
+* 1   0   1     0     0
+* 1   1   0     0     0
+* 1   1   1     1     1
+*
+* Construction of table for cout:
+*
+* ab
+* r  \  00   01   11  10
+* |------------------
+* 0  |   0    1    0   0
+* 1  |   1    1    1   0
+*
+* By inspection, one gets:  bc = a'b +  r(a' + b)

+* Description:  Program to validate the x86 emulator library for
+*               correctness. We run the emulator primitive operations
+*               functions against the real x86 CPU, and compare the result
+*               and flags to ensure correctness.
+*
+*               We use inline assembler to compile and build this program.

+/********************************************************************/
+
+0) WHAT IS XAA
+	
+   XAA (the XFree86 Acceleration Architecture) is a device dependent
+layer that encapsulates the unaccelerated framebuffer rendering layer,
+intercepting rendering commands sent to it from higher levels of the
+server.  For rendering tasks where hardware acceleration is not 
+possible, XAA allows the requests to proceed to the software rendering
+code.  Otherwise, XAA breaks the sometimes complicated X primitives
+into simpler primitives more suitable for hardware acceleration and
+will use accelerated functions exported by the chipset driver to 
+render these.
+
+   XAA provides a simple, easy to use driver interface that allows
+the driver to communicate its acceleration capabilities and restrictions
+back to XAA.  XAA will use the information provided by the driver
+to determine whether or not acceleration will be possible for a
+particular X primitive.
+
+
+
+1) XAA INITIALIZATION AND SHUTDOWN
+
+   All relevant prototypes and defines are in xaa.h.
+
+   To Initialize the XAA layer, the driver should allocate an XAAInfoRec
+via XAACreateInfoRec(), fill it out as described in this document
+and pass it to XAAInit().  XAAInit() must be called _after_ the 
+framebuffer initialization (usually cfb?ScreenInit or similar) since 
+it is "wrapping" that layer.  XAAInit() should be called _before_ the 
+cursor initialization (usually miDCInitialize) since the cursor
+layer needs to "wrap" all the rendering code including XAA.
+
+   When shutting down, the driver should free the XAAInfoRec
+structure in its CloseScreen function via XAADestroyInfoRec().
+The prototypes for the functions mentioned above are as follows:
+
+   XAAInfoRecPtr XAACreateInfoRec(void);
+   Bool XAAInit(ScreenPtr, XAAInfoRecPtr);
+   void XAADestroyInfoRec(XAAInfoRec);
+
+   The driver informs XAA of it's acceleration capablities by
+filling out an XAAInfoRec structure and passing it to XAAInit().
+The XAAInfoRec structure contains many fields, most of which are
+function pointers and flags.  Each primitive will typically have
+two functions and a set of flags associated with it, but it may
+have more.  These two functions are the "SetupFor" and "Subsequent" 
+functions.  The "SetupFor" function tells the driver that the 
+hardware should be initialized for a particular type of graphics 
+operation.  After the "SetupFor" function, one or more calls to the 
+"Subsequent" function will be made to indicate that an instance
+of the particular primitive should be rendered by the hardware.
+The details of each instance (width, height, etc...) are given
+with each "Subsequent" function.   The set of flags associated
+with each primitive lets the driver tell XAA what its hardware
+limitations are (eg. It doesn't support a planemask, it can only
+do one of the raster-ops, etc...).
+
+  Of the XAAInfoRec fields, one is required.  This is the
+Sync function.  XAA initialization will fail if this function
+is not provided.
+
+void Sync(ScrnInfoPtr pScrn)			/* Required */
+
+   Sync will be called when XAA needs to be certain that all
+   graphics coprocessor operations are finished, such as when
+   the framebuffer must be written to or read from directly
+   and it must be certain that the accelerator will not be
+   overwriting the area of interest.
+
+   One needs to make certain that the Sync function not only
+   waits for the accelerator fifo to empty, but that it waits for
+   the rendering of that last operation to complete.
+
+   It is guaranteed that no direct framebuffer access will
+   occur after a "SetupFor" or "Subsequent" function without
+   the Sync function being called first.
+
+
+
+2)  THE PRIMITIVES
+
+2.0  Generic Flags
+
+  Each primitive type has a set of flags associated with it which
+allow the driver to tell XAA what the hardware limitations are.
+The common ones are as follows:
+
+/* Foreground, Background, rop and planemask restrictions */
+
+   GXCOPY_ONLY
+
+     This indicates that the accelerator only supports GXcopy
+     for the particular primitive.
+
+   ROP_NEEDS_SOURCE
+
+     This indicates that the accelerator doesn't supports a
+     particular primitive with rops that don't involve the source.
+     These rops are GXclear, GXnoop, GXinvert and GXset. If neither
+     this flag nor GXCOPY_ONLY is defined, it is assumed that the
+     accelerator supports all 16 raster operations (rops) for that
+     primitive.
+
+   NO_PLANEMASK
+
+     This indicates that the accelerator does not support a hardware
+     write planemask for the particular primitive.
+
+   RGB_EQUAL
+
+     This indicates that the particular primitive requires the red, 
+     green and blue bytes of the foreground color (and background color,
+     if applicable) to be equal. This is useful for 24bpp when a graphics
+     coprocessor is used in 8bpp mode, which is not uncommon in older
+     hardware since some have no support for or only limited support for 
+     acceleration at 24bpp. This way, many operations will be accelerated 
+     for the common case of "grayscale" colors.  This flag should only
+     be used in 24bpp.
+
+  In addition to the common ones listed above which are possible for
+nearly all primitives, each primitive may have its own flags specific
+to that primitive.  If such flags exist they are documented in the
+descriptions of those primitives below.
+ 
+
+
+
+2.1  Screen to Screen Copies
+
+   The SetupFor and Subsequent ScreenToScreenCopy functions provide
+   an interface for copying rectangular areas from video memory to
+   video memory.  To accelerate this primitive the driver should
+   provide both the SetupFor and Subsequent functions and indicate
+   the hardware restrictions via the ScreenToScreenCopyFlags.  The
+   NO_PLANEMASK, GXCOPY_ONLY and ROP_NEEDS_SOURCE flags as described
+   in Section 2.0 are valid as well as the following:
+
+    NO_TRANSPARENCY
+     
+      This indicates that the accelerator does not support skipping
+      of color keyed pixels when copying from the source to the destination.
+
+    TRANSPARENCY_GXCOPY_ONLY
+
+      This indicates that the accelerator supports skipping of color keyed
+      pixels only when the rop is GXcopy.
+
+    ONLY_LEFT_TO_RIGHT_BITBLT
+
+      This indicates that the hardware only accepts blitting when the
+      x direction is positive.
+
+    ONLY_TWO_BITBLT_DIRECTIONS
+
+      This indicates that the hardware can only cope with blitting when
+      the direction of x is the same as the direction in y.
+
+
+void SetupForScreenToScreenCopy( ScrnInfoPtr pScrn,
+			int xdir, int ydir,
+			int rop,
+			unsigned int planemask,
+			int trans_color )
+
+    When this is called, SubsequentScreenToScreenCopy will be called
+    one or more times directly after.  If ydir is 1, then the accelerator
+    should copy starting from the top (minimum y) of the source and
+    proceed downward.  If ydir is -1, then the accelerator should copy
+    starting from the bottom of the source (maximum y) and proceed
+    upward.  If xdir is 1, then the accelerator should copy each
+    y scanline starting from the leftmost pixel of the source.  If
+    xdir is -1, it should start from the rightmost pixel.  
