Description Timo Aaltonen 2009-01-13 11:20:14 UTC 
libdrm 2.4.1 worked fine, but when I tried 2.4.3 the xserver fails to start:

Xorg: ../../src/i830_batchbuffer.h:56: intel_batch_emit_dword: Assertion `pI830->batch_ptr != ((void *)0)' failed.

Comment 1 Wang Zhenyu 2009-01-13 17:36:12 UTC 
Could you test with xf86-video-intel 2.5.99.2?
Comment 2 Timo Aaltonen 2009-01-13 22:07:39 UTC 
I would, but it doesn't build using the drm headers from 2.6.28:

../doltcompile gcc -DHAVE_CONFIG_H -I. -I../../src -I..   -I/usr/include/xorg -I/usr/include/pixman-1    -I/usr/include/drm   -Wall -Wpointer-arith -Wstrict-prototypes 	-Wmissing-prototypes -Wmissing-declarations 	-Wnested-externs -fno-strict-aliasing -I/usr/include/xorg -I/usr/include/pixman-1   -I/usr/include/drm   -I/usr/include/X11/dri -I../../uxa -DI830_XV -DI830_USE_XAA -DI830_USE_EXA -Wall -g -O2 -MT i830_dri.lo -MD -MP -MF .deps/i830_dri.Tpo -c -o i830_dri.lo ../../src/i830_dri.c
../../src/i830_dri.c: In function 'I830DRISwapContext':
../../src/i830_dri.c:1168: error: 'drm_i915_flip_t' undeclared (first use in this function)
../../src/i830_dri.c:1168: error: (Each undeclared identifier is reported only once
../../src/i830_dri.c:1168: error: for each function it appears in.)
../../src/i830_dri.c:1168: error: expected ';' before 'flip'
../../src/i830_dri.c:1174: error: 'flip' undeclared (first use in this function)
make[5]: *** [i830_dri.lo] Error 1

what commits am I missing from the kernel?
Comment 3 Timo Aaltonen 2009-01-14 04:56:32 UTC 
I had to copy drm.h, drm_mode.h and i915_drv.h from libdrm 2.4.3 to make it compile, and it doesn't crash with 2.5.99.2.

The build failure needs to be sorted though, some compat stuff is clearly missing, also from 2.6.29 it seems.
Comment 4 Wang Zhenyu 2009-01-14 18:32:43 UTC 
yeah, that should be fixed. Please open another one, hope Jesse could sort out.
