2010-10-15st/mesa: use GLuint to avoid problem w/ uint not defined on mingw32Brian Paul
2010-10-15st/mesa: reformatting in st_cb_drawpixels.cBrian Paul
2010-10-15st/mesa: fix regressions in glDrawPixels(GL_STENCIL_INDEX)Brian Paul
We need to keep track of three different fragment shaders: Z-only, stencil- only, and Z+stencil. Before, we were only keeping track of the first one we encountered.
2010-10-15i965: Set the type of the null register to fix gen6 FS comparisons.Eric Anholt
We often use reg_null as the destination when setting up the flag regs. However, on gen6 there aren't general implicit conversions to destination types from src types, so the comparison to produce the flag regs would be done on the integer result interpreted as a float. Hilarity ensued. Fixes 20 piglit cases.
2010-10-15i965: Fix indentation after commit 3322fbafIan Romanick
2010-10-15mesa: Add missing header to shaderobj.h.Vinson Lee
Include compiler.h for ASSERT symbol.
2010-10-14glsl: Slightly change the semantic of _LinkedShadersIan Romanick
Previously _LinkedShaders was a compact array of the linked shaders for each shader stage. Now it is arranged such that each slot, indexed by the MESA_SHADER_* defines, refers to a specific shader stage. As a result, some slots will be NULL. This makes things a little more complex in the linker, but it simplifies things in other places. As a side effect _NumLinkedShaders is removed. NOTE: This may be a candidate for the 7.9 branch. If there are other patches that get backported to 7.9 that use _LinkedShader, this patch should be cherry picked also.
2010-10-14i965: Fix texturing on pre-gen5.Eric Anholt
I broke it in 06fd639c519214b6ebcbf29127b6d9ed429f8641 by only testing 2 generations of hardware :(
2010-10-14mesa: remove post-convolution width/height varsBrian Paul
These were left-over bits from when convolution was removed.
2010-10-14i965: Add support for ir_unop_round_even via the RNDE instruction.Kenneth Graunke
2010-10-14glsl: Add a new ir_unop_round_even opcode for GLSL 1.30's roundEven.Kenneth Graunke
Also, update ir_to_mesa's "1.30 is unsupported" case to "handle" it.
2010-10-14i965: Clean up a warning in the old fragment backend.Kenneth Graunke
Hopefully this code can just go away soon.
2010-10-14i965: Enable the new FS backend on pre-gen6 as well.Eric Anholt
It is now to the point where we have no regressing piglit tests. It also fixes Yo Frankie! and Humus DynamicBranching, probably due to the piglit bias tests that work that didn't on the Mesa IR backend. As a downside, performance takes about a 5-10% performance hit at the moment (e.g. nexuiz 19.8fps -> 18.8fps), which I plan to resolve by reintroducing 16-wide fragment shaders where possible. It is a win, though, for fragment shaders using flow control.
2010-10-14i965: Correctly emit the RNDZ instruction.Kenneth Graunke
Simply using RNDU, RNDZ, or RNDE does not produce the desired result. Rather, the RND* instructions place a value in the destination register that may be 1 less than the correct answer. They can also set per-channel "increment bits" in a flag register, which, if set, mean dest needs to be incremented by 1. A second instruction - a predicated add - completes the job. Notably, RNDD always produces the correct answer in a single instruction. Fixes piglit test glsl-fs-trunc.
2010-10-14i965: Use RNDZ for ir_unop_trunc in the new FS.Kenneth Graunke
The existing code used RNDD, which rounds down, rather than toward zero.
2010-10-14i965: Use logical-not when emitting ir_unop_ceil.Kenneth Graunke
Fixes piglit test glsl-fs-ceil.
2010-10-14i965: Add peepholing of conditional mod generation from expressions.Eric Anholt
This cuts usually 2 out of 3 instructions for flag reg generation (if statements, conditional assignment) by producing the conditional mod in the expression representing the boolean value. Fixes glsl-fs-vec4-indexing-temp-dst-in-nested-loop-combined (register allocation no longer fails for the conditional generation proliferation)
2010-10-14i965: Add a function for handling the move of boolean values to flag regs.Eric Anholt
This will be a place to peephole comparisions directly to the flag regs, and for now avoids using MOV with conditional mod on gen6, which is now illegal.
2010-10-14Only install vtxfmt tables for OpenGLKristian Høgsberg
GLES1 and GLES2 install their own exec pointers and don't need the Save table. Also, the SET_* macros use different indices for the different APIs so the offsets used in vtxfmt.c are actually wrong for the ES APIs.
2010-10-14i965: Add a pass to the FS to split virtual GRFs to float channels.Eric Anholt
Improves nexuiz performance 0.91% (+/- 0.54%, n=8)
2010-10-14i965: Update the live interval when coalescing regs.Eric Anholt
2010-10-14i965: Set class_sizes[] for the aligned reg pair class.Eric Anholt
So far, I've only seen this be a valgrind warning and not a real failure.
