Swizzling needs the destination surface in VRAM, but the subsequent
rendering operations making use of it are likely to not care. Fire the
ring after validation to leave the memory manager more room for
maneuvering.

nouveau reallocated the mipmap tree on every MIN_FILTER call to account
for mipmap change. We only need to do this if the texture does not fit
in the existing mipmap tree. This gives a big performance boost for a
game like bzflag which changes MIN_FILTER all the time for its font
rendering.

The default viewport is the window rectangle, which is set up by
_mesa_make_current(). To be able to do that we need to get the
window dimension (and buffers) first, so we have to call
intel_prepare_render() before we can call into _mesa_make_current().
Fixes #26676 and #26678.

The pitch is not really an inherent part of the miptree, since it's
not part of any of the layout calculations, and it's dictated by the
libdrm-allocated region pitch now.
|
|
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.

|
|
|
|
This lets us avoid conditionals and duplicated code in several places.

Use the _mesa_clip_readpixels() function to clip the src region against
the buffer's bounds. Neatly, the resulting pixel unpack object's
SkipPixels/SkipRows fields can be used to determine the position of the
region in the destination texture.
Fixes crash in progs/samples/copy.c and probably other cases.

And replace some instances of GLuint with unsigned int to avoid pulling in
GL/gl.h

|
Nearly certain this is what was intended; it compiles, but I'm not sure
this path is ever hit in my tests.

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

Found while debugging bug #24119.

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).

From 247e121106e8d3e389f2e5a6edf13ea70ac18df7 Mon Sep 17 00:00:00 2001
These seem to be documented in
<http://www.svgopen.org/2003/papers/RasterOperationsUsingFilterElements/index.html>.

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.
|
|
changes arguments of util_blit_pixels_tex and util_gen_mipmap to
struct pipe_sampler_view * instead of struct pipe_texture *.

This branch already seems to have the nv50_tex.c fix.
