2011-01-04i965: Add support for SRGB DXT1 formats.Eric Anholt
This makes fbo-generatemipmap-formats GL_EXT_texture_sRGB-s3tc match fbo-generatemipmap-formats GL_EXT_texture_compression_s3tc and swrast in bad DXT1_RGBA alpha=0 handling, but it means we won't unpack and repack someone's textures into uncompressed SARGB8 format.
2011-01-04intel: Merge our choosetexformat fallbacks into core.Eric Anholt
We now share the type/format -> MESA_FORMAT_* mappings with software mesa, and the core supports most of the fallbacks hardware drivers will want.
2011-01-04r300/compiler: disable the rename_regs pass for loopsMarek Olšák
This workaround fixes rendering of kwin thumbnails. NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-01-04r300/compiler: Fix black terrain in Civ4Tom Stellard
rc_inst_can_use_presub() wasn't checking for too many RGB sources in Alpha instructions or too many Alpha sources in RGB instructions. Note: This is a candidate for the 7.10 branch.
2011-01-04intel: When validating an FBO's combined depth/stencil, use the given FBO.Eric Anholt
We were looking at the current draw buffer instead to see whether the depth/stencil combination matched. So you'd get told your framebuffer was complete, until you bound it and went to draw and we decided that it was incomplete.
2011-01-04intel: Fix segfaults from trying to use _ColorDrawBuffers in FBO validation.Eric Anholt
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
2011-01-04osmesa: pass context to _mesa_update_framebuffer_visual()Brian Paul
Fixes http://bugs.freedesktop.org/show_bug.cgi?id=32814
2011-01-04i965: Use last vertex convention for quad provoking vertex on sandybridgeZhenyu Wang
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.
2011-01-04i965: Correct comment for gen6 fb write control message settingZhenyu Wang
Remove incorrect headless comment for gen6 fb write message. Note current SIMD16 mode has already done right for control message.
2011-01-04i965: Fix provoking vertex select in clip state for sandybridgeZhenyu Wang
Triangle fan provoking vertex for first convention should be 'vertex 1' in sandybridge clip state. Partly fix glean/clipFlat case
2011-01-03intel: Use tri clears when we don't know how to blit clear the format.Eric Anholt
Bug #32207. Fixes ARB_texture_rg/fbo-clear-formats (see my fbo-clear-formats piglit branch currently)
2011-01-03intel: Handle forced swrast clears before other clear bits.Eric Anholt
Fixes a potential segfault on a non-native depthbuffer, and possible accidental swrast fallback on extra color buffers.
2011-01-03radeon: fix build on non-KMS systems.Dave Airlie
Reported on irc by adamk.
2010-12-28i965: Do lowering of array indexing of a vector in the FS.Eric Anholt
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.
2010-12-28i965: Fix regression in FS comparisons on original gen4 due to gen6 changes.Eric Anholt
Fixes 26 piglit cases on my GM965.
2010-12-28i965: Factor out the ir comparision to BRW_CONDITIONAL_* code.Eric Anholt
2010-12-28i965: Fix occlusion query on sandybridgeZhenyu Wang
Clear target query buffer fixed occlusion query on sandybridge. https://bugs.freedesktop.org/show_bug.cgi?id=32167
2010-12-28Revert "i965: upload multisample state for fragment program change"Zhenyu Wang
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.
2010-12-27i965: Internally enable GL_NV_blend_square on ES2.Kenneth Graunke
Hopefully should fix bug #32520.
2010-12-27i965: don't spawn GS thread for LINELOOP on SandybridgeXiang, Haihao
LINELOOP is converted to LINESTRIP at the beginning of the 3D pipeline. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=32596
2010-12-27i965: Flatten if-statements beyond depth 16 on pre-gen6.Kenneth Graunke
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.
2010-12-25intel: Only do frame throttling at glFlush time when using frontbuffer.Eric Anholt
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)
2010-12-24i965: use align1 access mode for instructions with execSize=1 in VSXiang, Haihao
All operands must be 16-bytes aligned in aligh16 mode. This fixes l_xxx.c in oglconform.
2010-12-24i965: fix register region descriptionXiang, Haihao
This fixes brw_eu_emit.c:179: validate_reg: Assertion `width == 1' failed.
2010-12-23intel: Remove unnecessary headers.Vinson Lee
2010-12-23i965: Remove unnecessary headers.Vinson Lee
2010-12-23i965: Keep around a copy of the VS constant surface dumping code.Eric Anholt
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.
2010-12-23i965: Correct the dp_read message descriptor setup on g4x.Eric Anholt
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.
2010-12-23i965: upload multisample state for fragment program changeZhenyu Wang
This makes conformance tests stable on sandybridge D0 to track multisample state before SF/WM state.
2010-12-23i965: Use MI_FLUSH_DW for blt ring flush on sandybridgeZhenyu Wang
Old MI_FLUSH command is deprecated on sandybridge blt.
2010-12-22i965: explicit tell header present for fb write on sandybridgeZhenyu Wang
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.
2010-12-21i965: Avoid using float type for raw moves, to work around SNB issue.Eric Anholt
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(!)
2010-12-21intel: Check for unsupported texture when finishing using as a render targetChris Wilson

2010-12-16r600c : inline vertex format is not updated in an app, switch to use vfetch ↵richard
constants. For the 7.9 and 7.10 branches as well.
2010-12-16intel: Support glCopyTexImage() from XRGB8888 to ARGB8888.Eric Anholt
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.
2010-12-16intel: Try to sanely check that formats match for CopyTexImage.Eric Anholt
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.
2010-12-16intel: Drop commented intel_flush from copy_teximage.Eric Anholt
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/.
2010-12-16intel: Update renderbuffers before looking up CopyTexImage's read buffer.Eric Anholt
Not fixing a particular bug, just noticed by code inspection.
2010-12-16i965: Set the alternative floating point mode on gen6 VS and WM.Eric Anholt
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)
2010-12-16i915: Fix INTEL_DEBUG=wm segmentation faultShuang He
The program should be disassembled after it's uploaded
2010-12-13i965: Add support for using the BLT ring on gen6.Eric Anholt
2010-12-13i965: Improve the hacks for ARB_fp scalar^scalar POW on gen6.Eric Anholt
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
2010-12-13i965: Fix gl_FragCoord.z setup on gen6.Eric Anholt
Fixes glsl-bug-22603.
2010-12-13i956: Fix the old FP path fragment position setup on gen6.Eric Anholt
Fixes fp-arb-fragment-coord-conventions-none
2010-12-13i965: Fix ARL to work on gen6.Eric Anholt
RNDD isn't one of the instructions that can do conversion from execution type to destination type. Fixes glsl-vs-arrays-3.
2010-12-13intel: Include stdbool so we can stop using GLboolean when we want to.Eric Anholt
This requires shuffling the driconf XML macros around, since they use true and false tokens expecting them to not get expanded to anything.
2010-12-11r300/compiler: fix swizzle lowering with a presubtract source operandMarek Olšák
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.
2010-12-11r300/compiler: fix LIT in VSMarek Olšák
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.
2010-12-10i965: Put common info on converting MESA_FORMAT to BRW_FORMAT in a table.Eric Anholt
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.