+       If trans_color is not -1 then trans_color indicates that the
+    accelerator should not copy pixels with the color trans_color
+    from the source to the destination, but should skip them. 
+    Trans_color is always -1 if the NO_TRANSPARENCY flag is set.
+ 
+
+void SubsequentScreenToScreenCopy(ScrnInfoPtr pScrn,
+			int x1, int y1,
+			int x2, int y2,
+			int width, int height)
+
+    Copy a rectangle "width" x "height" from the source (x1,y1) to the 
+    destination (x2,y2) using the parameters passed by the last
+    SetupForScreenToScreenCopy call. (x1,y1) and (x2,y2) always denote 
+    the upper left hand corners of the source and destination regardless 
+    of which xdir and ydir values are given by SetupForScreenToScreenCopy.  
+
+
+
+2.2 Solid Fills
+
+   The SetupFor and Subsequent SolidFill(Rect/Trap) functions provide
+   an interface for filling rectangular areas of the screen with a
+   foreground color.  To accelerate this primitive the driver should
+   provide both the SetupForSolidFill and SubsequentSolidFillRect 
+   functions and indicate the hardware restrictions via the SolidFillFlags.
+   The driver may optionally provide a SubsequentSolidFillTrap if
+   it is capable of rendering the primitive correctly.  
+   The GXCOPY_ONLY, ROP_NEEDS_SOURCE, NO_PLANEMASK and RGB_EQUAL flags
+   as described in Section 2.0 are valid.
+
+  
+void SetupForSolidFill(ScrnInfoPtr pScrn, 
+                       int color, int rop, unsigned int planemask)
+
+    SetupForSolidFill indicates that any combination of the following 
+    may follow it.
+
+	SubsequentSolidFillRect
+	SubsequentSolidFillTrap
+
+
+ 
+void SubsequentSolidFillRect(ScrnInfoPtr pScrn, int x, int y, int w, int h)
+
+     Fill a rectangle of dimensions "w" by "h" with origin at (x,y) 
+     using the color, rop and planemask given by the last 
+     SetupForSolidFill call.
+
+void SubsequentSolidFillTrap(ScrnInfoPtr pScrn, int y, int h, 
+	int left, int dxL, int dyL, int eL,
+	int right, int dxR, int dyR, int eR)
+
+     These parameters describe a trapezoid via a version of
+     Bresenham's parameters. "y" is the top line. "h" is the
+     number of spans to be filled in the positive Y direction.
+     "left" and "right" indicate the starting X values of the
+     left and right edges.  dy/dx describes the edge slope.
+     These are not the deltas between the beginning and ending
+     points on an edge.  They merely describe the slope. "e" is
+     the initial error term.  It's the relationships between dx,
+     dy and e that define the edge.
+	If your engine does not do bresenham trapezoids or does
+     not allow the programmer to specify the error term then
+     you are not expected to be able to accelerate them.
+
+
+2.3  Solid Lines
+
+    XAA provides an interface for drawing thin lines.  In order to
+    draw X lines correctly a high degree of accuracy is required.
+    This usually limits line acceleration to hardware which has a
+    Bresenham line engine, though depending on the algorithm used,
+    other line engines may come close if they accept 16 bit line 
+    deltas.  XAA has both a Bresenham line interface and a two-point
+    line interface for drawing lines of arbitrary orientation.  
+    Additionally there is a SubsequentSolidHorVertLine which will
+    be used for all horizontal and vertical lines.  Horizontal and
+    vertical lines are handled separately since hardware that doesn't
+    have a line engine (or has one that is unusable due to precision
+    problems) can usually draw these lines by some other method such
+    as drawing them as thin rectangles.  Even for hardware that can
+    draw arbitrary lines via the Bresenham or two-point interfaces,
+    the SubsequentSolidHorVertLine is used for horizontal and vertical
+    lines since most hardware is able to render the horizontal lines
+    and sometimes the vertical lines faster by other methods (Hint:
+    try rendering horizontal lines as flattened rectangles).  If you have 
+    not provided a SubsequentSolidHorVertLine but you have provided 
+    Bresenham or two-point lines, a SubsequentSolidHorVertLine function 
+    will be supplied for you.
+
+    The flags field associated with Solid Lines is SolidLineFlags and 
+    the GXCOPY_ONLY, ROP_NEEDS_SOURCE, NO_PLANEMASK and RGB_EQUAL flags as
+    described in Section 2.0 are valid restrictions.  
+
+    Some line engines have line biases hardcoded to comply with
+    Microsoft line biasing rules.  A tell-tale sign of this is the
+    hardware lines not matching the software lines in the zeroth and
+    fourth octants.  The driver can set the flag:
+	
+	MICROSOFT_ZERO_LINE_BIAS
+
+    in the AccelInfoRec.Flags field to adjust the software lines to
+    match the hardware lines.   This is in the generic flags field
+    rather than the SolidLineFlags since this flag applies to all
+    software zero-width lines on the screen and not just the solid ones.
+
+
+void SetupForSolidLine(ScrnInfoPtr pScrn, 
+                       int color, int rop, unsigned int planemask)
+
+    SetupForSolidLine indicates that any combination of the following 
+    may follow it.
+
+	SubsequentSolidBresenhamLine
+	SubsequentSolidTwoPointLine
+        SubsequentSolidHorVertLine 	
+
+
+void SubsequentSolidHorVertLine( ScrnInfoPtr pScrn,
+        			int x, int y, int len, int dir )
+
+    All vertical and horizontal solid thin lines are rendered with
+    this function.  The line starts at coordinate (x,y) and extends
+    "len" pixels inclusive.  In the direction indicated by "dir."
+    The direction is either DEGREES_O or DEGREES_270.  That is, it
+    always extends to the right or down.
+
+
+
+void SubsequentSolidTwoPointLine(ScrnInfoPtr pScrn,
+        	int x1, int y1, int x2, int y2, int flags)
+
+    Draw a line from (x1,y1) to (x2,y2).  If the flags field contains
+    the flag OMIT_LAST, the last pixel should not be drawn.  Otherwise,
+    the pixel at (x2,y2) should be drawn.
+
+    If you use the TwoPoint line interface there is a good possibility
+    that your line engine has hard-coded line biases that do not match
+    the default X zero-width lines.  If so, you may need to set the
+    MICROSOFT_ZERO_LINE_BIAS flag described above.  Note that since
+    any vertex in the 16-bit signed coordinate system is valid, your
+    line engine is expected to handle 16-bit values if you have hardware
+    line clipping enabled.  If your engine cannot handle 16-bit values,
+    you should not use hardware line clipping.
