2009-09-24softpipe: Increase GL_MAX_3D_TEXTURE_SIZE to 256.Vinson Lee1-1/+1
2009-09-24mesa: remove glEnable(GL_DEPTH_BOUNDS_TEST_EXT) check/warningBrian Paul1-5/+0
At the time of the enable there may not be a Z buffer, but one may be attached to the FBO later.
2009-09-24mesa: remove rgbMode check in enable_texture()Brian Paul1-1/+1
If the currently bound FBO isn't yet validated it's possible for rgbMode to be zero so we'll lose the texture enable. This could fix some FBO rendering glitches, but I don't know of any specific instances.
2009-09-23swrast: add lod bias when texture samplingBrian Paul1-2/+7
Mostly fixes progs/demos/lodbias when MESA_TEX_PROG=1. But the LOD still seems off by -1 or so. May be an issue with the params passed to _swrast_compute_lambda()
2009-09-23mesa: don't bias LOD in shader interpreter; do it in swrastBrian Paul1-6/+1
2009-09-23swrast: fix typo in partial derivatives parameter passingBrian Paul1-1/+1
2009-09-23st/mesa: trim calculated userbuffer sizeKeith Whitwell1-3/+9
In get_array_bounds we were previously defining a user buffer sized as (nr_vertices * stride). The trouble is that if the vertex data occupies less than stride bytes, the extra tailing (stride - size) bytes may extend outside the memory actually allocated by the app and caused a segfault. To fix this, define a the buffer bounds to be: ptr .. ptr + (nr-1)*stride + element_size
2009-09-22glx: include string.h to silence missing memset() prototype warningBrian Paul1-0/+1
2009-09-22mesa: fix error message textBrian Paul1-1/+1
2009-09-21GLX: Warn only once about applications calling GLX 1.3 functionsTormod Volden1-6/+14
The warnings introduced in 1f309c40b8065b8729fce631540c66e4b50b84df would pour out generously from some applications. This patch adds a "warn once" wrapper macro, heavily inspired by src/mesa/drivers/dri/r600/radeon_debug.h Signed-off-by: Tormod Volden <debian.tormod@gmail.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
2009-09-21intel: Mark the FBO as incomplete if there's no intel_renderbuffer for it.Eric Anholt1-0/+5
This happens to rendering with textures with a border, which had resulted in a segfault on dereferencing the irb. (cherry-picked from commit 8bba183b9eeb162661a287bf2e118c6dd419dd24)
2009-09-21softpipe: Fix cube face selection.Brian Paul1-2/+2
If arx and ary are equal, we still want to choose from one of them, and not arz. (cherry picked from commit de685b37a91bc95dd4093a44a49b7b47385b1f7c)
2009-09-21swrast: fix cube face selectionBrian Paul1-2/+2
If arx and ary are equal, we still want to choose from one of them, and not arz. This is the same as Michal's softpipe fix.
2009-09-21intel: Fix crash in intel_flush().Michel Dänzer1-1/+2
Since commit 2921a2555d0a76fa649b23c31e3264bbc78b2ff5 ('intel: Deassociated drawables from private context struct in intelUnbindContext'), intel->driDrawable may be NULL in intel_flush().
2009-09-20mesa/st: Initialize format bits of framebuffer renderbuffersNicolai Hähnle1-0/+1

