* mesa: validate sampler uniforms during gluniform callsTapani Pälli2014-10-204-35/+36
| | | | | | | | | | | | | | | | | Patch fixes 'glsl-2types-of-textures-on-same-unit' in WebGL conformance test suite. No Piglit regressions, fixes gl-2.0-active-sampler-conflict. To avoid adding potentially heavy check during draw (valid_to_render), check is done during uniform updates by inspecting TexturesUsed mask. A new boolean variable is introduced to cache validation state. v2: take into account case where 2 uniforms use same unit (curro) also do the check only when SSO is not in use, SSO has own path for sampler validation.

* mesa: Add usage history bitfield to buffer objectsChris Forbes2014-10-161-0/+9
| | | | | | | | | | | | | | | | | | | | | | In the drivers, we occasionally want to reallocate the backing store for a buffer object; often to avoid waiting for the GPU to be finished with the previous contents. At the point that happens, we don't have a good way of determining where else the buffer object may be bound, and so no good way of determining which dirty flags need to be raised -- it's fairly expensive to go looking at all the possible binding points. Until now, we've considered any BO to be possibly bound as a UBO or TexBO, and flagged all that state to be reemitted. Instead, remember what kinds of binding point this buffer has ever been used with, so that the drivers can flag only what they need. I don't expect these bits to ever be reset, but that doesn't matter for reasonable apps. Signed-off-by: Chris Forbes <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>

Now, we have a single method, emit_texture(), that takes all the information needed to make a texture instruction and handles all the setup, and all we have to do to emit a texture instruction while converting from GLSL IR, Mesa IR, or any new backend is to extract the information emit_texture() needs and then call it. v2: Significant rebasing (by Ken).

* i965: Allow CSE on Gen4-5 unary math.Kenneth Graunke2014-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Due to the implicit move-from-GRF, unary math looks a lot like the Gen6+ math instruction: it's a single instruction (SEND) with a GRF source. The difference is that it also implicitly clobbers a message register. The only visible effect is that CSE will remove the MRF-clobbering from later math operations. This should be fine; compute_to_mrf and remove_redundant_mrf_writes don't look at the values populated by implied writes, so they can't rely on those values being present. Less interference may actually help those passes make more progress. Binary math is still problematic, since it involves a separate MOV instruction to load the second operand. We continue disallowing CSE for binary math operations. total instructions in shared programs: 3340303 -> 3340100 (-0.01%) instructions in affected programs: 26927 -> 26724 (-0.75%) Nothing hurt, gained, or lost. ~6% reduction on a few shaders.

| | | | | | | | | | | | | | | | | | | | There's no reason to stall on pwrite - the CPU always appends to the buffer and never modifies existing contents, and the GPU never writes it. Further, the CPU always appends new data before submitting a batch that requires it. This code predates the unsynchronized mapping feature, so we simply didn't have the option when it was written. Ideally, we would do this for non-LLC platforms too, but unsynchronized mapping support only exists for LLC systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Write-back caching cannot be used for buffers being scanned out by the display engine; surfaces used for scan-out must be write-through or uncached. I originally chose WT for render targets because it works in all cases. However, we really want to use write-back caching where possible, as it is more efficient. Most renderbuffers are not used for scanout - off-screen FBOs certainly are fine, and non-pageflipped backbuffers should be fine as well. So in most cases WB will work. However, we don't know what will be used for scan-out, so we instead simply use the PTE value specified by the kernel, as it knows these things. This matches our MOCS choice on Haswell.
