The i915 (and related graphics cores) only support TEXCOORDMODE_CLAMP and
TEXCOORDMODE_CUBE when using cube map texture coordinates, so fall back to
software rendering for other modes to avoid potential gpu hang issue. This
fixes scorched3d issue on 945GM(see bug 14539).
SSE movss from memory zeroes out everything above the destination dword, so
we get the (a, 0) or (a, 0, 0) result that these functions needed.
Bug #16520.
The ctx->Driver.GenerateMipmap() hook only expects cubemap face enums, not
CUBE_MAP_ARB, so walk all faces when we encounter that. Fixes oglconform
fbo.c segfault with both swrast and i965 drivers.
The images aren't mapped at this point, so we want the generic Mesa path for
GenerateMipmapEXT that does the mapping/unmapping for us. Ideally Mesa would
just call it for us.
This is fallout from the ffvertex_prog.c work. It doesn't call
ProgramStringNotify, so we don't set param_state, so we wouldn't track when
VP parameters changed, and constants wouldn't get uploaded. Instead, remove
param_state entirely and just use the real value that we want to be tracking.
Fixes rendering in openarena since BRW_NEW_BATCH got disentangled from
BRW_NEW_INDICES.
Bug #18822.
Intel docs state that only 830/845 have VBOs, 855/865 don't. So
lets just not use them on i8xx at all.
This restores the old pre-vbo code and uses it on all 8xx hw.
The CACHE_NEW_SURFACE bit always gets spammed since we get many different
surface BOs per state emit, but the only consumer of it wanted to just know
how many surfaces were enabled.
Later primitives, even if they caused a full state validate, wouldn't check
that there was enough space in the batchbuffer, occasionally triggering the
sanity check. We also skipped the aperture space check, even if it would
mean bringing in new programs and associated state.
This uses a GLX VendorPrivate request. VendorPrivates are real GLX API
calls but use the same protocol request. XCB does not currently
support specific VendorPrivetes directly. See eg.:

for more information.
