i915g: Disable LIS7 state updates for now
[mesa.git] / src / gallium / drivers / i915 / TODO
1 Random list of problems with i915g:
2
3 - Check if PIPE_CAP_BLEND_EQUATION_SEPARATE work, the code is there.
4 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 - What does this button do? Figure out LIS7 with regards to depth offset.
10
11 - Dies with BadDrawable on GLXFBconfig changes/destruction. Makes piglit totally
12 unusable :( Upgrading xserver helped here, it doesn't crash anymore. Still
13 broken, it doesn't update the viewport/get new buffers.
14
15 - Tends to hang the chip after a few minutes of openarena. Looks tiling related,
16 at the last frame rendered has tiling corruption over the complete frame.
17
18 - Kills the chip in 3D_PRIMITIVE LINELIST with mesa-demos/fbotexture in
19 wireframe mode.
20
21 - Tiling is funny: If unlucky, it renders/samples all black. No clue yet what's
22 going on. Seems to depend on tiny details like whethever the sampler
23 relocation is fenced/unfenced (broken _with_ fenced reloc using tiling bits!).
24
25 - Y-tiling is even more fun. i915c doesn't use it, maybe there's a reason?
26 Texture sampling from Y-tiled buffers seems to work, though (save above
27 problems).
28
29 - Need to validate buffers before usage. Currently do_exec on the batchbuffer
30 can fail with -ENOSPC.
