2009-09-04intel: Update Mesa state before span setup in glReadPixels.Eric Anholt
We could have mapped the wrong set of draw buffers. Noticed while looking into a DRI2 glean ReadPixels issue. (cherry picked from commit afc981ee46791838f3cb83e11eb33938aa3efc83)
2009-09-04intel: Move intel_pixel_read.c to shared for use with i965.Eric Anholt
(cherry picked from commit dcfe0d66bfff9a55741aee298b7ffb051a48f0d3)
2009-09-04i965: Add missing state dependency of sf_unit on _NEW_BUFFERS.Eric Anholt
(cherry picked from commit 99174e7630676307f618c252755a20ba61ad9158)
2009-09-04intel: Align cubemap texture height to its padding requirements.Eric Anholt
(cherry picked from commit a70e1315846cd5e8d6f2b622821ff8262fe7179d) (cherry picked from commit 29e51c3872531366570d032147abad50f8a3c1af)
2009-09-04intel: Align untiled region height to 2 according to 965 docs.Eric Anholt
This may or may not be required pre-965, but it doesn't seem unlikely, and I'd rather be safe. (cherry picked from commit b053474378633249be0e9f24010650ffb816229a)
2009-09-04i965: 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. (cherry picked from commit f44916414ecd2b888c8a680d56b7467ccdff6886)
2009-09-04i965: Respect CondSwizzle in OPCODE_IF.Eric Anholt
Fixes piglit glsl-vs-if-bool and progs/glsl/twoside, and will likely be useful for the looping code. Bug #18992 (cherry picked from commit 78c022acd0b37bf8b32f04313d76255255e769c1) (cherry picked from commit 63d7a2f53fb38e170f4e55f2b599e918edf2c512)
2009-09-04i965: asst clean-ups, etc in brw_vs_emit()Brian Paul
(cherry picked from commit fd7d764514c540987549c3ea88a2d669b0f0ea58)
2009-09-04i965: Emit conditional code updates as required for GLSL VS if statements.Eric Anholt
Previously, we'd be branching based on whatever condition code happened to be laying around. (cherry picked from commit 7007f8b352763af89805f287153cb7972bff0523)
2009-09-04i965: Spell "conditional" correctly.Eric Anholt
2009-09-04i965: Fix RECT shadow sampling by not losing the other texcoords.Eric Anholt
Bug #20821 (cherry picked from commit 191e028de20b2f954621b652aa77b06d0e93652a)
2009-09-04i965: Assert that the offset in the VBO is below the VBO size.Eric Anholt
This avoids sending a bad buffer address to the GPU due to programmer error, and is permitted by the ARB_vbo spec. Note that we still have the opportunity to dereference past the end of the GPU, because we aren't clipping to a correct _MaxElement, but that appears to be harder than it should be. This gets us the 90% solution. Bug #19911. (cherry picked from commit d7430d942f6c7950a92367aeb13b80cf76ccad78)
2009-09-04i965: Even if no VS inputs are set, still load some amount of URB as required.Eric Anholt
See comment on Vertex URB Entry Read Length for VS_STATE. This, combined with the previous three commits, fixes #22945. (cherry picked from commit e340d4f9866db4bae391288e83a630a310b0dd2b)
2009-09-04i965: Make sure the VS URB size is big enough to fit a VF VUE.Eric Anholt
This fix is just from code and docs inspection, but it may fix hangs on some applications. (cherry picked from commit e93848e595176ae0bad3bfe64e0ca63fd089bb72)
2009-09-04i965: Don't emit bad packets when no VBs are referenced.Eric Anholt
It appears that sometimes Mesa (and I suppose a VS could as well) emits a program which references no vertex data, and thus we end up with nr_enabled == 0 even though some VBs are enabled. We'd end up emitting VB/VE packet headers of 0xffffffff in that case, leading to GPU hangs. Bug #22945 (wine with an uncompiled VS) (cherry picked from commit d1fbfd0f962347e4153db3852292d44de5aea863)
2009-09-04i965: Calculate enabled[] and nr_enabled once and re-use the values.Eric Anholt
The code duplication bothered me. (cherry picked from commit 9b9cb30d128fc5f1ba77287696ecd508e640efde)
2009-09-04i965: Set the max index buffer address correctly according to the docs.Eric Anholt
It's the last addressable byte, not the byte after the end of the buffer. (cherry picked from commit b72dea5441e8e9226dabf1826fa3bc129c7bc281)
2009-09-04i965: rename var: s/tmp/vs_inputs/Brian Paul
(cherry picked from commit 840c09fc71542fdfc71edd2a2802925d467567bb)
2009-09-03gallium/xlib: silence unitialized var warningBrian Paul

2009-09-03st/mesa: silence uninitialized var warningsBrian Paul
2009-09-03st/mesa: fix glCopyPixels(GL_STENCIL_INDEX) inverted positionBrian Paul
If the renderbuffer orientation is Y=0=TOP we need to invert the dstY position.
2009-09-02st/mesa: Do GL_RGBA->GL_RGB texsubimage on hardwareKeith Whitwell
State tracker currently backs GL_RGB textures with RGBA almost always. This means we need to maintain A==1 in these textures to give correct GL_RGB sampling results. This change offloads the RGBA->RGB copy to hardware using the new writemask version of u_blit_pixels. More src/dstLogical/dstActual triples could be shifted to hardware by this technique in future patches.