+
+
+void SubsequentSolidBresenhamLine(ScrnInfoPtr pScrn,
+        int x, int y, int major, int minor, int err, int len, int octant)
+
+    "X" and "y" are the starting point of the line.  "Major" and "minor" 
+    are the major and minor step constants.  "Err" is the initial error
+    term.  "Len" is the number of pixels to be drawn (inclusive). "Octant"
+    can be any combination of the following flags OR'd together:
+
+      Y_MAJOR		Y is the major axis (X otherwise)
+      X_DECREASING	The line is drawn from right to left
+      Y_DECREASING	The line is drawn from bottom to top
+	  
+    The major, minor and err terms are the "raw" Bresenham parameters
+    consistent with a line engine that does:
+
+	e = err;
+	while(len--) {
+	   DRAW_POINT(x,y);
+	   e += minor;
+	   if(e >= 0) {
+		e -= major;
+		TAKE_ONE_STEP_ALONG_MINOR_AXIS;
+	   }
+	   TAKE_ONE_STEP_ALONG_MAJOR_AXIS;
+	}
+
+    IBM 8514 style Bresenham line interfaces require their parameters
+    modified in the following way:
+
+	Axial = minor;
+	Diagonal = minor - major;
+	Error = minor + err;
+
+SolidBresenhamLineErrorTermBits
+
+    This field allows the driver to tell XAA how many bits large its
+    Bresenham parameter registers are.  Many engines have registers that
+    only accept 12 or 13 bit Bresenham parameters, and the parameters
+    for clipped lines may overflow these if they are not scaled down.
+    If this field is not set, XAA will assume the engine can accomodate
+    16 bit parameters, otherwise, it will scale the parameters to the
+    size specified.
+
+
+2.4  Dashed Lines
+
+    The same degree of accuracy required by the solid lines is required
+    for drawing dashed lines as well.  The dash pattern itself is a
+    buffer of binary data where ones are expanded into the foreground
+    color and zeros either correspond to the background color or
+    indicate transparency depending on whether or not DoubleDash or
+    OnOffDashes are being drawn.  
+
+    The flags field associated with dashed Lines is DashedLineFlags and 
+    the GXCOPY_ONLY, ROP_NEEDS_SOURCE, NO_PLANEMASK and RGB_EQUAL flags as
+    described in Section 2.0 are valid restrictions.  Additionally, the
+    following flags are valid:
+
+      NO_TRANSPARENCY
+
+	This indicates that the driver cannot support dashed lines
+	with transparent backgrounds (OnOffDashes).
+
+      TRANSPARENCY_ONLY
+
+	This indicates that the driver cannot support dashes with
+	both a foreground and background color (DoubleDashes).
+
+      LINE_PATTERN_POWER_OF_2_ONLY
+
+	This indicates that only patterns with a power of 2 length
+	can be accelerated.
+
+      LINE_PATTERN_LSBFIRST_MSBJUSTIFIED
+      LINE_PATTERN_LSBFIRST_LSBJUSTIFIED
+      LINE_PATTERN_MSBFIRST_MSBJUSTIFIED
+      LINE_PATTERN_MSBFIRST_LSBJUSTIFIED
+
+	These describe how the line pattern should be packed.
+	The pattern buffer is DWORD padded.  LSBFIRST indicates
+	that the pattern runs from the LSB end to the MSB end.
+	MSBFIRST indicates that the pattern runs from the MSB end
+	to the LSB end.  When the pattern does not completely fill
+	the DWORD padded buffer, the pattern will be justified 
+	towards the MSB or LSB end based on the flags above.
+
+
+    The following field indicates the maximum length dash pattern that
+    should be accelerated.
+
+	int DashPatternMaxLength
+
+
+void SetupForDashedLine(ScrnInfoPtr pScrn,
+		int fg, int bg, int rop, unsigned int planemask,
+        	int length, unsigned char *pattern)
+
+    
+    SetupForDashedLine indicates that any combination of the following 
+    may follow it.
+
+	SubsequentDashedBresenhamLine
+	SubsequentDashedTwoPointLine
+
+    If "bg" is -1, then the background (pixels corresponding to clear
+    bits in the pattern) should remain unmodified. "Bg" indicates the
+    background color otherwise.  "Length" indicates the length of
+    the pattern in bits and "pattern" points to the DWORD padded buffer
+    holding the pattern which has been packed according to the flags
+    set above.  
+
+    
+void SubsequentDashedTwoPointLine( ScrnInfoPtr pScrn,
+        int x1, int y1, int x2, int y2, int flags, int phase)
+
+void SubsequentDashedBresenhamLine(ScrnInfoPtr pScrn,
+        int x1, int y1, int major, int minor, int err, int len, int octant,
+        int phase)
+  
+    These are the same as the SubsequentSolidTwoPointLine and
+    SubsequentBresenhamLine functions except for the addition
+    of the "phase" field which indicates the offset into the dash 
+    pattern that the pixel at (x1,y1) corresponds to.
+
+    As with the SubsequentBresenhamLine, there is an
+ 
+	int DashedBresenhamLineErrorTermBits 
+   
+    field which indicates the size of the error term registers
+    used with dashed lines.  This is usually the same value as
+    the field for the solid lines (because it's usually the same
+    register).
+       
+      
+
+2.5   Color Expansion Fills
+
+    When filling a color expansion rectangle, the accelerator
+    paints each pixel depending on whether or not a bit in a
+    corresponding bitmap is set or clear. Opaque expansions are 
+    when a set bit corresponds to the foreground color and a clear 
+    bit corresponds to the background color.  A transparent expansion
+    is when a set bit corresponds to the foreground color and a
+    clear bit indicates that the pixel should remain unmodified.
+   
+    The graphics accelerator usually has access to the source 
+    bitmap in one of two ways: 1) the bitmap data is sent serially
+    to the accelerator by the CPU through some memory mapped aperture
+    or 2) the accelerator reads the source bitmap out of offscreen
+    video memory.  Some types of primitives are better suited towards 
+    one method or the other.  Type 2 is useful for reusable patterns
+    such as stipples which can be cached in offscreen memory.  The
+    aperature method can be used for stippling but the CPU must pass
+    the data across the bus each time a stippled fill is to be performed.  
+    For expanding 1bpp client pixmaps or text strings to the screen,
+    the aperature method is usually superior because the intermediate
+    copy in offscreen memory needed by the second method would only be 
+    used once.  Unfortunately, many accelerators can only do one of these
+    methods and not both.  
+
+    XAA provides both ScreenToScreen and CPUToScreen color expansion 
+    interfaces for doing color expansion fills.  The ScreenToScreen
+    functions can only be used with hardware that supports reading
+    of source bitmaps from offscreen video memory, and these are only
+    used for cacheable patterns such as stipples.  There are two
+    variants of the CPUToScreen routines - a direct method intended
+    for hardware that has a transfer aperature, and an indirect method
+    intended for hardware without transfer aperatures or hardware
+    with unusual transfer requirements.  Hardware that can only expand
+    bitmaps from video memory should supply ScreenToScreen routines
+    but also ScanlineCPUToScreen (indirect) routines to optimize transfers 
+    of non-cacheable data.  Hardware that can only accept source bitmaps
+    through an aperature should supply CPUToScreen (or ScanlineCPUToScreen) 
+    routines. Hardware that can do both should provide both ScreenToScreen 
+    and CPUToScreen routines.
+
+    For both ScreenToScreen and CPUToScreen interfaces, the GXCOPY_ONLY,
+    ROP_NEEDS_SOURCE, NO_PLANEMASK and RGB_EQUAL flags described in
+    Section 2.0 are valid as well as the following:
+
+    /* bit order requirements (one of these must be set) */
+   
+    BIT_ORDER_IN_BYTE_LSBFIRST
+
+      This indicates that least significant bit in each byte of the source
+      data corresponds to the leftmost of that block of 8 pixels.  This
+      is the prefered format.
