2009-06-17intel: Use FRONT_AND_BACK for StencilOp as well.Eric Anholt
(cherry picked from commit 64980125c76b05501a6fe7fe20fe52438f459129)
2009-06-17intel: Use GL_FRONT_AND_BACK for stencil clearing.Eric Anholt
This comes from a radeon-rewrite fallback fix, but may also fix stencil clear failure when the polygon winding mode is flipped. (cherry picked from commit d866abeffc7e4a29736fa35fb8ac09c3a28a44d6)
2009-06-17intel: Skip the DRI2 renderbuffer update when doing Viewport on an FBO.Eric Anholt
(cherry picked from commit d4a42b0ce6455d03be70aa56aacd779be193aca4)
2009-06-17intel: Map write-only buffer objects through the GTT when possible.Eric Anholt
This looks to be a win of a few percent in cairogears with new vbo code, thanks to not polluting caches. (cherry picked from commit aa422b262509bc0763a50f63a51a1730139ea52f)
2009-06-17mesa: rework viewport/scissor initialization codeBrian Paul
The first time a context is bound to a drawable, the viewport and scissor bounds are initialized to the buffer's size. This is actually a bit tricky. A new _mesa_check_init_viewport() function is called in several places to check if the viewport has been initialized. We also use a new ctx->ViewportInitialized flag instead of the overloaded ctx->FirstTimeCurrent flag.
2009-06-17mesa: added null ptr check in Fake_glXCreatePixmap()Brian Paul
Fixes segfault in progs/xdemos/glxgears_pixmap.c
2009-06-17GLX: attempt to fix glean makeCurrent test cases.Brian Paul
Two parts to this: One we don't keep pointers to possibly freed memory anymore once we unbind the drawables from the context. Brian I need to figure out what the comment you made there, can we get a glean/piglit test so we can fix it properly? If the new gc is the same as the oldGC, we call the unbind even though we just bound it in that function. doh. (cherry picked from master, commit 77506dac8e81e9548a7e9680ce367175fe5747af)
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...
2009-06-16mesa: fix incorrect viewport clamping in _mesa_set_viewport()Brian Paul
A 0 by 0 viewport size is legal. Don't clamp against lower bound of one. The error checking earlier in the function prevents negative values.
2009-06-16mesa: fix REMAINDER() macroBrian Paul
The results were incorrect for some negative values of A. See bug 21872.
2009-06-15intel: Release fb backing regions in intelDestroyBuffer()Shuang He
Fixes memory leak when destroying framebuffers.

2009-06-12mesa: Enable uploads of only depth to z24s8 texturesJakob Bornecrantz
2009-06-11mesa: rework vertex shader output / fragment shader input attribute matchingBrian Paul
Before, if a vertex shader's outputs didn't exactly match a fragment shader's inputs we could wind up with invalid TGSI shader declarations. For example: Before patch: DCL OUT[0], POSITION DCL OUT[1], COLOR[1] DCL OUT[2], GENERIC[0] DCL OUT[3], GENERIC[0] <- note duplicate [0] DCL OUT[4], GENERIC[2] After patch: DCL OUT[0], POSITION DCL OUT[1], COLOR[1] DCL OUT[2], GENERIC[0] DCL OUT[3], GENERIC[1] DCL OUT[4], GENERIC[2]
2009-06-11mesa: add default function for ctx->Driver.CheckQuery() hookBrian Paul

