Bugzilla – Bug 5115
Drivers for ATI cards segfault with no on-card memory reserved for textures
Last modified: 2009-08-24 12:23:36 UTC
There seems to be a (somewhat reasonable) assumption in the common DRI texture
management code that heap 0 is always valid. However, the DDX drivers for ATI
cards can end up reserving no on-card memory for textures under some
circumstances, in which case heap 0 will end up being invalid, resulting in a
segfault. I'll attach a patch which avoids the segfault by setting up heap 0 for
the GART texture area in that case.

Fixed in Mesa CVS trunk and 6.4 branch.
