* i965/gen9: Implement Push Constant Buffer workaroundBen Widawsky2015-06-221-7/+41
| | | | | | | | | | | | | | | | | | | | | | | This implements a workaround (exact excerpt as a comment in the code). The docs specify [clearly, after you struggle for a while] that the offset isn't relative to state base. This actually makes sense. This fixes hangs on SKL. Buffer #0 is meant to be used for normal uniforms. Buffer #1 is typically used for gather constants when using RS. Buffer #1-#3 could be used to push a bunch of UBO data which would just be somewhere in memory, and not relative to the dynamic state. NOTE: I've moved away from the ternary operator for the new gen9 conditions. Admittedly it's probably not great to do this, but I really want to fix this all up in the subsequent patch and doing it here makes that diff a lot nicer. I want to split out the gen8/9 code to make the function a bit more readable, but to keep this easily cherry-pickable I am doing this fix first. If we decide not to merge the cleanup patch then I can revisit this.

* i965/gen8: Use HALIGN_16 for single sample mcs buffersBen Widawsky2015-06-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original code meant to do this, but was only checking num_samples == 1 to figure out if a surface was fast clear capable. However, we can allocate single sample miptrees with num_samples == 0 (when it's an internally created buffer). This fixes a bunch of the piglit tests on gen8. Other gens should have been fine. Here is the order of events that allowed this to slip through: t0: I wrote halign patches and tested them. These alignment assertions are for gen8 fast clear surfaces, basically. t1: I pushed bogus perf patch which made fast clears never happen t2: Reworked halign patches based on Chad's feedback and introduced the bug this patch fixes. t2.5: I tested reworked patches, but assertion wasn't hit because of t1. t3.

* i965: Fix textureGrad with cube samplersIago Toral Quiroga2015-06-181-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't use sampler messages with gradient information (like sample_g or sample_d) to deal with this scenario because according to the PRM: "The r coordinate and its gradients are required only for surface types that use the third coordinate. Usage of this message type on cube surfaces assumes that the u, v, and gradients have already been transformed onto the appropriate face, but still in [-1,+1] range. The r coordinate contains the faceid, and the r gradients are ignored by hardware." Instead, we should lower this to compute the LOD manually based on the gradients and use a different sample message that takes the computed LOD instead of the gradients. This is already being done in brw_lower_texture_gradients.cpp, but it is restricted to shadow samplers only, although there is a comment stating that we should probably do this also for samplerCube and samplerCubeArray. Because of this, both dEQP and Piglit test cases for textureGrad with cube maps currently fail. This patch does two things: 1) Activates the texturegrad lowering pass for all cube samplers. 2) Corrects the computation of the LOD value for cube samplers. I had to do 2) because for cube maps the calculations implemented in the lowering pass always compute a value of rho that is twice the value we want (so we get a LOD value one unit larger than we want). This only happens for cube map samplers (all kinds). I am not sure about why we need to do this, but I suspect that it is related to the fact that cube map coordinates, when transported to a specific face in the cube, are in the range [-1, 1] instead of [0, 1] so we probably need to divide the derivatives by 2 when we compute the LOD. Doing that would produce the same result as dividing the final rho computation by 2 (or removing a unit from the computed LOD, which is what we are doing here).

* i965/vec4: Fix the source register for indexed samplersNeil Roberts2015-06-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously when setting up the sample instruction for an indirect sampler the vec4 backend was directly passing the pseudo opcode's src0. However vec4_visitor::visit(ir_texture *) doesn't set the texture operation's src0 -- it's left as BAD_FILE, which when translated into a brw_reg gives the null register. In brw_SAMPLE, gen6_resolve_implied_move() inserts a MOV from the inst->base_mrf and sets the src0 appropriately. The indirect sampler case did not have a call to gen6_resolve_implied_move(). The fs backend avoids this because the platforms that support dynamic indexing of samplers (IVB+) have been converted to not use the fake-MRF hack, and instead send from proper GRFs. This patch makes it call gen6_resolve_implied_move before setting up the indirect message. This is similar to what is done for constant sampler numbers in brw_SAMPLE. The Piglit tests for sampler array indexing didn't pick this up because they were using a texture with a solid colour so it didn't matter what texture coordinates were actually used. The tests have now been changed to be more thorough in this commit: http://cgit.freedesktop.org/piglit/commit/?id=4f9caf084eda7 With that patch the tests for gs and vs are currently failing on Ivybridge, but this patch fixes them. There are no other changes to a Piglit run on Ivybridge. On Skylake the gs tests were failing even without the Piglit patch because Skylake needs the source registers to work correctly in order to send a message header to select SIMD4x2 mode.

| | | | | | | | | | | | | | | | | | This function was trying to align the width and height to a multiple of the block size for compressed textures. It was using align_w/h as a shortcut to get the block size as up until Gen9 this always happens to match. However in Gen9+ the alignment values are expressed as multiples of the block size so in effect the alignment values are always 4 for compressed textures as that is the minimum value we can pick. This happened to work for most compressed formats because the block size is also 4, but for FXT1 this was breaking because it has a block width of 8.