2009-06-11st/mesa: fix typo s/BFC0/BFC1/Brian Paul
2009-06-11vbo: fix assertion, #define IMM_BUFFER_NAMEBrian Paul
This was sometimes seen when Glean exited upon test failure when using Gallium.
2009-06-11mesa: Only do read write when we don't have a depth value to writeJakob Bornecrantz
2009-06-11mesa: Take the format from the right structure.José Fonseca
2009-06-11meas: Use a read/write transfer when writing stencil component, but not ↵José Fonseca
touching the depth component.
2009-06-10mesa: Reverse s8z24 into z24s8 as required by EXT_packed_depth_stencil.José Fonseca
Actually, after spotting this problem, I realized this is unreachable code. However don't bother to enable this fast path now, given the normal path is working just fine.
2009-06-10mesa: Fix typo in bitmask.José Fonseca
2009-06-10mesa: Fix draw_stencil_pixels for PIPE_FORMAT_Z24S8_UNORM.José Fonseca
Reversed component order. This fixes glean depthStencil test failures for PIPE_FORMAT_Z24S8_UNORM visuals.
2009-06-10glsl: fix warnings, update comments, s/TRUE/GL_TRUE/Brian Paul
(cherry picked from master, commit 7fdd64ab29576e607434fb8c82ddfa61e8ea6aa8)
2009-06-10glsl: Handle continuation characters in preprocessor.Brian Paul
(cherry picked from master, commit cc22620e4b11425997f3bc1fc70f4c88cec22d2e)
2009-06-10swrast: fix state validation bug for changing program constantsBrian Paul
Add _NEW_PROGRAM_CONSTANTS to _SWRAST_NEW_DERIVED. This makes sure that we update the fragment shader's constants when state vars (such as point size) changes. Fixes the progs/glsl/points.c demo.
2009-06-10glsl: Fix symbol replacement handling in preprocessor.Brian Paul
(cherry picked from master, commit d9617deb008b75f4a605a30408aeb1948139c33e)
2009-06-10mesa: disable texture unit error check in _mesa_MatrixMode()Brian Paul
See comments for details.
2009-06-10mesa: Single precision constants.José Fonseca
2009-06-10mesa: Pure software accum buffer.José Fonseca
The existing implementation was already implemented on software, but relied on the pipe driver to always support the R16G16B16A16_SNORM format. This patch eliminates that, without prejudice against a future hardware-only implementation. It also avoids some of the short <-> float conversions, and only does a read transfer of the color buffer on GL_RETURN if absolutely necessary.
2009-06-09mesa/st: fix tracking of mapped buffer rangesKeith Whitwell
In st_bufferobj_map_range(), set obj->Offset consistently with its usage elsewhere.
2009-06-09glsl: Expand nested preprocessor macros.Brian Paul
(cherry picked from master, commit ef8caec29ae73bb2bbeb48f0578d839ef29348cd)

2009-06-08st/mesa: remove invalid assertionBrian Paul
It's legal for ARB_vertex_program programs to not write to result.position. The results are undefined in that case. This assertion was causing us to abort/exit though.
2009-06-08mesa: Use matching signedness for the counter as upper bound.José Fonseca
2009-06-08mesa: Allocate tokens from the heap.José Fonseca
The recent increase ST_MAX_SHADER_TOKENS to 8K causes stack overflows on windows. Failure to allocate is not being propagated to the caller. This is not a regression since the previous _mesa_malloc result wasn't being checked as well. Unfortunately it is not easy to fix, as the callers of these functions do not have failure propagation mechanism either, and so on. So leaving a just fixme note for now.
2009-06-08mesa: better error message for invalid texture unit indexBrian Paul
2009-06-08mesa: bump MAX_PROGRAM_ENV_PARAMS from 128 to 256Brian Paul
Also, MAX_NV_VERTEX_PROGRAM_PARAMS should be 96, not 128 (or 256).
2009-06-08mesa/vbo: drop all references to vbo on destroyKeith Whitwell
We were adding references to the input arrays, but failing to drop them on destruction. This could lead to a 64kb buffer being leaked each context destruction.
2009-06-08mesa: EXT_vertex_array_bgra fixesBrian Paul
1) Pass the correct format when calling update_array in _mesa_VertexAttribPointerARB. 2) glVertexAttribPointerNV accepts GL_BGRA format too. 3) raise INVALID_VALUE error when format is BGRA and normalized is false in glVertexAttribPointerARB (cherry picked from commit 4adb190a162c5ed0684a8616331344caadba4010)
2009-06-05mesa: bump version to 7.5-rc3Brian Paul
2009-06-04osmesa: Allow building standalone in all three channel widthsDan Nicholson
autoconf had been designating the 8 bit libOSMesa as the default standalone osmesa, but the Makefile expected it to be linked to libGL. Fix up the osmesa Makefile so that it allows any of the combinations of standalone and channel width to be built. Fixes bug #21980. (cherry picked from commit 7441dcd90b01df8351026af8bbb50e11bb86071a)
