2010-11-03intel: Annotate debug printout checks with unlikely().Eric Anholt
This provides the optimizer with hints about code hotness, which we're quite certain about for debug printouts (or, rather, while we developers often hit the checks for debug printouts, we don't care about performance while doing so).
2010-10-21i965: Correct scratch space allocation.Eric Anholt
One, it was allocating increments of 1kb, but per thread scratch space is a power of two. Two, the new FS wasn't getting total_scratch set at all, so everyone thought they had 1kb and writes beyond 1kb would go stomping on a neighbor thread. With this plus the previous register spilling for the new FS, glsl-fs-convolution-1 passes.
2010-10-19i965: Tell the shader compiler when we expect depth writes for gen6.Eric Anholt
This fixes hangs in some Z-writes-in-shaders tests, though other pieces don't come out correctly. Bug #30392: hang in fbo-fblit-d24s8. (still fails with bad color drawn to some targets)
2010-10-13Drop GLcontext typedef and use struct gl_context insteadKristian Høgsberg
2010-10-03i965: Fix glean/texSwizzle regression in previous commit.Eric Anholt
Easy enough patch, who needs a full test run. Oh, that's right. Me.
2010-10-02i965: Set up swizzling of shadow compare results for GL_DEPTH_TEXTURE_MODE.Eric Anholt
The brw_wm_surface_state.c handling of GL_DEPTH_TEXTURE_MODE doesn't apply to shadow compares, which always return an intensity value. The texture swizzles can do the job for us. Fixes: glsl1-shadow2D(): 1 glsl1-shadow2D(): 3
2010-09-28i965: Add support for attribute interpolation on Sandybridge.Eric Anholt
Things are simpler these days thanks to barycentric interpolation parameters being handed in in the payload.
2010-09-21i965: Track the windowizer's dispatch for kill pixel, promoted, and OQEric Anholt
Looks like the problem was we weren't passing the depth to the render target as expected, so the chip would wedge. Fixes GPU hang in occlusion-query-discard. Bug #30097
2010-09-01i965: DP2 produces a scalar result like DP3, DP4, etc.Eric Anholt
Fixes glsl-fs-dot-vec2-2.
2010-08-26i965: Start building direct GLSL2 IR to 965 assembly codegen.Eric Anholt
Our channel-expressions and vector-splitting changes now happen into a private copy of the IR that we maintain for ourselves. Uniform assignment still happens by the core, so we continue using Mesa IR generation not just for swrast fallbacks but also for uniform values (since there's no storage for their contents other than shader_program->FragmentProgram->Parameters->ParameterValues). And most importantly, at the moment no actual codegen is hooked up other than emitting our favorite color to the framebuffer.
2010-08-13intel: Remove include of texmem.h, since we haven't used it in ages.Eric Anholt
2010-06-08intel: Change dri_bo_* to drm_intel_bo* to consistently use new API.Eric Anholt
The slightly less mechanical change of converting the emit_reloc calls will follow.
2010-02-19Replace _mesa_malloc, _mesa_calloc and _mesa_free with plain libc versionsKristian Høgsberg
2010-01-26i965: Fix fp fragment.position handling and enable HW part of ARB_fcc.Eric Anholt
As with swrast, this fixes the default pixel center behavior which was broken, and implements the previous behavior for integer. Fixes piglit fp-arb-fragment-coord-conventions-none. The extension won't be exposed until we get the GLSL part implemented. The DRI1 origin_x/y parts are dropped since they're no longer relevant.

2010-01-22i965: Remove unnecessary headers.Vinson Lee
2010-01-19i965: Allow for variable-sized auxdata in the state cache.Eric Anholt
Everything has been constant-sized until now, but constant buffer handling changes will make us want some additional variable sized array.
2009-11-21i965: Fix several memory leaks on exit.Eric Anholt
Bug #25194.
2009-11-17Merge branch 'outputswritten64'Ian Romanick
Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

