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 + +* **Add support for compute interface** + * _Difficulty:_ Medium + * _Who's working on it:_ + * _Date Started: _ + * _Status:_ WIP - Initial patch for non-compiler parts is [[here|http://people.freedesktop.org/~tstellar/0001-radeonsi-WIP-compute-patch.patch]] + * _Description:_ + * Add support for emitting dispatch packets and related compute state +* **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 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|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. +* **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.
