The primary consumer of this (miptree relayout) already has this code
for handling failure, and the other paths want to know if failure
actually occurs and do something appropriate, which may not include
memcpy.
|
|
If a non-zero src_y was used, this would break piglit
depth-level-clamp.

Bug #26966: 945 miptree pitch disagreement with libdrm.
|
|
We don't have any fallback code here, and we want to avoid this path
if failure would happen, so just assert.
|
|
This is the last pitch-dependent part of miptree setup.

MOV, MOV."
This reverts commit 46450c1f3f93bf4dc96696fc7e0f0eb808d9c08a. I was
wrong about null reg behavior -- it reads undefined, not 0. And
they're not kidding.

Corresponds to d225a25e21a24508aea3b877c78beb35502e942d and fixes
piglit glsl-fs-loop-nested. Bug #25173.

We were doing it ad-hoc before, as instructions with potential
aliasing problems were identified. But thanks to swizzling basically
anything can have aliasing, so just do it generally at source reg
setup time. This is somewhat inefficient, because sometimes an
operation doesn't need unaliasing protection if the swizzling is safe,
but the unaliasing before didn't cover those cases either.
Fixes piglit glsl-fs-loop.

We were patching up all the break and continues between the start of
our loop and the end of our loop, even if they were breaks/continues
for an inner loop. Avoiding patching already patched breaks/continues
fixes piglit glsl-vs-loop-nested.

The code was walking over the regs of pairs of attributes and checking
whether the attribute with a given reg index had point sprite enabled.
So the point sprite setup code was rarely even getting executed.
Instead, we need to determine which channels of a reg need point
sprite coordinate replacement. In addition, it was multiplying the
attribute by 1/w, when it's supposed to cover (0, 1) in each direction
regardless of w, and it wasn't filling in the Z and W components of
the texcoord as specified.
Fixes piglit point-sprite and the spriteblast demo. Bug #24431, #22245.

This would be triggered by use of sqrt() along with control flow.

The bad response length would hang the GPU with a masked sample in a
shader using control flow. For 8-wide, the response length is always
4, and masked slots are just not written to. brw_wm_glsl.c already
allocates registers in the right locations.
Fixes piglit glsl-fs-bug25902 (fd.o bug #25902).

If flush happens inside radeonRefillCurrentMaRegion the last dma buffer would
be unmapped twice. Unmapping buffer when moving buffer to wait list fixes the
mapping error.

swizzle in the pixel shader

Reemitting dirty states on flush causes problems if the GL context
isn't fully consistent when we get to it. It didn't serve any specific
purpose, so, use nouveau_bo_state_emit instead.

Saves an instruction in PINTERP, LINTERP, and PIXEL_W from
brw_wm_glsl.c For non-GLSL it isn't used yet because the deltas have
to be laid out differently.
