aco/gfx10: Wait for pending SMEM stores before loads

Currently if you have an SMEM store followed by an SMEM load that
loads the same location as was written, it won't work because the
store isn't finished before the load is executed. This is NOT
mitigated by an s_nop instruction on GFX10.

Since we currently don't have proper alias analysis, this commit adds
a workaround which will insert an s_waitcnt lgkmcnt(0) before each
SSBO load if they follow a store. We should further refine this in
the future when we can make sure to only add the wait when we load the
same thing as has been stored.

5 years agopanfrost: Fix the DISCARD_WHOLE_RES case in transfer_map()

panfrost: Fix the DISCARD_WHOLE_RES case in transfer_map()

The current implementation does not synchronize on BO readiness when
DISCARD_WHOLE_RES flag is set, which can lead to misbehaviours when the

freedreno/ir3: Add a NIR pass to select tex instructions eligible for pre-fetch

The pass should run once at the end of shader compilation, for a4xx
onwards. It iterates texture sampling instructions and mark those
eligibile for pre-dispatch by changing the tex op from 'tex' to
'tex_prefetch'. An instruction is eligibile if:

* The coordinate is a vector where all its components come from a
  shader input.
* The order of the components match exactly that of the input (no
  swizzles).
* The instruction is in the 'main' function, and in the outer
  most-block.

The first two restrictions were arrived to empirically, so more
testing could tighten or loosen it.

The 3rd restriction is there to allow moving the instructions
eligible for pre-dispatch to the beginning of the shader, so
that we don't block the registers holding the result for too
long.
