* clover: Add --with-clang-libdir option and verify CLANG_RESOURCE_DIRTom Stellard2012-06-222-1/+18
| | | | | | | | | | | | | | $CLANG_RESOURCE_DIR is the directory that contains all resources needed by clang to compile programs. When clover uses clang to compile kernels it needs to specify a resource dir, so that clang can find its internal headers (e.g. stddef.h). clang defines $CLANG_RESOURCE_DIR as $CLANG_LIBDIR/clang/$CLANG_VERSION This patch adds the --with-clang-libdir option in order to accommodate clang intalls to non-standard locations, and it also adds a check to the configure script to verify that $CLANG_RESOURCE_DIR/include contains the necessary header files.
* i965: Compute dFdy() correctly for FBOs.Paul Berry2012-06-226-9/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i965, dFdx() and dFdy() are computed by taking advantage of the fact that each consecutive set of 4 pixels dispatched to the fragment shader always constitutes a contiguous 2x2 block of pixels in a fixed arrangement known as a "sub-span". So we calculate dFdx() by taking the difference between the values computed for the left and right halves of the sub-span, and we calculate dFdy() by taking the difference between the values computed for the top and bottom halves of the sub-span. However, there's a subtlety when FBOs are in use: since FBOs use a coordinate system where the origin is at the upper left, and window system framebuffers use a coordinate system where the origin is at the lower left, the computation of dFdy() needs to be negated for FBOs. This patch modifies the fragment shader back-ends to negate the value of dFdy() when an FBO is in use. It also modifies the code that populates the program key (brw_wm_populate_key() and brw_fs_precompile()) so that they always record in the program key whether we are rendering to an FBO or to a window system framebuffer; this ensures that the fragment shader will get recompiled when switching between FBO and non-FBO use. This will result in unnecessary recompiles of fragment shaders that don't use dFdy(). To fix that, we will need to adapt the GLSL and NV_fragment_program front-ends to record whether or not a given shader uses dFdy(). I plan to implement this in a future patch series; I've left FIXME comments in the code as a reminder. Fixes Piglit test "fbo-deriv". NOTE: This is a candidate for stable release branches.

* radeon/llvm: Use the VLIW Scheduler for R600->NITom Stellard2012-06-2112-8/+75
| | | | | | | | | | | | | | | | | | | It's not optimal, but it's better than the register pressure scheduler that was previously being used. The VLIW scheduler currently ignores all the complicated instruction groups restrictions and just tries to fill the instruction groups with as many instructions as possible. Though, it does know enough not to put two trans only instructions in the same group. We are able to ignore the instruction group restrictions in the LLVM backend, because the finalizer in r600_asm.c will fix any illegal instruction groups the backend generates. Enabling the VLIW scheduler improved the run time for a sha1 compute shader by about 50%. I'm not sure what the impact will be for graphics shaders. I tested Lightsmark with the VLIW scheduler enabled and the framerate was about the same, but it might help apps that use really big shaders.

* dricore: Turn it into a normal library.Eric Anholt2012-06-214-28/+11
| | | | | | | | | | | | Our intention is still that it's not abi stable, so make the package version number get included in the library name. Now you can parallel install dricore-using drivers from multiple mesa versions. We can put it into lib now that we're following library versioning rules (assuming that ABIs don't change within a single Mesa point release). LD_LIBRARY_PATH still doesn't work with a non-/, non-/usr prefix because libtool uses rpath instead of runpath for nonstandard prefixes.

Instead, just bump the minor version and drop the patchlevel.

* st/mesa: fix transform feedback of unsubscripted gl_ClipDistance arrayMarcin Slusarz2012-06-202-44/+6
| | | | | | | | | | | | | | | | | | | | | | | | | gl_ClipDistance needs special treatment in form of lowering pass which transforms gl_ClipDistance representation from float[] to vec4[]. There are 2 implementations - at glsl linker level (enabled by LowerClipDistance option) and at glsl_to_tgsi level (enabled unconditionally for gallium drivers). Second implementation is incomplete - it does not take into account transform feedback (see commit 642e5b413e0890b2070ba78fde42db381eaf02e5 "mesa: Fix transform feedback of unsubscripted gl_ClipDistance array" for details). There are 2 possible fixes: - adding transform feedback support into glsl_to_tgsi version - ripping gl_ClipDistance support from glsl_to_tgsi and enabling gl_ClipDistance lowering on glsl linker side This patch implements 2nd option. All it does is: - reverts most of the commit 59be691638200797583bce39a83f641d30d97492 "st/mesa: add support for gl_ClipDistance" - changes LowerClipDistance to true Fixes Piglit tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{2,3,4,5,6,7,8}]-no-subscript" at least on nv50 and evergreen cards.

* i965/msaa: Only do multisample rasterization if GL_MULTISAMPLE enabled.Paul Berry2012-06-204-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | From the GL 3.0 spec (p.116): "Multisample rasterization is enabled or disabled by calling Enable or Disable with the symbolic constant MULTISAMPLE." Elsewhere in the spec, where multisample rasterization is described (sections 3.4.3, 3.5.4, and 3.6.6), the following text is consistently used: "If MULTISAMPLE is enabled, and the value of SAMPLE_BUFFERS is one, then..." So, in other words, disabling GL_MULTISAMPLE should prevent multisample rasterization from occurring, even if the draw framebuffer is multisampled. This patch implements that behaviour by setting the WM and SF stage's "multisample rasterization mode" to MSRAST_ON_PATTERN only when the draw framebuffer is multisampled *and* GL_MULTISAMPLE is enabled.

| | | | | | | | | | | | | | | | | | | | | | | Due to hardware limitations, MSAA is unsupported on Gen6 for formats containing >64 bits of data per pixel. From the Sandy Bridge PRM, vol4 part1, p72 ("Surface Format"): If Number of Multisamples is set to a value other than MULTISAMPLECOUNT_1, this field cannot be set to the following formats: - any format with greater than 64 bits per element - any compressed texture format (BC*) - any YCRCB* format Gen7 has a similar, but less stringent limitation: formats with >64 bits of data per pixel only support 4x MSAA. This patch causes the unsupported formats to report GL_FRAMEBUFFER_UNSUPPORTED. Fixes piglit "multisample-formats" tests on Gen6. Acked-by: Kenneth Graunke <[email protected]>
