This showed up as cairo-gl gradients being inverted on everyone but
Intel, where I'd apparently tweaked the transformation to work around
the bug. Fixes piglit fbo-fragcoord.

IF statements were getting flattened while they were broken. With
Zhenyu's last fix for ENDIF's type, everything appears to have lined
up to actually work.
This regresses two tests:
glsl1-! (not) operator (1, fail)
glsl1-! (not) operator (1, pass)
but fixes tests that couldn't work before because the IFs couldn't be
flattened:
glsl-fs-discard-01
occlusion-query-discard
(and, naturally, this should be a performance improvement for apps
that actually use IF statements to avoid executing a bunch of code).

Sometimes we swizzled in a different channel it looked like, and
sometimes we swizzled in zero. Or something.
Having looked at the output of another code generator for this chip,
this is approximately what they do, too: use align1 math on
temporaries, and then move the results into place.

glean/vp1-EXP test
glean/vp1-LG2 test

DD_POINT_SIZE got never set for some time now (as it was set only in ifdefed
out code), which caused the r200 driver to use the point primitive mistakenly
in some cases which can only do size 1 instead of point sprite. Since the
logic to use point instead of point sprite prim is flaky at best anyway (can't
work correctly for per-vertex point size), just drop this and always emit point
sprites (except for AA points) - reasons why the driver tried to use points for
size 1.0 are unknown though it is possible they are faster or more conformant.
Note that we can't emit point sprites without point sprite cntl as that might
result in undefined point sizes, hence need drm version check (which was
unnecessary before as it should always have selected points). An
alternative would be to rely on the RE point size clamp controls which could
clamp the size to 1.0 min/max even if the SE point size is undefined, but currently
always use 0 for min clamp. (As a side note, this also means the driver does
not honor the gl spec which mandates points, but not point sprites, with zero size
to be rendered as size 1.)
This should fix recent reports of https://bugs.freedesktop.org/show_bug.cgi?id=702.
This is a candidate for the mesa 7.9 branch.

This reverts commit 9c39a9fcb2c76897e9b5aff68ce197a411c4e25c.
Remove VS SPF mode, conditional instruction works for VS now.

That should also be immediate value for type W.

Fixes 10 piglit cases that were assertion failing.
|
|
Fixes assertion failure with texture swizzling in the GLSL path when
it's triggered (such as gen6 FF or ARB_fp shadow comparisons).
Fixes:
texdepth
texSwizzle
fp1-DST test
fp1-LIT test 3

Also fixup code comment to reflect that the GPU requires DWORD
alignment, but in this case does not actually pass the value "in
DWORDs" as I previously stated.
|
|
This reverts commit 76360d6abc9e0195bc5c373101ae616e68b2e6e6. On
second thought, it turned out that sync objects also used the
wait_rendering API like this, and would need the same treatment, and
so wait_rendering itself is fixed in libdrm now.
|
|
We were asking for a wait to GTT read (all GPU rendering to it
complete), instead of asking for all GPU reading from it to be
complete. Prevents swapbuffers-based apps from running away with
rendering, and produces a better input experience.

agd5f: add support to radeon/r200/r300 as well
|
|
|
|
|
|
A call to radeon_prepare_render() at the beginning of draw
operations was placed too deep in the call chain,
inside r300RunRenderPrimitive(), instead of
r300DrawPrims() where it belongs. This leads to
emission of stale target color renderbuffer into the cs if
bufferswaps via page-flipping are used, and thereby causes
massive rendering corruption due to unsynchronized
rendering into the active frontbuffer.
This patch fixes such problems for use with the
upcoming radeon page-flipping patches.

The width of the 2D blits used to copy the data is defined as a 16-bit
signed integer, but the pitch must be DWORD aligned. Limit to an integral
number of DWORDs, (1 << 15 - 4) rather than (1 << 15 -1).
Fixes corruption to data uploaded with glBufferSubData.

intel_finalize_mipmap_tree() does this optimization too, just more
aggressively.
|
|
logbase2(max(width, height, depth)) ==
max(logbase2(width), logbase2(height), logbase2(depth)), but in 60
bytes less code.

In testing on Ironlake, the histogram of clocks/pixel results for the
system memcpy and magic unaligned memcpy show no noticeable difference
(and no statistically significant difference with the 5510 samples
taken, though the stddev is large due to what looks like the cache
effects from the different texture sizes used).
|
|
This provides the optimizer with hints about code hotness, which we're
quite certain about for debug printouts (or, rather, while we
developers often hit the checks for debug printouts, we don't care
about performance while doing so).
|
|
|
|
No measurable performance difference on cairo-perf-trace, but
simplifies the code and should have cache benefit in general.
