* gallium: Create a new PIPE_CAP_TILE_RASTER_ORDER for vc4.Eric Anholt2017-10-101-0/+3
| | | | | | | | | | | | | | | | Because vc4 can control the order that tiles are rasterized in, we can use it to implement overlapping blits using normal drawing and GL_ARB_texture_barrier, as long as we can tell the kernel what order to render the tiles in. This commit introduces the core gallium support, vc4 changes will follow. v2: Fix on the simulator. v3: Add the cap (disabled) to other drivers, add rst docs for the cap. v4: Rebase on PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS v5: Drop vc4 changes from this commit, for clarity.

| | | | | | | | | | The operation performed is all the same as LODQ, but with the usual differences between dx10 and GL texture opcodes, that is separate resource and sampler indices (plus result swizzling, and setting z/w channels to zero).

* tgsi: clarify the semantics of DFRACEXPNicolai Hähnle2017-09-291-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The status quo is quite the mess: 1. tgsi_exec will do a per-channel computation, and store the dst[0] result (significand) correctly for each channel. The dst[1] result (exponent) will be written to the first bit set in the writemask. So per-component calculation only works partially. 2. r600 will only do a single computation. It will replicate the exponent but not the significand. 3. The docs pretend that there's per-component calculation, but even get dst[0] and dst[1] confused. 4. Luckily, st_glsl_to_tgsi only ever emits single-component instructions, and kind-of assumes that everything is replicated, generating this for the dvec4 case: DFRACEXP TEMP[0].xy, TEMP[1].x, CONST[0][0].xyxy DFRACEXP TEMP[0].zw, TEMP[1].y, CONST[0][0].zwzw DFRACEXP TEMP[2].xy, TEMP[1].z, CONST[0][1].xyxy DFRACEXP TEMP[2].zw, TEMP[1].w, CONST[0][1].zwzw Settle on the simplest behavior, which is single-component calculation with replication, document it, and adjust tgsi_exec and r600.

| | | | | | | | | Sourcing the exponent for the zw destination pair from Z is consistent with both tgsi_exec and gallivm. In practice, st_glsl_to_tgsi always generates per-channel instructions anyway. Reviewed-by: Marek Olšák <[email protected]> Tested-by: Dieter Nützel <[email protected]>

| | | | | | | | | | | | | | | | | To be able to properly distinguish between GL_ANY_SAMPLES_PASSED and GL_ANY_SAMPLES_PASSED_CONSERVATIVE. This patch goes through all drivers, having them treat the two query types identically, except: 1. radeon incorrectly enabled conservative mode on PIPE_QUERY_OCCLUSION_PREDICATE. We now do it correctly, only on PIPE_QUERY_OCCLUSION_PREDICATE_CONSERVATIVE. 2. st/mesa uses the new query type.
