* i965: Don't emit bad packets when no VBs are referenced.Eric Anholt2009-09-041-0/+22
| | | | | | | | | | 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)
* i965: Calculate enabled[] and nr_enabled once and re-use the values.Eric Anholt2009-09-042-29/+18
| | | | | The code duplication bothered me. (cherry picked from commit 9b9cb30d128fc5f1ba77287696ecd508e640efde)
* i965: Set the max index buffer address correctly according to the docs.Eric Anholt2009-09-041-1/+1
| | | | | It's the last addressable byte, not the byte after the end of the buffer. (cherry picked from commit b72dea5441e8e9226dabf1826fa3bc129c7bc281)

* st/mesa: fix glCopyPixels(GL_STENCIL_INDEX) inverted positionBrian Paul2009-09-031-0/+4
| | | | | If the renderbuffer orientation is Y=0=TOP we need to invert the dstY position.
* st/mesa: Do GL_RGBA->GL_RGB texsubimage on hardwareKeith Whitwell2009-09-021-14/+51
| | | | | | | | | | | | 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.
* util: add version of u_blit_pixels which takes a writemaskKeith Whitwell2009-09-024-15/+100
| | | | Values outside the writemask are set in the destination to {0,0,0,1}

* swrast: fix selection/feedback regressionBrian Paul2009-08-311-1/+1
| | | | | This fixes a conform selection/feedback regression introduced by commit 8f4d66c5f893b49eb3973aa3b31a856314c045c7
* swrast: can't use deferred texture/shading if using KIL instructionBrian Paul2009-08-311-0/+3
| | | | | | 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.

* mesa: fix saturation logic in emit_texenv()Brian Paul2009-08-311-1/+7
| | | | | | 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).

* mesa: fix 32bit cross compilation on a 64bit machineMarc Dietrich2009-08-312-1/+2
| | | | | | | | | | | 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.

* progs/glsl: change samplers.c to better test sampler/texture indexingBrian Paul2009-08-261-4/+12
| | | | | Now the left half is yellow and the right half is red, with the gradients going in opposite directions.
* glsl: fix bug in sampler array indexingBrian Paul2009-08-261-3/+7
| | | | | | | | | 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.
* ARB prog: Set error instead of falling through with incorrect valueBrian Paul2009-08-241-0/+3
| | | | | | | | | | | | | | 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)

* xlib: fix single buffer window resize bugBrian Paul2009-08-241-0/+1
| | | | | | 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...

* st/mesa: flush bitmap cache if Z value changesBrian Paul2009-08-211-5/+11
| | | | | | | 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 <[email protected]>
* tgsi: check for SOA dependencies in SSE and PPC code generatorsBrian Paul2009-08-202-0/+8
| | | | Fall back to interpreter for now. This doesn't happen very often.
* tgsi: handle SOA dependencies for MOV/SWZBrian Paul2009-08-202-14/+40
| | | | | | | | | | | | | | | | | | | | | | 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.
* tgsi: added tgsi_full_instruction::Flags fieldBrian Paul2009-08-202-0/+3