+
+    BIT_ORDER_IN_BYTE_MSBFIRST    
+
+      This indicates that most significant bit in each byte of the source
+      data corresponds to the leftmost of that block of 8 pixels.
+
+    /* transparency restrictions */
+
+    NO_TRANSPARENCY
+
+      This indicates that the accelerator cannot do a transparent expansion.
+
+    TRANSPARENCY_ONLY
+
+      This indicates that the accelerator cannot do an opaque expansion.
+      In cases where where the background needs to be filled, XAA will
+      render the primitive in two passes when using the CPUToScreen
+      interface, but will not do so with the ScreenToScreen interface 
+      since that would require caching of two patterns.  Some 
+      ScreenToScreen hardware may be able to render two passes at the
+      driver level and remove the TRANSPARENCY_ONLY restriction if
+      it can render pixels corresponding to the zero bits.
+
+
+
+2.5.1  Screen To Screen Color Expansion
+
+    The ScreenToScreenColorExpandFill routines provide an interface
+    for doing expansion blits from source patterns stored in offscreen
+    video memory.
+
+    void SetupForScreenToScreenColorExpandFill (ScrnInfoPtr pScrn,
+        			int fg, int bg, 
+				int rop, unsigned int planemask)
+
+
+    Ones in the source bitmap will correspond to the fg color.
+    Zeros in the source bitmap will correspond to the bg color
+    unless bg = -1.  In that case the pixels corresponding to the
+    zeros in the bitmap shall be left unmodified by the accelerator.
+
+    For hardware that doesn't allow an easy implementation of skipleft, the
+    driver can replace CacheMonoStipple function with one that stores multiple
+    rotated copies of the stipple and select between them. In this case the
+    driver should set CacheColorExpandDensity to tell XAA how many copies of
+    the pattern are stored in the width of a cache slot. For instance if the
+    hardware can specify the starting address in bytes, then 8 rotated copies
+    of the stipple are needed and CacheColorExpandDensity should be set to 8.
+
+    void SubsequentScreenToScreenColorExpandFill( ScrnInfoPtr pScrn,
+				int x, int y, int w, int h,
+				int srcx, int srcy, int offset )
+
+   
+    Fill a rectangle "w" x "h" at location (x,y).  The source pitch
+    between scanlines is the framebuffer pitch (pScrn->displayWidth
+    pixels) and srcx and srcy indicate the start of the source pattern 
+    in units of framebuffer pixels. "Offset" indicates the bit offset
+    into the pattern that corresponds to the pixel being painted at
+    "x" on the screen.  Some hardware accepts source coordinates in
+    units of bits which makes implementation of the offset trivial.
+    In that case, the bit address of the source bit corresponding to
+    the pixel painted at (x,y) would be:
+	
+     (srcy * pScrn->displayWidth + srcx) * pScrn->bitsPerPixel + offset
+
+    It should be noted that the offset assumes LSBFIRST hardware.  
+    For MSBFIRST hardware, the driver may need to implement the 
+    offset by bliting only from byte boundaries and hardware clipping.
+
+
+
+2.5.2  CPU To Screen Color Expansion
+
+
+    The CPUToScreenColorExpandFill routines provide an interface for 
+    doing expansion blits from source patterns stored in system memory.
+    There are two varieties of this primitive, a CPUToScreenColorExpandFill
+    and a ScanlineCPUToScreenColorExpandFill.  With the 
+    CPUToScreenColorExpandFill method, the source data is sent serially
+    through a memory mapped aperature.  With the Scanline version, the
+    data is rendered scanline at a time into intermediate buffers with
+    a call to SubsequentColorExpandScanline following each scanline.
+
+    These two methods have separate flags fields, the
+    CPUToScreenColorExpandFillFlags and ScanlineCPUToScreenColorExpandFillFlags
+    respectively.  Flags specific to one method or the other are described 
+    in sections 2.5.2.1 and 2.5.2.2 but for both cases the bit order and
+    transparency restrictions listed at the beginning of section 2.5 are 
+    valid as well as the following:
+    
+    /* clipping  (optional) */
+    
+    LEFT_EDGE_CLIPPING
+ 
+      This indicates that the accelerator supports omission of up to
+      31 pixels on the left edge of the rectangle to be filled.  This
+      is beneficial since it allows transfer of the source bitmap to
+      always occur from DWORD boundaries. 
+
+    LEFT_EDGE_CLIPPING_NEGATIVE_X
+
+      This flag indicates that the accelerator can render color expansion
+      rectangles even if the value of x origin is negative (off of
+      the screen on the left edge).
+
+    /* misc */
+
+    TRIPLE_BITS_24BPP
+
+      When enabled (must be in 24bpp mode), color expansion functions
+      are expected to require three times the amount of bits to be
+      transferred so that 24bpp grayscale colors can be used with color
+      expansion in 8bpp coprocessor mode. Each bit is expanded to 3
+      bits when writing the monochrome data.
+
+
+ 2.5.1 The Direct Method 
+
+
+    Using the direct method of color expansion XAA will send all
+    bitmap data to the accelerator serially through an memory mapped
+    transfer window defined by the following two fields:
+
+      unsigned char *ColorExpandBase
+
+        This indicates the memory address of the beginning of the aperture.
+
+      int ColorExpandRange
+
+        This indicates the size in bytes of the aperture.
+
+    The driver should specify how the transfered data should be padded.
+    There are options for both the padding of each Y scanline and for the
+    total transfer to the aperature.
+    One of the following two flags must be set:
+
+      CPU_TRANSFER_PAD_DWORD
+
+        This indicates that the total transfer (sum of all scanlines) sent
+        to the aperature must be DWORD padded.  This is the default behavior.
+
+      CPU_TRANSFER_PAD_QWORD 
+
+	This indicates that the total transfer (sum of all scanlines) sent
+	to the aperature must be QWORD padded.  With this set, XAA will send
+        an extra DWORD to the aperature when needed to ensure that only
+        an even number of DWORDs are sent.
+
+    And then there are the flags for padding of each scanline:
+
+      SCANLINE_PAD_DWORD
+
+	This indicates that each Y scanline should be DWORD padded.
+        This is the only option available and is the default.
+
+    Finally, there is the CPU_TRANSFER_BASE_FIXED flag which indicates
+    that the aperture is a single register rather than a range of
+    registers, and XAA should write all of the data to the first DWORD.
+    If the ColorExpandRange is not large enough to accomodate scanlines
+    the width of the screen, this option will be forced. That is, the
+    ColorExpandRange must be:
+
+        ((virtualX + 31)/32) * 4   bytes or more.
+
+        ((virtualX + 62)/32 * 4) if LEFT_EDGE_CLIPPING_NEGATIVE_X is set.
+  
+    If the TRIPLE_BITS_24BPP flag is set, the required area should be 
+    multiplied by three.
+     
+    
+void SetupForCPUToScreenColorExpandFill(ScrnInfoPtr pScrn,
+        		int fg, int bg,
+			int rop,
+			unsigned int planemask)
+
+  
+ 
+     Ones in the source bitmap will correspond to the fg color.
+     Zeros in the source bitmap will correspond to the bg color
+     unless bg = -1.  In that case the pixels corresponding to the
+     zeros in the bitmap shall be left unmodified by the accelerator.
