The _ColorDrawBuffers is a piece of computed state that gets for the
current draw/read buffers at _mesa_update_state time. However, this
function actually gets used for non-current draw/read buffers when
checking if an FBO is complete from the driver's perspective. So,
instead of trying to just look at the attachment points that are
currently referenced by glDrawBuffers, look at all attachment points
to see if they're driver-supported formats. This appears to actually
be more in line with the intent of the spec, too.
Fixes a segfault in my upcoming fbo-clear-formats piglit test, and
hopefully bug #30278
(cherry picked from commit 0ea49380e2)
This starts spantmp2.h down the path of using MESA_FORMAT_* for
specifying the format instead of the crazy GL format/type combo.
(cherry picked from commit 28bab24e16)
Fixes a potential segfault on a non-native depthbuffer, and possible
accidental swrast fallback on extra color buffers.
(cherry picked from commit 94ed481131)
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)

Triangle fan provoking vertex for first convention should be
'vertex 1' in sandybridge clip state.
Partly fix glean/clipFlat case
(cherry picked from commit 9977297ad9)
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.
(cherry picked from commit bea6539abf)
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.
(cherry picked from commit df4d83dca4)
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
(cherry picked from commit d88aa6fe3e)
rc_inst_can_use_presub() wasn't checking for too many RGB sources in
Alpha instructions or too many Alpha sources in RGB instructions.
(cherry picked from commit e96e86d07b)
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.
(cherry picked from commit 634a7dce9c)
This adds a new optional max_depth parameter (defaulting to 0) to
lower_if_to_cond_assign, and makes the pass only flatten if-statements
nested deeper than that.
By default, all if-statements will be flattened, just like before.
This patch also renames do_if_to_cond_assign to lower_if_to_cond_assign,
to match the new naming conventions.
(cherry picked from commit 9ac6a9b2fa)
These mistakenly computed 't' instead of t * t * (3.0 - 2.0 * t).
Also, properly vectorize the smoothstep(float, float, vec) variants.
NOTE: This is a candidate for the 7.9 and 7.10 branches.
(cherry picked from commit d7423a6531)
This is the same as what the array dereference handler does.
Fixes piglit test glsl-link-struct-array (bugzilla #31648).
NOTE: This is a candidate for the 7.9 and 7.10 branches.
(cherry picked from commit 2d577ee730)
do_assignment may apply implicit conversions to coerce the base type
of initializer to the base type of the variable being declared. Fixes
piglit test glsl-implicit-conversion-02 (bugzilla #32287). This
probably also fixes bugzilla #32273.
NOTE: This is a candidate for the 7.9 branch and the 7.10 branch.
(cherry picked from commit d7f27e2e76)
The hardware supports zero stride just fine. This is a port
of 2af8a19831 from r300g.
NOTE: This is a candidate for both the 7.9 and 7.10 branches.

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)
(cherry picked from commit c52adfc2e1)
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.
(cherry picked from commit 4374703a9b)
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 c52adfc2e1, but no
piglit tests had regressed(!)
(cherry picked from commit 4fe78d3e12)
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.
(cherry picked from commit 290a1141bc)
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.
(cherry picked from commit ec03b316b4)
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/.
(cherry picked from commit e65c643792)
RNDD isn't one of the instructions that can do conversion from
execution type to destination type.
Fixes glsl-vs-arrays-3.
(cherry picked from commit 7cec7bf56c)
This requires shuffling the driconf XML macros around, since they use
true and false tokens expecting them to not get expanded to anything.