2009-11-10i965: avoid memsetting all the BRW_WM_MAX_INSN arrays for every compile.Eric Anholt
For an app that's blowing out the state cache, like sauerbraten, the memset of the giant arrays ended up taking 11% of the CPU even when only a "few" of the entries got used. With this, the WM program compile drops back down to 1% of CPU time. Bug #24981 (bisected to BRW_WM_MAX_INSN increase).
2009-10-29i965: avoid shader translation on window resizeBrian Paul
If the fragment shader doesn't use FRAG_ATTRIB_WPOS (gl_FragCoord) we don't need to worry about the window size and origin in brw_wm_populate_key(). This avoids re-generating the i965 shader code when a window is resized. Issue spotted by Keith Whitwell.
2009-10-29i965: don't use context state in emit_fb_write()Brian Paul
Put the state that we care about in the hash key. Issue spotted by Keith Whitwell.
2009-10-05drivers: don't include texformat.hBrian Paul
And remove other unneeded #includes while we're at it.
2009-09-30mesa: replace gl_texture_format with gl_formatBrian Paul
Now gl_texture_image::TexFormat is a simple MESA_FORMAT_x enum. ctx->Driver.ChooseTexture format also returns a MESA_FORMAT_x. gl_texture_format will go away next.
2009-08-12i965: Correct brw_wm_nr_args for WM_DELTAXY and WM_PIXELXY.Eric Anholt
2009-08-12i965: Store the dispatch width in the WM compile struct.Eric Anholt
I'll be using this in merging brw_wm_emit.c and brw_wm_glsl.c
2009-08-05i965: Fix source depth reg setting for FSes reading and writing to depth.Eric Anholt
For some IZ setups, we'd forget to account for the source depth register being present, so we'd both read the wrong reg, and write output depth to the wrong reg. Bug #22603.

2009-06-16i965: fix bugs in projective texture coordinatesBrian Paul
For the TXP instruction we check if the texcoord is really a 4-component atttibute which requires the divide by W step. This check involved the projtex_mask field. However, the projtex_mask field was being miscalculated because of some confusion between vertex program outputs and fragment program inputs. 1. Rework the size_masks calculation so we correctly set bits corresponding to fragment program input attributes. 2. Rename projtex_mask to proj_attrib_mask since we're interested in more than just texcoords (generic varying vars too). 3. Simply the indexing of the size_masks and proj_attrib_mask fields. 4. The tracker::active[] array was mis-dimensioned. Use MAX_PROGRAM_TEMPS instead of a magic number. 5. Update comments, add new assertions. With these changes the Lightsmark demo/benchmark renders correctly, until we eventually hit a GPU lockup...
2009-06-12i965: interpolate colors with perspective correction by defaultBrian Paul
...rather than with linear interpolation. Modern hardware should use perspective-corrected interpolation for colors (as for texcoords). glHint(GL_PERSPECTIVE_CORRECTION_HINT, mode) can be used to get linear interpolation if mode = GL_FASTEST.
2009-05-14i965: Fix register allocation of GLSL fp inputs.Eric Anholt
Before, if the VP output something that is in the attributes coming into the WM but which isn't used by the WM, then WM would end up reading subsequent varyings from the wrong places. This was visible with a GLSL demo using gl_PointSize in the VS and a varying in the WM, as point size is in the VUE but not used by the WM. There is now a regression test in piglit, glsl-unused-varying.
2009-05-08i965: fix segfault on low memory conditionsRobert Ellison
When out of memory (in at least one case, triggered by a longrunning memory leak), this code will segfault and crash. By checking for the out-of-memory condition, the system can continue, and will report the out-of-memory error later, a much preferable outcome.

2009-03-23i965: Fix glFrontFacing in twoside GLSL demo.Eric Anholt
This also cuts instructions by just using the existing bit in the payload rather than computing it from the determinant in the SF unit and passing it as a varying down to the WM. Something still goes wrong with getting the backface color right, but a simpler shader appears to get the right result.
2009-03-06i965: avoid unnecessary calls to brw_wm_is_glsl()Brian Paul
This function scans the shader to see if it has any GLSL features like conditionals and loops. Calling this during state validation is expensive. Just call it when the shader is given to the driver and save the result. There's some new/temporary assertions to be sure we don't get out of sync on this.
2009-03-02mesa: use Stencil._Enabled field instead of Stencil.EnabledBrian Paul
2009-02-28mesa: rename, reorder FRAG_RESULT_x tokensBrian Paul
s/FRAG_RESULT_DEPR/FRAG_RESULT_DEPTH/ s/FRAG_RESULT_COLR/FRAG_RESULT/COLOR/ Remove FRAG_RESULT_COLH (NV half-precision) output since we never used it. Next, we might merge the COLOR and DATA outputs (COLOR0, COLOR1, etc).

2009-01-28i965: implement GL_EXT_texture_swizzleBrian Paul
If the texture swizzle is not XYZW (no-op) add an extra MOV instruction after the TEX instruction to rearrange the components.
2009-01-28i965: minor improvements in brw_wm_populate_key()Brian Paul
2009-01-23Track two sets of back-face stencil stateIan Romanick
Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt
