Software:
Fedora Core 2
Kernel 2.6.8 with DRM from CVS 2004-10-02
Xorg 6.7.0 with latest unichrome driver releases
Hardware:
Via MEII6000 mainboard with onboard CLE266 Rev. 17
I'm not convinced I'm building DRM properly. The procedure I'm using
to update drm in the FC2 kernel tree is:
1) cd linux
sh ../scripts/create_linux_pci_lists.sh < ../shared/drm_pciids.txt
2) scripts/create_lk_drm.sh <kernel dir> 2.6
3) cp linux-2.6/*.[ch] <kernel dir>/drivers/char/drm/
4) cp linux-2.6/Makefile.kernel <kernel dir>/drivers/char/drm/Makefile
Step (1) is needed because (2) fails to build drm_pciids.h. Steps (3) &
(4) are needed to stop compilation from failing due to a missing
radeon_i2c.h.
I also have to apply the following patch:
diff -Naur linux-2.6.8/drivers/char/drm/drm_compat.h
linux-2.6.8.new/drivers/char/drm/drm_compat.h
--- linux-2.6.8/drivers/char/drm/drm_compat.h 2004-10-03 00:34:58.999379040 +0100
+++ linux-2.6.8.new/drivers/char/drm/drm_compat.h 2004-10-03 00:54:29.875378832
