7 years agofreedreno: a bit of query refactor

freedreno: a bit of query refactor

Move a bit more of the logic shared by all query types (active tracking,

for a5xx.

For a5xx (and actually some queries on a4xx) we can accumulate results
in the cmdstream, so we don't need this elaborate mechanism of tracking

7 years agoi965/vec4: Avoid reswizzling MACH instructions in opt_register_coalesce().
Kenneth Graunke [Fri, 21 Apr 2017 08:28:13 +0000 (01:28 -0700)]
i965/vec4: Avoid reswizzling MACH instructions in opt_register_coalesce().

opt_register_coalesce() was optimizing sequences such as:

   mul(8) acc0:D, attr18.xyyy:D, attr19.xyyy:D
   mach(8) vgrf5.xy:D, attr18.xyyy:D, attr19.xyyy:D
   mov(8) m4.zw:F, vgrf5.xxxy:F

into:

   mul(8) acc0:D, attr18.xyyy:D, attr19.xyyy:D
   mach(8) m4.zw:D, attr18.xxxy:D, attr19.xxxy:D

This doesn't work - if we're going to reswizzle MACH, we'd need to
reswizzle the MUL as well.  Here, the MUL fills the accumulator's .zw
components with attr18.yy * attr19.yy.  But the MACH instruction expects
.z to contain attr18.x * attr19.x.  Bogus results ensue.

No change in shader-db on Haswell.  Prevents regressions in Timothy's
patches to use enhanced layouts for varying packing (which rearrange
code just enough to trigger this pre-existing bug, but were fine
themselves).

7 years agoradv: start allocating user sgprs

radv: start allocating user sgprs

This adds an initial implementation to allocate the user
sgprs and make sure we don't run out if we try to bind
a bunch of descriptor sets.

This can be enhanced further in the future if we add
support for inlining push constants.
