i915g: update TODO
Comments about the deleted stuff: - openaren hang: likely caused by the vertex corruptions, fixed by Jakob. - tiling: Y-tiling works with my hw-clear branch. X-tiling works as merged to master a while ago (execbuf2 version). Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

unusable :( Upgrading xserver helped here, it doesn't crash anymore. Still
broken, it doesn't update the viewport/get new buffers.
-- Tends to hang the chip after a few minutes of openarena. Looks tiling related,
- at the last frame rendered has tiling corruption over the complete frame.
-
- Kills the chip in 3D_PRIMITIVE LINELIST with mesa-demos/fbotexture in
- wireframe mode.
-
-- Tiling is funny: If unlucky, it renders/samples all black. No clue yet what's
- going on. Seems to depend on tiny details like whethever the sampler
- relocation is fenced/unfenced (broken _with_ fenced reloc using tiling bits!).
+ wireframe mode. Changing the cullmode to cw from none mitigates the crash. As
+ does emitting only one line segment (2 indices) per 3D_PRIMITIVE command in
+ the batch.
- Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason?
Texture sampling from Y-tiled buffers seems to work, though (save above
problems).
+ RESOLVED: Y-tiling works with the render engine, but not with the blitter.
+ Use u_blitter and hw clears (PRIM3D_CLEAR_RECT).
-- Need to validate buffers before usage. Currently do_exec on the batchbuffer
- can fail with -ENOSPC.
+- src/xvmc/i915_structs.h in xf86-video-intel has a few more bits of various
+ commands defined. Scavenge them and see what's useful.