+
+
+void SubsequentCPUToScreenColorExpandFill(ScrnInfoPtr pScrn,
+			int x, int y, int w, int h,
+			int skipleft )
+
+     When this function is called, the accelerator should be setup
+     to fill a rectangle of dimension "w" by "h" with origin at (x,y)
+     in the fill style prescribed by the last call to 
+     SetupForCPUToScreenColorExpandFill.  XAA will pass the data to 
+     the aperture immediately after this function is called.  If the 
+     skipleft is non-zero (and LEFT_EDGE_CLIPPING has been enabled), then 
+     the accelerator _should_not_ render skipleft pixels on the leftmost
+     edge of the rectangle.  Some engines have an alignment feature
+     like this built in, some others can do this using a clipping
+     window.
+
+     It can be arranged for XAA to call Sync() after it is through 
+     calling the Subsequent function by setting SYNC_AFTER_COLOR_EXPAND 
+     in the  CPUToScreenColorExpandFillFlags.  This can provide the driver 
+     with an oportunity to reset a clipping window if needed.
+
+    
+2.5.2  The Indirect Method 
+
+     Using the indirect method, XAA will render the bitmap data scanline
+     at a time to one or more buffers.  These buffers may be memory
+     mapped apertures or just intermediate storage.
+
+     int NumScanlineColorExpandBuffers
+
+       This indicates the number of buffers available.
+
+     unsigned char **ScanlineColorExpandBuffers
+
+       This is an array of pointers to the memory locations of each buffer.
+       Each buffer is expected to be large enough to accommodate scanlines
+       the width of the screen.  That is:
+
+        ((virtualX + 31)/32) * 4   bytes or more.
+
+        ((virtualX + 62)/32 * 4) if LEFT_EDGE_CLIPPING_NEGATIVE_X is set.
+  
+     Scanlines are always DWORD padded.
+     If the TRIPLE_BITS_24BPP flag is set, the required area should be 
+     multiplied by three.
+
+
+void SetupForScanlineCPUToScreenColorExpandFill(ScrnInfoPtr pScrn,
+        		int fg, int bg,
+			int rop,
+			unsigned int planemask)
+ 
+     Ones in the source bitmap will correspond to the fg color.
+     Zeros in the source bitmap will correspond to the bg color
+     unless bg = -1.  In that case the pixels corresponding to the
+     zeros in the bitmap shall be left unmodified by the accelerator.
+
+     
+void SubsequentScanlineCPUToScreenColorExpandFill(ScrnInfoPtr pScrn,
+			int x, int y, int w, int h,
+			int skipleft )
+
+void SubsequentColorExpandScanline(ScrnInfoPtr pScrn, int bufno)
+
+
+    When SubsequentScanlineCPUToScreenColorExpandFill is called, XAA 
+    will begin transfering the source data scanline at a time, calling  
+    SubsequentColorExpandScanline after each scanline.  If more than
+    one buffer is available, XAA will cycle through the buffers.
+    Subsequent scanlines will use the next buffer and go back to the
+    buffer 0 again when the last buffer is reached.  The index into
+    the ScanlineColorExpandBuffers array is presented as "bufno"
+    with each SubsequentColorExpandScanline call.
+
+    The skipleft field is the same as for the direct method.
+
+    The indirect method can be use to send the source data directly 
+    to a memory mapped aperture represented by a single color expand
+    buffer, scanline at a time, but more commonly it is used to place 
+    the data into offscreen video memory so that the accelerator can 
+    blit it to the visible screen from there.  In the case where the
+    accelerator permits rendering into offscreen video memory while
+    the accelerator is active, several buffers can be used so that
+    XAA can be placing source data into the next buffer while the
+    accelerator is blitting the current buffer.  For cases where
+    the accelerator requires some special manipulation of the source
+    data first, the buffers can be in system memory.  The CPU can
+    manipulate these buffers and then send the data to the accelerator.
+
+
+
+2.6   8x8 Mono Pattern Fills
+
+    XAA provides support for two types of 8x8 hardware patterns -
+    "Mono" patterns and "Color" patterns.  Mono pattern data is
+    64 bits of color expansion data with ones indicating the
+    foreground color and zeros indicating the background color.
+    The source bitmaps for the 8x8 mono patterns can be presented
+    to the graphics accelerator in one of two ways.  They can be
+    passed as two DWORDS to the 8x8 mono pattern functions or
+    they can be cached in offscreen memory and their locations
+    passed to the 8x8 mono pattern functions.  In addition to the
+    GXCOPY_ONLY, ROP_NEEDS_SOURCE, NO_PLANEMASK and RGB_EQUAL flags
+    defined in Section 2.0, the following are defined for the
+    Mono8x8PatternFillFlags:
+
+    HARDWARE_PATTERN_PROGRAMMED_BITS
+
+      This indicates that the 8x8 patterns should be packed into two
+      DWORDS and passed to the 8x8 mono pattern functions.  The default
+      behavior is to cache the patterns in offscreen video memory and
+      pass the locations of these patterns to the functions instead.
+      The pixmap cache must be enabled for the default behavior (8x8 
+      pattern caching) to work.  See Section 3 for how to enable the
+      pixmap cache. The pixmap cache is not necessary for 
+      HARDWARE_PATTERN_PROGRAMMED_BITS.
+
+    HARDWARE_PATTERN_PROGRAMMED_ORIGIN
+
+      If the hardware supports programmable pattern offsets then
+      this option should be set. See the table below for further
+      infomation.
+
+    HARDWARE_PATTERN_SCREEN_ORIGIN
+
+      Some hardware wants the pattern offset specified with respect to the
+      upper left-hand corner of the primitive being drawn.  Other hardware 
+      needs the option HARDWARE_PATTERN_SCREEN_ORIGIN set to indicate that 
+      all pattern offsets should be referenced to the upper left-hand 
+      corner of the screen.  HARDWARE_PATTERN_SCREEN_ORIGIN is preferable 
+      since this is more natural for the X-Window system and offsets will 
+      have to be recalculated for each Subsequent function otherwise.
+
+    BIT_ORDER_IN_BYTE_MSBFIRST
+    BIT_ORDER_IN_BYTE_LSBFIRST
+
+      As with other color expansion routines this indicates whether the
+      most or the least significant bit in each byte from the pattern is 
+      the leftmost on the screen.
+
+    TRANSPARENCY_ONLY
+    NO_TRANSPARENCY
+
+      This means the same thing as for the color expansion rect routines
+      except that for TRANSPARENCY_ONLY XAA will not render the primitive
+      in two passes since this is more easily handled by the driver.
+      It is recommended that TRANSPARENCY_ONLY hardware handle rendering
+      of opaque patterns in two passes (the background can be filled as
+      a rectangle in GXcopy) in the Subsequent function so that the
+      TRANSPARENCY_ONLY restriction can be removed. 
+
+
+
+    Additional information about cached patterns...
+    For the case where HARDWARE_PATTERN_PROGRAMMED_BITS is not set and 
+    the pattern must be cached in offscreen memory, the first pattern
+    starts at the cache slot boundary which is set by the 
+    CachePixelGranularity field used to configure the pixmap cache.
