[Mesa-dev] [PATCH 0/7] Use byte offsets for ubo pulls

[Jason Ekstrand]

This little patch series converts both backends to use byte offsets for UBO
pulls.  This has the advantage of allowing us to just use a stried of 1 on
the surface in both cases and unifies surface state across backends.
Unfortunately, this does not unify it with SSBOs because they use
SURFACEFORMAT_RAW and, according to Curro, untyped image load/store
instructions get grumpy if they're not on a RAW surface.

Jason Ekstrand (7):
  i965/vec4: Use byte offsets for UBO pulls on Sandy Bridge
  i965/fs: Use a stride of 1 and byte offsets for UBOs
  i965/vec4: Use a stride of 1 and byte offsets for UBOs
  i965/nir: Remove unused indirect handling
  i965/nir: Add a nir_lower_uniforms helper
  i965/fs: Make uniform offsets be in terms of bytes
  i965/vec4: Make uniform offsets be in terms of bytes
