Radeonsi To Do list

And here is the radeonsi to do list; if you feel something is missing please add it. If you have done something and it no longer needs to be investigated, happily erase it from here :).

LLVM

• Turn on basic block vectorizer pass
  • Difficulty: Medium
  • Who's working on it:
  • Status: N/A
  • Description:
  • We might be able to use this pass to merge single dwords loads from constant memory into multiple dword loads.

Compute

• Use asynchronous compute rings for compute
  • Difficulty: Medium
  • Who's working on it: N/A
  • Date Started: N/A
  • Status: N/A
  • Description:
  • SI supports two asynchronous compute rings. Use them for compute to avoid contention with gfx on the main gfx ring.

3D Features

• TGSI opcodes DDX/DDY
  • Difficulty: Medium
  • Who's working on it: Michel Dänzer
  • Status: WIP
  • Note:
• MSAA support on SI
  • Difficulty: Medium
  • Who's working on it:
  • Status: N/A
  • Note: Works very similarly to cayman. Code from r600g can be ported over.
• MSAA with colorbuffer compression on SI
  • Difficulty: Medium
  • Who's working on it:
  • Status: N/A
  • Note: Works very similarly to cayman. Code from r600g can be ported over.
• Fast color clear for MSAA buffers on SI
  • Difficulty: Medium
  • Who's working on it: N/A
  • Note: Works very similarly to cayman. Code from r600g can be ported over.
• MSAA on the window system framebuffer
  • Difficulty: Medium
  • Who's working on it: N/A
  • Note: AFAIK, nothing has been done for it in st/dri. I think we should allocate private MSAA color/depth/stencil surfaces in Gallium and ask the DDX to only allocate the single-sampled front where we will resolve the MSAA colorbuffer on ?SwapBuffers.
• transform feedback support
  • Difficulty: Medium
  • Who's working on it: N/A
  • Note: Works very similarly to cayman. Code from r600g can be ported over.
• timer query support
  • Difficulty: Easy
  • Who's working on it: N/A
  • Note: Works very similarly to r6xx-cayman. Code from r600g can be ported over.
• Polygon stippling
  • Difficulty: Easy
  • Who's working on it: N/A
  • Note: Take advantage of util/u_pstipple. It contains the shader transformation code and can create a stipple texture.
• Polygon/line/point smoothing
  • Difficulty: Medium
  • Who's working on it: N/A
• Texture buffer objects (read-only buffer resources in shaders)
  • Difficulty: Medium
  • Who's working on it: N/A
  • Note:: Core Mesa/Gallium support might need some work too.
• Uniform buffer objects (constant buffers)
  • Difficulty: Medium
  • Who's working on it: N/A
  • Note:: Core Mesa/Gallium support might need some work too.
• HyperZ support
  • Difficulty: Hard
  • Who's working on it: N/A
  • Note:: Works very similarly to cayman. Code for r600g can be ported over.
• Geometry shaders
  • Difficulty: Medium
  • Who's working on it: N/A
  • Note:: Core Mesa/Gallium support might need some work too.
