i915g: TODO about point sprites
[mesa.git] / src / gallium / drivers / i915 / TODO
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 - Add support for PIPE_CAP_POINT_SPRITE either via the draw module or directly
7 via the hardware, look at the classic driver, more advanced.
8
9 - Dies with BadDrawable on GLXFBconfig changes/destruction. Makes piglit totally
10 unusable :( Upgrading xserver helped here, it doesn't crash anymore. Still
11 broken, it doesn't update the viewport/get new buffers.
12
13 - Tends to hang the chip after a few minutes of openarena. Looks tiling related,
14 at the last frame rendered has tiling corruption over the complete frame.
15
16 - Kills the chip in 3D_PRIMITIVE LINELIST with mesa-demos/fbotexture in
17 wireframe mode.
18
19 - Tiling is funny: If unlucky, it renders/samples all black. No clue yet what's
20 going on. Seems to depend on tiny details like whethever the sampler
21 relocation is fenced/unfenced (broken _with_ fenced reloc using tiling bits!).
22
23 - Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason?
24 Texture sampling from Y-tiled buffers seems to work, though (save above
25 problems).
26
27 - Need to validate buffers before usage. Currently do_exec on the batchbuffer
28 can fail with -ENOSPC.
