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.
2011-01-04i965: 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
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: 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.
2010-12-24i965: 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.
2010-12-23i965: 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.
2010-12-22i965: 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(!)
2010-12-16i965: 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)
2010-12-13i965: 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.
2010-12-10i965: 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.
2010-12-10i965: support for two-sided lighting on SandybridgeXiang, Haihao
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.
2010-12-09i965: Add support for gen6 reladdr VS constant loading.Eric Anholt
2010-12-09i965: Add support for gen6 constant-index constant loading.Eric Anholt
2010-12-09intel: Set the swizzling for depth textures using the GL_RED depth mode.Eric Anholt
Fixes depth-tex-modes-rg.
2010-12-09i965: Silence uninitialized variable warning.Vinson Lee
Fixes this GCC warning. brw_fs.cpp: In function 'brw_reg brw_reg_from_fs_reg(fs_reg*)': brw_fs.cpp:3255: warning: 'brw_reg' may be used uninitialized in this function
2010-12-09i965: remove unused variable since brw_wm_glsl.c removal.Eric Anholt
2010-12-09i965: Set render_cache_read_write surface state bit on gen6 constant surfs.Eric Anholt
This is said to be required in the spec, even when you aren't doing writes.
2010-12-09i965: Set up the correct texture border color state struct for Ironlake.Eric Anholt
This doesn't actually fix border color on Ironlake, but it appears to be a requirement, and gen6 needs it too.
2010-12-09i965: Clean up VS constant buffer location setup.Eric Anholt
2010-12-09i965: Fix VS constants regression pre-gen6.Eric Anholt
Last minute change for gen6 with 0 used params dropped the multiply.
2010-12-08i965: Drop push-mode reladdr constant loading and always use constant_map.Eric Anholt
This eases the gen6 implementation, which can only handle up to 32 registers of constants, while likely not penalizing real apps using reladdr since all of those I've seen also end up hitting the pull constant buffer. On gen6, the constant map means that simple NV VPs fit under the 32-reg limit and now succeed. Fixes around 10 testcases.
2010-12-08i965: Drop KIL_NV from the ff/ARB_fp path since it was only used for GLSL.Eric Anholt
2010-12-08i965: Use the new pixel mask location for gen6 ARB_fp KIL instructions.Eric Anholt
Fixes: fp-kil fp-generic/kil-swizzle.
2010-12-08i965: Set the render target index in gen6 fixed-function/ARB_fp path.Eric Anholt
Fixes: fbo-drawbuffers2-blend fbo-drawbuffers2-colormask
2010-12-08i965: Set up the per-render-target blend state on gen6.Eric Anholt
This will let us get EXT_draw_buffers2 blending and colormasking working.
2010-12-08i965: Set up the color masking for the first drawbuffer on gen6.Eric Anholt
Fixes glean/maskedClear
2010-12-07i965: Don't try to store gen6 (float) blend constant color in bytes.Eric Anholt
Fixes glean/blendFunc
2010-12-07i965: Fix flipped value of the not-embedded-in-if on gen6.Eric Anholt
Fixes: glean/glsl1-! (not) operator (1, fail) glean/glsl1-! (not) operator (1, pass)
2010-12-07i965: Work around gen6 ignoring source modifiers on math instructions.Eric Anholt
With the change of extended math from having the arguments moved into mrfs and handed off through message passing to being directly hooked up to the EU, it looks like the piece for doing source modifiers (negate and abs) was left out. Fixes: fog-modes glean/fp1-ARB_fog_exp test glean/fp1-ARB_fog_exp2 test glean/fp1-Computed fog exp test glean/fp1-Computed fog exp2 test ext_fog_coord-modes
2010-12-07i965: Add disabled debug code for dumping out the WM constant payload.Eric Anholt
This can significantly ease thinking about the asm.
2010-12-07i965: Correctly emit constants for aggregate types (array, matrix, struct)Ian Romanick
Previously the code only handled scalars and vectors. This new code is modeled somewhat after similar code in ir_to_mesa. Reviewed-by: Eric Anholt <eric@anholt.net>
2010-12-07i965: Always hand the absolute value to RSQ.Eric Anholt
gen6 builtin RSQ apparently clamps negative values to 0 instead of returning the RSQ of the absolute value like ARB_fragment_program desires and pre-gen6 apparently does. Fixes: glean/fp1-RSQ test 2 (reciprocal square root of negative value) glean/vp1-RSQ test 2 (reciprocal square root of negative value)
2010-12-07i965: Handle saturates on gen6 math instructions.Eric Anholt
We get saturate as an argument to brw_math() instead of as compile state, since that's how the pre-gen6 send instructions work. Fixes fp-ex2-sat.
2010-12-07i965: Fix comment about gen6_wm_constants.Eric Anholt
This is the push constant buffer, not the pull constants.
