   1 Random list of problems with i915g:
   2
   3 - Check if PIPE_CAP_BLEND_EQUATION_SEPARATE and PIPE_CAP_TEXTURE_MIRROR_REPEAT
   4   work, the code is there. If not fix it! A simple task, good for beginners.
   5
   6 - Dies with BadDrawable on GLXFBconfig changes/destruction. Makes piglit totally
   7   unusable :( Upgrading xserver helped here, it doesn't crash anymore. Still
   8   broken, it doesn't update the viewport/get new buffers.
   9
  10 - Tends to hang the chip after a few minutes of openarena. Looks tiling related,
  11   at the last frame rendered has tiling corruption over the complete frame.
  12
  13 - Kills the chip in 3D_PRIMITIVE LINELIST with mesa-demos/fbotexture in
  14   wireframe mode.
  15
  16 - Tiling is funny: If unlucky, it renders/samples all black. No clue yet what's
  17   going on. Seems to depend on tiny details like whethever the sampler
  18   relocation is fenced/unfenced (broken _with_ fenced reloc using tiling bits!).
  19
  20 - Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason?
  21   Texture sampling from Y-tiled buffers seems to work, though (save above
  22   problems).
  23
  24 - Need to validate buffers before usage. Currently do_exec on the batchbuffer
  25   can fail with -ENOSPC.
