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.
