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).

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.
