| | | | | | | | | | | This is actually required for GL_ARB_framebuffer_object, but the state tracker doesn't currently check it. Direct3D 9 allows mixed format color buffers with some restrictions. Setting this allows Unigine Heaven 2.5 and 3.0 to run. Tested both on GL and D3D hosts. Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Jakob Bornecrantz <[email protected]>

* i965/msaa: Set KILL_ENABLE when GL_ALPHA_TO_COVERAGE enabled.Paul Berry2012-06-262-4/+6
| | | | | | | | | | | | | | | i965 hardware needs to be informed of situations in which it's possible for pixels (or samples) to be discarded for reasons other than depth/stencil testing (e.g. due to an explicit "discard" in the fragment shader). One of these situations is when GL_ALPHA_TO_COVERAGE is enabled, since that can cause samples to be discarded by the color calculator when the pixel's alpha value is less than 1.0. Without this patch, GL_ALPHA_TO_COVERAGE does not take effect on depth buffers. Reviewed-by: Anuj Phogat <[email protected]>
* i965/msaa: Implement GL_SAMPLE_ALPHA_TO_{COVERAGE,ONE}.Paul Berry2012-06-261-1/+9
| | | | | | | | | | | | | | | | | | | | | | This patch enables the multisampling parameters GL_SAMPLE_ALPHA_TO_COVERAGE and GL_SAMPLE_ALPHA_TO_ONE, which allow the fragment shader's alpha output to be converted into a sample coverage mask and ignored for blending. i965 supports these parameters through the BLEND_STATE structure. The GL spec allows, but does not require, the implementation to dither the conversion from alpha to a sample coverage mask, so that alpha values that aren't a multiple of 1/num_samples result in the correct proportion of samples being lit. A bit exists in the BLEND_STATE structure to enable this functionality, but according to the hardware docs it must be disabled on Sandy Bridge (see the Sandy Bridge PRM, Vol2, Part1, p379: AlphaToCoverage Dither Enable). So it is enabled for Gen7 only. Fixes piglit tests "EXT_framebuffer_multisample/sample-alpha-to-{coverage,one} {2,4}". Reviewed-by: Anuj Phogat <[email protected]>
* i965/msaa: Implement glSampleCoverage.Paul Berry2012-06-264-7/+26
| | | | | | | | | | | | | | This patch enables glSampleCoverage() functionality, which allows the client program to specify that only a portion of the samples be lit up when performing multisampled rendering. i965 supports glSampleCoverage() through the 3DSTATE_SAMPLE_MASK command packet, which allows the driver to specify a bitfield indicating which samples to light up.

* i965/fs: Fix conversions float->bool, int->boolChad Versace2012-06-251-7/+7
| | | | | | | | | | | | | | | | | Fixes gles2conform GL.equal.equal_bvec2_frag. This fixes brw_fs_visitor's translation of ir_unop_f2b. It used CMP to convert the float to one of 0 or ~0. However, the convention in the compiler is that true is represented by 1, not ~0. This patch adds an AND to convert ~0 to 1. By inspection, a similar problem existed with ir_unop_i2b, with a similar fix. [v2 kayden]: eliminate extra temporary register.

* i965/msaa: Add backend support for centroid interpolation.Paul Berry2012-06-253-11/+32
| | | | | | | | | | | | | | | This patch causes the fragment shader to be configured correctly (and the correct code to be generated) for centroid interpolation. This required two changes: brw_compute_barycentric_interp_modes() needs to determine when centroid barycentric coordinates need to be included in the pixel shader thread payload, and fs_visitor::emit_general_interpolation() needs to interpolate using the correct set of barycentric coordinates.

* i965/msaa: Adapt clip setup for centroid noperspective interpolation.Paul Berry2012-06-253-2/+6
| | | | | | | | | | | | | | | | | | To save time, we only instruct the clip stage of the pipeline to compute noperspective barycentric coordinates if those coordinates are needed by the fragment shader. Previously, we would determine whether the coordinates were needed by seeing whether the fragment shader used the BRW_WM_NONPERSPECTIVE_PIXEL_BARYCENTRIC interpolation mode. However, with MSAA, it's possible that the fragment shader might use BRW_WM_NONPERSPECTIVE_CENTROID_BARYCENTRIC instead. In the future, when we support ARB_sample_shading, it might use BRW_WM_NONPERSPECTIVE_SAMPLE_BARYCENTRIC. This patch modifies the upload_clip_state() functions to check for all three possible noperspective interpolation modes. Reviewed-by: Eric Anholt <[email protected]>

* 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.
