* 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/gen9: Disable Mip Tail for YF/YS tiled surfacesAnuj Phogat2015-06-162-2/+11
| | | | | | | | | | | | | | | Disabling miptails fixed the buffer corruption happening in FBO which use YF/YS tiled renderbuffer or texture as color attachment. Spec recommends disabling mip tails only for non-mip-mapped surfaces. But, without disabling miptails I couldn't get correct data out of mipmapped YF/YS tiled surface. We need better understanding of miptails before start using them. For now this patch helps move things forward.

* 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.

I didn't check, but perhaps this would work with blorp, however, meta clears allocate the miptree structure (which AFAICT needs the alignment also) way before it allocates using meta clears where the renderbuffer is allocated way before the aux buffer. The restriction is referenced in a few places, but the most concise one [IMO] from the spec is for Gen9. Gen8 loosens the restriction in that it only requires this for non-msrt surface. When Auxiliary Surface Mode is set to AUX_CCS_D or AUX_CCS_E, HALIGN 16 must be used.

* i965: Extract tiling from fast clear decisionBen Widawsky2015-06-122-16/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several constraints when determining if one can fast clear a surface. Some of these are alignment, pixel density, tiling formats, and others that vary by generation. The helper function which exists today does a suitable job, however it conflates "BO properties" with "Miptree properties" when using tiling. I consider the former to be attributes of the physical surface, things which are determined through BO allocation, and the latter being attributes which are derived from the API, and having nothing to do with the underlying surface. Determining tiling properties and creating miptrees are related operations (when we allocate a BO for a miptree) with some disjoint constraints. By extracting the decisions into two distinct choices (tiling vs. miptree properties), we gain flexibility throughout the code to make determinations about when we can or cannot fast clear strictly on the miptree. To signify this change, I've also renamed the function to indicate it is a distinction made on the miptree. I am torn as to whether or not it was a good idea to remove "non_msrt" since it's a really nice thing for grep. v2: Reword some comments (Chad) intel_is_non_msrt_mcs_tile_supported->intel_tiling_supports_non_msrt_mcs (Chad) Make full if ladder for gens in above function (Chad) Signed-off-by: Ben Widawsky <[email protected]> Cc: Topi Pohjolainen <[email protected]> Reviewed-by: Jordan Justen <[email protected]> Reviewed-by: Anuj Phogat <[email protected]> Reviewed-by: Chad Versace <[email protected]>

* i965: Consolidate certain miptree params to flagsBen Widawsky2015-06-129-75/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I think pretty much everyone agrees that having more than a single bool as a function argument is bordering on a bad idea. What sucks about the current code is in several instances it's necessary to propagate these boolean selections down to lower layers of the code. This requires plumbing (mechanical, but still churn) pretty much all of the miptree functions each time. By introducing the flags paramater, it is possible to add miptree constraints very easily. The use of this, as is already the case, is sometimes we have some information at the time we create the miptree that needs to be known all the way at the lowest levels of the create/allocation, disable_aux_buffers is currently one such example. There will be another example coming up in a few patches. v2: Tab fix.
