* i965: Move loop over texture units into brw_populate_sampler_prog_key.Kenneth Graunke2012-07-123-82/+81
| | | | | | | | | | | The whole reason I avoided this was because it might operate on a brw_vertex_program or a brw_fragment_program. However, that isn't a problem: all we need is the gl_program base type. This avoids awkwardly passing the loop counter 'i' as a parameter, simplifies both callers, and also plumbs prog in place for future use. Signed-off-by: Kenneth Graunke <[email protected]>
* i965: Always emit alpha when nr_color_buffers == 0.Kenneth Graunke2012-07-123-11/+6
| | | | | | | | | | | | | | | If alpha-testing is enabled, we need to send alpha down the pipeline even if nr_color_buffers == 0. However, tracking whether alpha-testing is enabled in the WM program key is expensive: it causes us to compile multiple specializations of the same shader, using program cache space. This patch removes the check for alpha-testing, and simply emits alpha whenever nr_color_buffers == 0. We believe this will also be necessary for alpha-to-coverage, and it should add minimal overhead to an uncommon case. Saving the recompiles should more than make up the difference.

* mesa: Require current libxcb.Eric Anholt2012-07-125-53/+2
| | | | | | | | | | Without that, people with buggy apps that looked at just the server string for GLX_ARB_create_context would call this function that just threw an error when you tried to make a context.

* radeon/llvm: Don't use lp_build_swizzle_aos() for swizzlesTom Stellard2012-07-121-8/+13
| | | | | | | This function assumes that lp_build_context::type is a vector type, which is not true for r600 or radeonsi. This fixes an assertion failure using glamor 2D accel.
* radeonsi: Dump TGSI code prior to doing TGSI->LLVM conversion.Tom Stellard2012-07-121-1/+6
| | | | | This way if the conversion fails, we know what the TGSI shader looks like.
* i965: Delete previous workaround for textureGrad with shadow samplers.Kenneth Graunke2012-07-124-75/+5
| | | | | | | | | | | | | | | It had many problems: - The shadow comparison was done post-filtering. - It required state-dependent recompiles whenever the comparison function changed. - It didn't even work: many cases hit assertion failures. - I never implemented it for the VS. The new lowering pass which converts textureGrad to textureLod by computing the LOD value works much better.

* i965: Add a lowering pass to convert TXD to TXL by computing the LOD.Kenneth Graunke2012-07-124-0/+157
| | | | | | | | | | | | | | | | | | Intel hardware doesn't natively support textureGrad with shadow comparisons. So we need to generate code to handle it somehow. Based on the equations of page 205 of the OpenGL 3.0 specification, it's possible to compute the LOD value that would be selected given the gradient values. Then, we can simply convert the TXD to a TXL. Currently, this passes 34/46 of oglconform's shadow-grad subtests; four cubemap tests are regressed. We should investigate this in the future. v2: Apply abs() to the scalar case (thanks to Eric). Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | I ran into this while trying to create a TXS query, which doesn't have a coordinate. Since it didn't get initialized to NULL, a bunch of visitors tried to access it and crashed.

* i965/msaa: Add CMS support to blorp.Paul Berry2012-07-111-2/+43
| | | | | | | | | | | | | | | | | | This patch updates the blorp engine to properly handle the case where the surface being textured from uses Gen7's CMS MSAA layout. The following changes were necessary: - Before reading color values from the surface, we need to read from the MCS buffer using the ld_mcs sampler message. This is done by the mcs_fetch() function, and the result is stored in the mcs_data register. This only needs to be done once per pixel, since the MCS value is shared between all samples belonging to a pixel. - When reading color values from the surface, we need to use the ld2dms sampler message instead of the ld2dss message, and we need to provide the value read from the MCS buffer as an argument.
