Until we know how hw converts quads to polygon in beginning of
3D pipeline, for now unconditionally use last vertex convention.
Fix glean/clipFlat case.
|
|
Remove incorrect headless comment for gen6 fb write message.
Note current SIMD16 mode has already done right for control message.
|
|
Triangle fan provoking vertex for first convention should be
'vertex 1' in sandybridge clip state.
Partly fix glean/clipFlat case
|
|
Bug #32207. Fixes ARB_texture_rg/fbo-clear-formats (see my
fbo-clear-formats piglit branch currently)
|
|
Fixes a potential segfault on a non-native depthbuffer, and possible
accidental swrast fallback on extra color buffers.
|
|
Reported on irc by adamk.
|
|
Fixes a regression in ember since switching to the native FS backend,
and the new piglit tests glsl-fs-vec4-indexing-{2,3} for catching this.
|
|
Fixes 26 piglit cases on my GM965.
|
|
|
|
Clear target query buffer fixed occlusion query on sandybridge.

This reverts commit de6fd527a545f8344e074312544517d05573fb72.
Revert this workaround as it seems the real trouble is caused by
lineloop, which doesn't require GS convert on sandybridge actually.
|
|
Hopefully should fix bug #32520.
|
|
LINELOOP is converted to LINESTRIP at the beginning of the 3D pipeline.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=32596

Gen4 and Gen5 hardware can have a maximum supported nesting depth of 16.
Previously, shaders with control flow nested 17 levels deep would
cause a driver assertion or segmentation fault.
Gen6 (Sandybridge) hardware no longer has this restriction.
Fixes fd.o bug #31967.

This is the hack for input interactivity of frontbuffer rendering
(like we do for backbuffer at intelDRI2Flush()) by waiting for the n-2
frame to complete before starting a new one. However, for an
application doing multiple contexts or regular rebinding of a single
context, this would end up lockstepping the CPU to the GPU because
every unbind was considered the end of a frame.
Improves WOW performance on my Ironlake by 48.8% (+/- 2.3%, n=5)

All operands must be 16-bytes aligned in aligh16 mode. This fixes l_xxx.c
in oglconform.
|
|
This fixes
brw_eu_emit.c:179: validate_reg: Assertion `width == 1' failed.

Just like everywhere else, I never trust my constant uploads to
correctly put constants in the right places, even though that's so
rarely where the issue is.
|
|
It's mostly like gen4 message descriptor setup, except that the sizes
of type/control changed to be like gen5. Fixes 21 piglit cases on
gm45, including the regressions in bug #32311 from increased VS
constant buffer usage.
|
|
This makes conformance tests stable on sandybridge D0 to track
multisample state before SF/WM state.
|
|
Old MI_FLUSH command is deprecated on sandybridge blt.
|
|
Determine header present for fb write by msg length is not right
for SIMD16 dispatch, and if there're more output attributes, header
present is not easy to tell from msg length. This explicitly adds
new param for fb write to say header present or not.
Fixes many cases' hang and failure in GL conformance test.
|
|
The SNB alt-mode math does the denorm and inf reduction even for a
"raw MOV" like we do for g0 message header setup, where we are moving
values that aren't actually floats. Just use UD type, where raw MOVs
really are raw MOVs.
Fixes glxgears since c52adfc2e1d130effea940e75690897eb5d3ceaa, but no
piglit tests had regressed(!)

constants. For the 7.9 and 7.10 branches as well.
|
|
The only mismatch between the two is that we have to clear the
destination's alpha to 1.0. Fixes WOW performance on my Ironlake,
from a few frames a second to almost playable.
|
|
Before, we were going off of a couple of known (hopeful) matches
between internalFormats and the cpp of the read buffer. Instead, we
can now just look at the gl_format of the two to see if they match.
We should avoid bad blits that might have been possible before, but
also allow different internalFormats to work without having to
enumerate each one.
|
|
The blit that follows appears in the command stream so it's serialized
with previous rendering. Any queued vertices in the tnl layer were
already flushed up in mesa/main/.
|
|
Not fixing a particular bug, just noticed by code inspection.
|
|
This matches how we did the math instructions pre-gen6, though it
applies to non-math as well.
Fixes vp1-LIT test 2 (degenerate case: 0 ^ 0 -> 1)
|

The program should be disassembled after it's uploaded
|

|
This is still awful, but my ability to care about reworking the old
backend so we can just get a temporary value into a POW is awfully low
since the new backend does this all sensibly.
Fixes:
fp1-LIT test 1
fp1-LIT test 3 (case x < 0)
fp1-POW test (exponentiation)
fp-lit-mask
|
|
Fixes glsl-bug-22603.
|

Fixes fp-arb-fragment-coord-conventions-none
|
|
RNDD isn't one of the instructions that can do conversion from
execution type to destination type.
Fixes glsl-vs-arrays-3.
|
|
This requires shuffling the driconf XML macros around, since they use
true and false tokens expecting them to not get expanded to anything.
|
|
If a source operand has a non-native swizzle (e.g. the KIL instruction
cannot have a swizzle other than .xyzw), the lowering pass uses one or more
MOV instructions to move the operand to an intermediate temporary with
native swizzles.
This commit fixes that the presubtract information was lost during
the lowering.
NOTE: This is a candidate for both the 7.9 and 7.10 branches.

|
This fixes broken rendering of trees in ETQW. The trees still disappear
for an unknown reason when they are close.
Broken since:
2ff9d4474bdf5f05852ad4963d0b597d20743678
r300/compiler: make lowering passes possibly use up to two less temps
NOTE: This is a candidate for the 7.10 branch.
|
|
There are exceptions to the table for depth texturing or rendering to
not-quite-supported formats thanks to the non-orthogonal component
selection for surface formats, but it's still a lot simpler.
|
|
One less place to forget to put your new MESA_FORMAT support in.
|
|
|
|
This starts spantmp2.h down the path of using MESA_FORMAT_* for
specifying the format instead of the crazy GL format/type combo.
|
|
assert(current_save_state < MAX_META_OPS_DEPTH) did not compile.
Rename current_save_state to SaveStackDepth to be more consistent with
the style of the other fields.
|
|
VS places color attributes together so that SF unit can fetch the right
attribute according to object orientation. This fixes light issue in
mesa demo geartrain, projtex.
|
|
_mesa_meta_CopyPixels results in nested meta operations on Sandybridge.
Previoulsy the second meta operation overrides all states saved by the
first meta function.