+    One should ensure that the CachePixelGranularity reflects any 
+    alignment restrictions that the accelerator may put on 8x8 pattern 
+    storage locations.  When HARDWARE_PATTERN_PROGRAMMED_ORIGIN is set 
+    there is only one pattern stored.  When this flag is not set,
+    all 64 pre-rotated copies of the pattern are cached in offscreen memory.
+    The MonoPatternPitch field can be used to specify the X position pixel
+    granularity that each of these patterns must align on.  If the
+    MonoPatternPitch is not supplied, the patterns will be densely packed
+    within the cache slot.  The behavior of the default XAA 8x8 pattern
+    caching mechanism to store all 8x8 patterns linearly in video memory.
+    If the accelerator needs the patterns stored in a more unusual fashion,
+    the driver will need to provide its own 8x8 mono pattern caching 
+    routines for XAA to use. 
+
+    The following table describes the meanings of the "patx" and "paty"
+    fields in both the SetupFor and Subsequent functions.
+
+    With HARDWARE_PATTERN_SCREEN_ORIGIN
+    -----------------------------------
+
+    HARDWARE_PATTERN_PROGRAMMED_BITS and HARDWARE_PATTERN_PROGRAMMED_ORIGIN
+
+	SetupFor: patx and paty are the first and second DWORDS of the
+		  8x8 mono pattern.
+
+	Subsequent: patx and paty are the x,y offset into that pattern.
+		    All Subsequent calls will have the same offset in 
+		    the case of HARDWARE_PATTERN_SCREEN_ORIGIN so only
+		    the offset specified by the first Subsequent call 
+		    after a SetupFor call will need to be observed.
+
+    HARDWARE_PATTERN_PROGRAMMED_BITS only
+
+	SetupFor: patx and paty hold the first and second DWORDS of
+		  the 8x8 mono pattern pre-rotated to match the desired
+		  offset.
+
+	Subsequent: These just hold the same patterns and can be ignored.
+
+    HARDWARE_PATTERN_PROGRAMMED_ORIGIN only
+
+	SetupFor: patx and paty hold the x,y coordinates of the offscreen
+		  memory location where the 8x8 pattern is stored.  The
+		  bits are stored linearly in memory at that location.
+
+	Subsequent: patx and paty hold the offset into the pattern.
+		    All Subsequent calls will have the same offset in 
+		    the case of HARDWARE_PATTERN_SCREEN_ORIGIN so only
+		    the offset specified by the first Subsequent call 
+		    after a SetupFor call will need to be observed.
+
+    Neither programmed bits or origin
+
+	SetupFor: patx and paty hold the x,y coordinates of the offscreen 	
+		  memory location where the pre-rotated 8x8 pattern is
+		  stored.
+
+	Subsequent: patx and paty are the same as in the SetupFor function
+		    and can be ignored.
+		  
+
+    Without HARDWARE_PATTERN_SCREEN_ORIGIN
+    -------------------------------------- 
+
+    HARDWARE_PATTERN_PROGRAMMED_BITS and HARDWARE_PATTERN_PROGRAMMED_ORIGIN

+
+
+2.7   8x8 Color Pattern Fills
+  
+    8x8 color pattern data is 64 pixels of full color data that
+    is stored linearly in offscreen video memory.  8x8 color patterns 
+    are useful as a substitute for 8x8 mono patterns when tiling,
+    doing opaque stipples, or in the case where transperency is
+    supported, regular stipples.  8x8 color pattern fills also have
+    the additional benefit of being able to tile full color 8x8
+    patterns instead of just 2 color ones like the mono patterns.
+    However, full color 8x8 patterns aren't used very often in the
+    X Window system so you might consider passing this primitive
+    by if you already can do mono patterns, especially if they 
+    require alot of cache area.  Color8x8PatternFillFlags is
+    the flags field for this primitive and the GXCOPY_ONLY,
+    ROP_NEEDS_SOURCE and NO_PLANEMASK flags as described in
+    Section 2.0 are valid as well as the following:
+
+
+    HARDWARE_PATTERN_PROGRAMMED_ORIGIN
+
+      If the hardware supports programmable pattern offsets then
+      this option should be set.  
+
+    HARDWARE_PATTERN_SCREEN_ORIGIN
+
+      Some hardware wants the pattern offset specified with respect to the
+      upper left-hand corner of the primitive being drawn.  Other hardware 
+      needs the option HARDWARE_PATTERN_SCREEN_ORIGIN set to indicate that 
+      all pattern offsets should be referenced to the upper left-hand 
+      corner of the screen.  HARDWARE_PATTERN_SCREEN_ORIGIN is preferable 
+      since this is more natural for the X-Window system and offsets will 
+      have to be recalculated for each Subsequent function otherwise.
+
+    NO_TRANSPARENCY
+    TRANSPARENCY_GXCOPY_ONLY
+
+      These mean the same as for the ScreenToScreenCopy functions.
+
+
+    The following table describes the meanings of patx and paty passed
+    to the SetupFor and Subsequent fields:
+
+    HARDWARE_PATTERN_PROGRAMMED_ORIGIN && HARDWARE_PATTERN_SCREEN_ORIGIN
+	
+	SetupFor: patx and paty hold the x,y location of the unrotated 
+		  pattern.
+
+	Subsequent: patx and paty hold the pattern offset.  For the case
+		    of HARDWARE_PATTERN_SCREEN_ORIGIN all Subsequent calls
+		    have the same offset so only the first call will need
+		    to be observed.
+
+    
+    HARDWARE_PATTERN_PROGRAMMED_ORIGIN only
+
+	SetupFor: patx and paty hold the x,y location of the unrotated
+		  pattern.
+
+	Subsequent: patx and paty hold the pattern offset. 
+
+    HARDWARE_PATTERN_SCREEN_ORIGIN
+
+	SetupFor: patx and paty hold the x,y location of the rotated pattern.
+
+	Subsequent: patx and paty hold the same location as the SetupFor
+		    function so these can be ignored.
+
+    neither flag
+
+	SetupFor: patx and paty hold the x,y location of the unrotated
+		  pattern.  This can be ignored.
+
+	Subsequent: patx and paty hold the x,y location of the rotated
+		    pattern.
+
+    Additional information about cached patterns...
+    All 8x8 color patterns are cached in offscreen video memory so
+    the pixmap cache must be enabled to use them. The first pattern
+    starts at the cache slot boundary which is set by the 
+    CachePixelGranularity field used to configure the pixmap cache.
+    One should ensure that the CachePixelGranularity reflects any 
+    alignment restrictions that the accelerator may put on 8x8 pattern 
+    storage locations.  When HARDWARE_PATTERN_PROGRAMMED_ORIGIN is set 
+    there is only one pattern stored.  When this flag is not set,
+    all 64 rotations off the pattern are accessible but it is assumed
+    that the accelerator is capable of accessing data stored on 8
+    pixel boundaries.  If the accelerator has stricter alignment 
+    requirements than this the dirver will need to provide its own 
+    8x8 color pattern caching routines. 
+
+
+void SetupForColor8x8PatternFill(ScrnInfoPtr pScrn, int patx, int paty,
+        	int rop, unsigned int planemask, int trans_color)
+
+    SetupForColor8x8PatternFill indicates that any combination of the 
+    following  may follow it.
+
+	SubsequentColor8x8PatternFillRect
+	SubsequentColor8x8PatternFillTrap	(not implemented yet)
+
+    For the meanings of patx and paty, see the table above.  Trans_color
+    means the same as for the ScreenToScreenCopy functions.