2010-10-14Drop the "neutral" tnl moduleKristian Høgsberg
Just always check for FLUSH_UPDATE_CURRENT and call Driver.BeginVertices when necessary. By using the unlikely() macros, this ends up as a 10% performance improvement (for isosurf, anyway) over the old, complicated function pointer swapping.
2010-10-14Revert "i965: fallback lineloop on sandybridge for now"Zhenyu Wang
This reverts commit 73dab75b4165f7d2214a68d4ba8e3cb7aab9b4ac.
2010-10-14i965: Fix GS hang on SandybridgeZhenyu Wang
Don't use r0 for FF_SYNC dest reg on Sandybridge, which would smash FFID field in GS payload, that cause later URB write fail. Also not use r0 in any URB write requiring allocate.
2010-10-13i965: Add support for rescaling GL_TEXTURE_RECTANGLE coords to new FS.Eric Anholt
2010-10-13mesa: Clean up various 'unused parameter' warnings in shaderapiIan Romanick
2010-10-13mesa: Clean up two 'comparison between signed and unsigned' warningsIan Romanick
2010-10-13mesa: Refactor validation of shader targetsIan Romanick
Actually validate that the implementation supports the particular shader target as well. Previously if a driver only supported vertex shaders, for example, glCreateShaderObjectARB would gladly create a fragment shader. NOTE: this is a candidate for the 7.9 branch.
2010-10-13mesa: Silence unused variable warningIan Romanick
2010-10-13x11: fix breakage from gl_config::visualType removalBrian Paul
2010-10-13Drop GLcontext typedef and use struct gl_context insteadKristian Høgsberg
2010-10-13Drop GLframebuffer typedef and just use struct gl_framebufferKristian Høgsberg
2010-10-13Rename GLvisual and __GLcontextModes to struct gl_configKristian Høgsberg
2010-10-13gl: Remove unused GLcontextModes fieldsKristian Høgsberg
2010-10-13Get rid of GL/internal/glcore.hKristian Høgsberg
__GLcontextModes is always only used as an implementation internal struct at this point and we shouldn't install glcore.h anymore. Anything that needs __GLcontextModes should just include the struct in its headers files directly.
2010-10-12tdfx: Silence unused variable warning on non-debug builds.Vinson Lee
Fixes this GCC warning. tdfx_texman.c: In function 'tdfxTMMoveOutTM_NoLock': tdfx_texman.c:897: warning: unused variable 'shared'
2010-10-12r300: Silence uninitialized variable warning.Vinson Lee
Fixes this GCC warning. r300_state.c: In function 'r300InvalidateState': r300_state.c:2247: warning: 'hw_format' may be used uninitialized in this function r300_state.c:2247: note: 'hw_format' was declared here

2010-10-12mesa: remove assertion w/ undeclared variable texelBytesBrian Paul
2010-10-13st/mesa: enable stencil shader export extension if supportedDave Airlie
2010-10-13glsl: add support for shader stencil exportDave Airlie
This adds proper support for the GL_ARB_shader_stencil_export extension to the GLSL compiler. Thanks to Ian for pointing out where I need to add things.
2010-10-13st/mesa: use shader stencil export to accelerate shader drawpixels.Dave Airlie
If the pipe driver has shader stencil export we can accelerate DrawPixels using it. It tries to pick an S8 texture and works its way to X24S8 and S8X24 if that isn't supported.
2010-10-13st/mesa: add option to choose a texture format that we won't render to.Dave Airlie
We need a texture to put the drawpixels stuff into, an S8 texture is less memory/bandwidth than the 32-bit X24S8, but we might not be able to render directly to an S8, so this lets us specify we won't be rendering to this texture.
2010-10-13mesa: improve texstore for 8/24 formats and add texstore for S8.Dave Airlie
this improves mesa texstore for 8/24 so it can create S24X8/X24S8 variants by keeping the depth bits static. it also adds a texstore for S8 so we can write out an S8 texture to use in the sampler for accel draw pixels to save memory bw. The logic seems sound here, I've worked it out a few times on paper, though it would be good to have some review. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-10-13mesa: add support for FRAG_RESULT_STENCIL.Dave Airlie
this is needed to add support for stencil shader export. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-10-12i965: Don't rebase the index buffer to min 0 if any arrays are in VBOs.Eric Anholt
There was a check to only do the rebase if we didn't have everything in VBOs, but nexuiz apparently hands us a mix of VBOs and arrays, resulting in blocking on the GPU to do a rebase. Improves nexuiz 800x600, high-settings performance on my Ironlake 41% (+/- 1.3%), from 14.0fps to 19.7fps.
2010-10-12intel: Allow CopyTexSubImage to InternalFormat 3/4 textures, like RGB/RGBA.Eric Anholt
The format selection of the CopyTexSubImage is pretty bogus still, but this at least avoids software fallbacks in nexuiz, bringing performance from 7.5fps to 12.8fps on my machine.
2010-10-12i965: Fix missing "break;" in i2b/f2b, and missing AND of CMP result.Eric Anholt
Fixes glsl-fs-i2b.