2009-09-02util: add version of u_blit_pixels which takes a writemaskKeith Whitwell
Values outside the writemask are set in the destination to {0,0,0,1}
2009-09-02draw: remove unused variableKeith Whitwell
2009-08-31swrast: fix selection/feedback regressionBrian Paul
This fixes a conform selection/feedback regression introduced by commit 8f4d66c5f893b49eb3973aa3b31a856314c045c7
2009-08-31swrast: can't use deferred texture/shading if using KIL instructionBrian Paul
If the fragment program uses KIL, we have to execute it before z/stencil testing. Otherwise, deferred texture/shading lets us skip shading for pixels that fail z/stencil testing.
2009-08-31mesa: added const qualifiers, move local varBrian Paul
2009-08-31mesa: fix saturation logic in emit_texenv()Brian Paul
We need to clamp/saturate after each texenv stage, not just the last one. Fixes glean texEnv failure for softpipe (and probably other fragment program- based drivers).
2009-08-31mesa: fix 32bit cross compilation on a 64bit machineMarc Dietrich
When cross compiling on a 64bit machine, gen_matypes.c is build for the host machine (64bit) but must generates code for the target machine (32bit). This causes wrong offsets all over the place and crashes googleearth on my machine. Solution is to add -m32 when cross compiling. Attached patch is compatible with linux-x86-32 and autoconf based builds.
2009-08-30glx/x11: Fix glXCreateGLXPixmap for direct rendering.Michel Dänzer
Fixes progs/xdemos/glxpixmap modified to use direct rendering.
2009-08-28util: Reset size to zero when failed to allocate buffer.José Fonseca
2009-08-27swrast: fix incorrect tri culling in selection/feedback mode.Brian Paul
See bug 16866.
2009-08-27mesa: direct program debug output to stderr instead of stdoutmarvin24
2009-08-27gallium/util: added support for SRGB formatsBrian Paul
Fixes glean/texture_srgb failure, bug #23449.
2009-08-27gallium/util: added cases for SRGB formatsBrian Paul
2009-08-26glsl: signal that the program needs to be re-translated when samplers changeBrian Paul
2009-08-26glsl: fix bug in sampler array indexingBrian Paul
Need to add the 'offset' parameter when indexing the parameter array. Before, if we were setting arrays of samplers, we were actually only setting the 0th sampler's value. Because of how progs/glsl/samplers.c is constructed, this wasn't showing up as a failure in the samplers_array output.
2009-08-24ARB prog: Set error instead of falling through with incorrect valueBrian Paul
If a fragment program only parameter was queried of a vertex program (e.g., GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB) no error would be set and a random value would be returned. This caused 'glxinfo -l' to show the same values for GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB, GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB as for GL_MAX_PROGRAM_ENV_PARAMETERS_ARB. This is confusing and incorrect. (cherry picked from master, commit 4bccd693a72a0b42dffc849034263a68e779ca91)
2009-08-24xlib: fix single buffer window resize bugBrian Paul
When a single-buffered window was resized the new window size was never detected. This fix that, but there's still a bug which causes window contents corruption for certain window sizes...
2009-08-24vbo: fix divide by zero exceptionBrian Paul
Fixes bug 23489.
2009-08-24glsl: Silence gcc uninitialized variable warning.Vinson Lee
2009-08-21st/mesa: flush bitmap cache if Z value changesBrian Paul
When adding a new bitmap to the cache we have to check if the Z value is changing and flush first if it is. This is a modified version of a patch from Justin Dou <justin.dou@intel.com>
2009-08-20tgsi: check for SOA dependencies in SSE and PPC code generatorsBrian Paul
Fall back to interpreter for now. This doesn't happen very often.
2009-08-20tgsi: handle SOA dependencies for MOV/SWZBrian Paul
SOA dependencies can happen when a register is used both as a source and destination and the source is swizzled. For example: MOV T, T.yxwz; would expand into: MOV t0, t1; MOV t1, t0; MOV t2, t3; MOV t3, t2; The second instruction will produce the wrong result since we wrote to t0 in the first instruction. We need to use an intermediate temporary to fix this. This will take more work to fix for all TGSI instructions. This seems to happen with MOV instructions more than anything else so fix that case now and warn on others. Fixes piglit glsl-vs-loop test (when not using SSE). See bug 23317.
2009-08-20tgsi: added tgsi_full_instruction::Flags fieldBrian Paul
Users of the parser can make use of this.
2009-08-18tgsi/ppc: we don't implement saturation modes yetBrian Paul
2009-08-18tgsi/sse: we don't implement saturation modes yetBrian Paul
Fixes piglit fp-generic tests/shaders/generic/lrp_sat.fp, bug 23316.
2009-08-18mesa: when emitting vertex program fog, set yzw=0,0,1Brian Paul
Fixes piglit fp-fog failure with gallium.
2009-08-14gallium: Always map for READ flag when DISCARD is not set.José Fonseca
This prevents the driver from discarding a buffer when the whole buffer is mapped for writing, but only a portion is effectively written. This is a temporary fix, because WRITE shouldn't imply DISCARD. The full fix implies using PIPE_BUFFER_USAGE_DISCARD, throughout the code, and will go only into master.
