   1 Random list of problems with i915g:
   2
   3 - Dies with BadDrawable on GLXFBconfig changes/destruction. Makes piglit totally
   4   unusable :( Upgrading xserver helped here, it doesn't crash anymore. Still
   5   broken, it doesn't update the viewport/get new buffers.
   6
   7 - Tends to hang the chip after a few minutes of openarena. Looks tiling related,
   8   at the last frame rendered has tiling corruption over the complete frame.
   9
  10 - Kills the chip in 3D_PRIMITIVE LINELIST with mesa-demos/fbotexture in
  11   wireframe mode.
  12
  13 - Tiling is funny: If unlucky, it renders/samples all black. No clue yet what's
  14   going on. Seems to depend on tiny details like whethever the sampler
  15   relocation is fenced/unfenced (broken _with_ fenced reloc using tiling bits!).
  16
  17 - Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason?
  18   Texture sampling from Y-tiled buffers seems to work, though (save above
  19   problems).
  20
  21 - Need to validate buffers before usage. Currently do_exec on the batchbuffer
  22   can fail with -ENOSPC.
