[Mesa-dev] [PATCH v3 00/14] radeonsi: offchip tessellation

[Bas Nieuwenhuizen]

Addressed review comments by Marek.

As part of that the max number of patches per threadgroup was reduced to 40
from 64. This reduced unigine-heaven performance from 43.1 fps to 42.5 fps
(the number varies a little but the magnitude of the difference is pretty constant)

However it is likely that the optimal value for it differs between applications,
and I don't have that many applications to check against.

Any thoughts on the issue?

Bas Nieuwenhuizen (14):
  radeonsi: Add buffer for offchip storage between TCS and TES.
  radeonsi: Add offchip tessellation parameters.
  radeonsi: Define build_tbuffer_store_dwords earlier to support new
    users.
  radeonsi: Add buffer load functions.
  radeonsi: Use correct parameter index for LS_OUT_LAYOUT.
  radeonsi: Add user SGPR for the layout of the offchip buffer.
  radeonsi: Add offchip buffer address calculation.
  radeonsi: Store inputs to memory when not using a TCS.
  radeonsi: Use buffer loads and stores for passing data from TCS to
    TES.
  radeonsi: Remove LDS layout user SGPR's from TES.
  radeonsi: Enable dynamic HS.
  radeonsi: Add barrier before writing the tess factors.
  radeonsi: Process multiple patches per threadgroup.
  radeonsi: Allow TES distribution between shader engines.