+
+
+ 
+void SubsequentColor8x8PatternFillRect( ScrnInfoPtr pScrn,
+        	int patx, int paty, int x, int y, int w, int h)
+
+     Fill a rectangle of dimensions "w" by "h" with origin at (x,y) 
+     using the parameters give by the last SetupForColor8x8PatternFill
+     call.  The meanings of patx and paty can be determined by the
+     table above.
+
+void SubsequentColor8x8PatternFillTrap( ScrnInfoPtr pScrn,
+     			   int patx, int paty, int y, int h,

+    The rest of the fields have the same meanings as those in the 
+    SubsequentSolidFillTrap function. 
+
+
+
+2.8  Image Writes
+
+    XAA provides a mechanism for transfering full color pixel data from
+    system memory to video memory through the accelerator.  This is 
+    useful for dealing with alignment issues and performing raster ops
+    on the data when writing it to the framebuffer.  As with color
+    expansion rectangles, there is a direct and indirect method.  The
+    direct method sends all data through a memory mapped aperature.
+    The indirect method sends the data to an intermediated buffer scanline 
+    at a time.
+
+    The direct and indirect methods have separate flags fields, the
+    ImageWriteFlags and ScanlineImageWriteFlags respectively.
+    Flags specific to one method or the other are described in sections 
+    2.8.1 and 2.8.2 but for both cases the GXCOPY_ONLY, ROP_NEEDS_SOURCE
+    and NO_PLANEMASK flags described in Section 2.0 are valid as well as
+    the following:
+
+    NO_GXCOPY
+
+      In order to have accelerated image transfers faster than the 
+      software versions for GXcopy, the engine needs to support clipping,
+      be using the direct method and have a large enough image transfer
+      range so that CPU_TRANSFER_BASE_FIXED doesn't need to be set.
+      If these are not supported, then it is unlikely that transfering
+      the data through the accelerator will be of any advantage for the
+      simple case of GXcopy.  In fact, it may be much slower.  For such
+      cases it's probably best to set the NO_GXCOPY flag so that 
+      Image writes will only be used for the more complicated rops.
+
+    /* transparency restrictions */
+
+    NO_TRANSPARENCY
+     
+      This indicates that the accelerator does not support skipping
+      of color keyed pixels when copying from the source to the destination.
+
+    TRANSPARENCY_GXCOPY_ONLY
+
+      This indicates that the accelerator supports skipping of color keyed
+      pixels only when the rop is GXcopy.
+
+    /* clipping  (optional) */
+    
+    LEFT_EDGE_CLIPPING
+ 
+      This indicates that the accelerator supports omission of up to
+      3 pixels on the left edge of the rectangle to be filled.  This
+      is beneficial since it allows transfer from the source pixmap to
+      always occur from DWORD boundaries. 
+
+    LEFT_EDGE_CLIPPING_NEGATIVE_X
+
+      This flag indicates that the accelerator can fill areas with
+      image write data even if the value of x origin is negative (off of
+      the screen on the left edge).
+
+
+2.8.1 The Direct Method
+
+    Using the direct method of ImageWrite XAA will send all
+    bitmap data to the accelerator serially through an memory mapped
+    transfer window defined by the following two fields:
+
+      unsigned char *ImageWriteBase
+
+        This indicates the memory address of the beginning of the aperture.
+
+      int ImageWriteRange
+
+        This indicates the size in bytes of the aperture.
+
+    The driver should specify how the transfered data should be padded.
+    There are options for both the padding of each Y scanline and for the
+    total transfer to the aperature.
+    One of the following two flags must be set:
+
+      CPU_TRANSFER_PAD_DWORD
+
+        This indicates that the total transfer (sum of all scanlines) sent
+        to the aperature must be DWORD padded.  This is the default behavior.
+
+      CPU_TRANSFER_PAD_QWORD 
+
+	This indicates that the total transfer (sum of all scanlines) sent
+	to the aperature must be QWORD padded.  With this set, XAA will send
+        an extra DWORD to the aperature when needed to ensure that only
+        an even number of DWORDs are sent.
+
+    And then there are the flags for padding of each scanline:
+
+      SCANLINE_PAD_DWORD
+
+	This indicates that each Y scanline should be DWORD padded.
+        This is the only option available and is the default.
+
+    Finally, there is the CPU_TRANSFER_BASE_FIXED flag which indicates
+    that the aperture is a single register rather than a range of
+    registers, and XAA should write all of the data to the first DWORD.
+    XAA will automatically select CPU_TRANSFER_BASE_FIXED if the 
+    ImageWriteRange is not large enough to accomodate an entire scanline.   
+
+
+void SetupForImageWrite(ScrnInfoPtr pScrn, int rop, unsigned int planemask,
+        			int trans_color, int bpp, int depth)
+
+     If trans_color is not -1 then trans_color indicates the transparency
+     color key and pixels with color trans_color passed through the 
+     aperature should not be transfered to the screen but should be 
+     skipped.  Bpp and depth indicate the bits per pixel and depth of
+     the source pixmap.  Trans_color is always -1 if the NO_TRANSPARENCY
+     flag is set.
+
+
+void SubsequentImageWriteRect(ScrnInfoPtr pScrn, 
+				int x, int y, int w, int h, int skipleft)
+
+     
+     Data passed through the aperature should be copied to a rectangle
+     of width "w" and height "h" with origin (x,y).  If LEFT_EDGE_CLIPPING
+     has been enabled, skipleft will correspond to the number of pixels
+     on the left edge that should not be drawn.  Skipleft is zero 
+     otherwise.
+
+     It can be arranged for XAA to call Sync() after it is through 
+     calling the Subsequent functions by setting SYNC_AFTER_IMAGE_WRITE 
+     in the  ImageWriteFlags.  This can provide the driver with an
+     oportunity to reset a clipping window if needed.
+
+2.8.2  The Indirect Method
+
+     Using the indirect method, XAA will render the pixel data scanline
+     at a time to one or more buffers.  These buffers may be memory
+     mapped apertures or just intermediate storage.
+
+     int NumScanlineImageWriteBuffers
+
+       This indicates the number of buffers available.
+
+     unsigned char **ScanlineImageWriteBuffers
+
+       This is an array of pointers to the memory locations of each buffer.
+       Each buffer is expected to be large enough to accommodate scanlines
+       the width of the screen.  That is:
+
+         pScrn->VirtualX * pScreen->bitsPerPixel/8   bytes or more.
+
+       If LEFT_EDGE_CLIPPING_NEGATIVE_X is set, add an additional 4
+       bytes to that requirement in 8 and 16bpp, 12 bytes in 24bpp.
+  
+     Scanlines are always DWORD padded.
+
+void SetupForScanlineImageWrite(ScrnInfoPtr pScrn, int rop, 
+				unsigned int planemask, int trans_color, 
+				int bpp, int depth)
+
+     If trans_color is not -1 then trans_color indicates the transparency
+     color key and pixels with color trans_color in the buffer should not 
+     be transfered to the screen but should be skipped.  Bpp and depth 
+     indicate the bits per pixel and depth of the source bitmap.  
+     Trans_color is always -1 if the NO_TRANSPARENCY flag is set.