2009-09-16glx: Use initstate_r / random_r instead of corrupting global random number stateIan Romanick1-3/+7
Previously srandom and random were used. This cause the global random number generator state to be modified. This caused problems for applications that called srandom before calling into GLX. By using local state the global state is left unmodified. This should fix bug #23774.
2009-09-16st/mesa: fix some incorrect branching/clean-up code in TexImage functionsBrian Paul1-3/+3
We need to be sure to call the _mesa_unmap_teximage_pbo() function if we called _mesa_validate_pbo_teximage().
2009-09-16st/mesa: fix texture memory allocation bugBrian Paul1-2/+10
The following example caused an incorrect GL_OUT_OF_MEMORY error to be raised in glTexSubImage2D: glTexImage2D(level=0, width=32, height=32, pixels=NULL); glTexImage2D(level=0, width=64, height=64, pixels=NULL); glTexSubImage2D(level=0, pixels!=NULL); The second glTexImage2D() call needs to cause the first image to be deallocated then reallocated at the new size. This was not happening because we were testing for pixels==NULL too early.
2009-09-16intel: Deassociated drawables from private context struct in intelUnbindContextIan Romanick1-0/+8
The generic DRI infrastructure makes sure that __DRIcontextRec::driDrawablePriv and __DRIcontextRec::driReadablePriv are set to NULL after unbinding a context. However, the intel_context structure keeps cached copies of these pointers. If these cached pointers are not NULLed and the drawable is actually destroyed after unbinding the context (typically by way of glXDestroyWindow), freed memory will be dereferenced in intelDestroyContext. This should fix bug #23418.
2009-09-15mesa: compile glUniformMatrix() functions into display listsBrian Paul1-0/+242
I believe this is the last of the shader-related functions that needed display list treatment.
2009-09-15mesa: implement more glUniform display list functionsBrian Paul1-1/+365
2009-09-15mesa: compile glUniform4f() into display listsBrian Paul1-0/+26
Note: there are more glUniform functions to compile...
2009-09-15mesa: compile glUseProgram/glUseProgramObjectARB into display listsBrian Paul1-0/+28
Fixes bug 23746
2009-09-15GLX: Complain when buggy applications call GLX 1.3 functions.Ian Romanick1-0/+28
2009-09-14glsl: added some link debug code (disabled)Brian Paul1-0/+15
2009-09-14glsl: remove extra #version directives from concatenated shader sourcesBrian Paul1-0/+28
When we concatenate shaders to do our form of poor-man linking, if there's multiple #version directives, preprocessing fails. This change disables the extra #version directives by changing the first two chars to //. This should help with some Wine issues such as bug 23946.

2009-09-10softpipe: minor indentation fixBrian Paul1-1/+1
2009-09-10softpipe: set dirty_render_cache in softpipe_clear()Brian Paul1-0/+2
This fixes a bug seen when doing a glDrawPixels(GL_STENCIL_INDEX) right after a glClear(). The check-for-flush test was failing because we didn't set the dirty_render_cache flag in softpipe_clear(). So we saw stale data when we mapped the stencil buffer.
2009-09-10intel: add B43 chipset supportZhenyu Wang2-1/+6
Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Hopefully this will be one of the last cherry-picks. (cherry picked from commit ca246dd186f9590f6d67038832faceb522138c20)
2009-09-08mesa: bump version to 7.5.2Brian Paul1-3/+3
I'm not 100% sure there'll be a 7.5.2 release, but just in case.
2009-09-08i965: fix incorrect test for vertex position attributeBrian Paul3-1/+4

(cherry picked from commit df70d3049a396af3601d2a1747770635a74120bb)
2009-09-04intel: Update Mesa state before span setup in glReadPixels.Eric Anholt3-3/+13
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: Align untiled region height to 2 according to 965 docs.Eric Anholt1-0/+7
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 Anholt3-1/+5
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 Anholt1-1/+21
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: Emit conditional code updates as required for GLSL VS if statements.Eric Anholt1-0/+13
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 Anholt3-15/+15
2009-09-04i965: Fix RECT shadow sampling by not losing the other texcoords.Eric Anholt1-1/+5
Bug #20821 (cherry picked from commit 191e028de20b2f954621b652aa77b06d0e93652a)
2009-09-04i965: Assert that the offset in the VBO is below the VBO size.Eric Anholt1-0/+14
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 Anholt1-0/+11
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 Anholt1-1/+8
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 Anholt1-0/+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)
2009-09-04i965: Calculate enabled[] and nr_enabled once and re-use the values.Eric Anholt2-29/+18
The code duplication bothered me. (cherry picked from commit 9b9cb30d128fc5f1ba77287696ecd508e640efde)
