[Mesa-dev] [PATCH 0/7] radv: implement 32-bit GPU pointers for user SGPRs

[Samuel Pitoiset]

Hi list,

This series implements support for 32-bit GPU pointers which reduces
the number of user SGPRs that are needed for binding descriptors.

There is no CTS regressions and all games seem to get a minor
performance boost (tested on Polaris/Vega).

If you want to test or run some benchmarks yourself, please note
that LLVM 7.0 is required.

Please review,
Thanks!

Samuel Pitoiset (7):
  radv/winsys: request high address
  radv/winsys: allow to allocate BOs in the 32-bit addr space
  radv: set amdgpu-32bit-address-high-bits LLVM attribute
  radv: allocate the upload BO in the 32-bit addr space
  radv: allocate descriptor BOs in the 32-bit addr space
  radv: add set_loc_shader_ptr() helper
  radv: add support for 32-bit pointers in user data SGPRs