+
+
+void SubsequentImageWriteRect(ScrnInfoPtr pScrn, 
+				int x, int y, int w, int h, int skipleft)
+
+     
+void SubsequentImageWriteScanline(ScrnInfoPtr pScrn, int bufno)
+
+
+    When SubsequentImageWriteRect is called, XAA will begin
+    transfering the source data scanline at a time, calling  
+    SubsequentImageWriteScanline after each scanline.  If more than
+    one buffer is available, XAA will cycle through the buffers.
+    Subsequent scanlines will use the next buffer and go back to the
+    buffer 0 again when the last buffer is reached.  The index into
+    the ScanlineImageWriteBuffers array is presented as "bufno"
+    with each SubsequentImageWriteScanline call.
+
+    The skipleft field is the same as for the direct method.
+
+    The indirect method can be use to send the source data directly 
+    to a memory mapped aperture represented by a single image write
+    buffer, scanline at a time, but more commonly it is used to place 
+    the data into offscreen video memory so that the accelerator can 
+    blit it to the visible screen from there.  In the case where the
+    accelerator permits rendering into offscreen video memory while
+    the accelerator is active, several buffers can be used so that
+    XAA can be placing source data into the next buffer while the
+    accelerator is blitting the current buffer.  For cases where
+    the accelerator requires some special manipulation of the source
+    data first, the buffers can be in system memory.  The CPU can
+    manipulate these buffers and then send the data to the accelerator.
+
+
+2.9 Clipping
+
+    XAA supports hardware clipping rectangles.  To use clipping
+    in this way it is expected that the graphics accelerator can
+    clip primitives with verticies anywhere in the 16 bit signed 
+    coordinate system. 
+
+void SetClippingRectangle ( ScrnInfoPtr pScrn,
+        		int left, int top, int right, int bottom)
+
+void DisableClipping (ScrnInfoPtr pScrn)
+
+    When SetClippingRectangle is called, all hardware rendering
+    following it should be clipped to the rectangle specified
+    until DisableClipping is called.
+
+    The ClippingFlags field indicates which operations this sort
+    of Set/Disable pairing can be used with.  Any of the following
+    flags may be OR'd together.
+
+	HARDWARE_CLIP_SCREEN_TO_SCREEN_COLOR_EXPAND
+	HARDWARE_CLIP_SCREEN_TO_SCREEN_COPY
+	HARDWARE_CLIP_MONO_8x8_FILL
+	HARDWARE_CLIP_COLOR_8x8_FILL
+	HARDWARE_CLIP_SOLID_FILL
+	HARDWARE_CLIP_DASHED_LINE
+	HARDWARE_CLIP_SOLID_LINE
+
+
+
+3)  XAA PIXMAP CACHE
+
+   /* NOTE:  XAA has no knowledge of framebuffer particulars so until
+	the framebuffer is able to render into offscreen memory, usage
+	of the pixmap cache requires that the driver provide ImageWrite
+	routines or a WritePixmap or WritePixmapToCache replacement so
+	that patterns can even be placed in the cache.
+
+      ADDENDUM: XAA can now load the pixmap cache without requiring
+	that the driver supply an ImageWrite function, but this can
+	only be done on linear framebuffers.  If you have a linear
+	framebuffer, set LINEAR_FRAMEBUFFER in the XAAInfoRec.Flags
+	field and XAA will then be able to upload pixmaps into the
+	cache without the driver providing functions to do so.
+   */
+
+
+   The XAA pixmap cache provides a mechanism for caching of patterns
+   in offscreen video memory so that tiled fills and in some cases
+   stippling can be done by blitting the source patterns from offscreen
+   video memory. The pixmap cache also provides the mechanism for caching 
+   of 8x8 color and mono hardware patterns.  Any unused offscreen video
+   memory gets used for the pixmap cache and that information is 
+   provided by the XFree86 Offscreen Memory Manager. XAA registers a 
+   callback with the manager so that it can be informed of any changes 
+   in the offscreen memory configuration.  The driver writer does not 
+   need to deal with any of this since it is all automatic.  The driver 
+   merely needs to initialize the Offscreen Memory Manager as described 
+   in the DESIGN document and set the PIXMAP_CACHE flag in the 
+   XAAInfoRec.Flags field.  The Offscreen Memory Manager initialization 
+   must occur before XAA is initialized or else pixmap cache 
+   initialization will fail.  
+
+   PixmapCacheFlags is an XAAInfoRec field which allows the driver to
+   control pixmap cache behavior to some extent.  Currently only one
+   flag is defined:
+
+   DO_NOT_BLIT_STIPPLES
+
+     This indicates that the stippling should not be done by blitting
+     from the pixmap cache.  This does not apply to 8x8 pattern fills. 
+
+
+   CachePixelGranularity is an optional field.  If the hardware requires
+   that a 8x8 patterns have some particular pixel alignment it should
+   be reflected in this field.  Ignoring this field or setting it to
+   zero or one means there are no alignment issues.
+
+
+4)  OFFSCREEN PIXMAPS
+
+   XAA has the ability to store pixmap drawables in offscreen video 
+   memory and render into them with full hardware acceleration.  Placement
+   of pixmaps in the cache is done automatically on a first-come basis and 
+   only if there is room.  To enable this feature, set the OFFSCREEN_PIXMAPS
+   flag in the XAAInfoRec.Flags field.  This is only available when a
+   ScreenToScreenCopy function is provided, when the Offscreen memory 
+   manager has been initialized and when the LINEAR_FRAMEBUFFER flag is
+   also set.
+
+   int maxOffPixWidth
+   int maxOffPixHeight
+
+       These two fields allow the driver to limit the maximum dimensions
+     of an offscreen pixmap.  If one of these is not set, it is assumed
+     that there is no limit on that dimension.  Note that if an offscreen
+     pixmap with a particular dimension is allowed, then your driver will be
+     expected to render primitives as large as that pixmap.

+
+   In this file we have GC level replacements for PolyText8/16,
+   ImageText8/16, ImageGlyphBlt and PolyGlyphBlt for NonTE (proportional) 
+   fonts. The idea is that everything in this file is device independent.
+   The mentioned GCOps are merely wrappers for the 
+   PolyGlyphBltNonTEColorExpansion and ImageGlyphBltNonTEColorExpansion
+   functions which calculate the boxes containing arbitrarily clipped 
+   text and passes them to the NonTEGlyphRenderer which will usually 
+   be a lower level XAA function which renders these clipped glyphs using
+   the basic color expansion functions exported by the chipset driver.
+   The NonTEGlyphRenderer itself may optionally be driver supplied to
+   facilitate work-arounds/optimizations at a higher level than usual.

+/********************************************************************
+
+   In this file we have GC level replacements for PolyText8/16,
+   ImageText8/16, ImageGlyphBlt and PolyGlyphBlt for TE (fixed) fonts.
+   The idea is that everything in this file is device independent.
+   The mentioned GCOps are merely wrappers for XAAGlyphBltTEColorExpansion
+   which calculates the boxes containing arbitrarily clipped text
+   and passes them to the TEGlyphRenderer which will usually be a lower 
+   level XAA function which renders these clipped glyphs using
+   the basic color expansion functions exported by the chipset driver.
+   The TEGlyphRenderer itself may optionally be driver supplied to
+   facilitate work-arounds/optimizations at a higher level than usual.
