This patch is mainly to support gstreamer-vaapi and tools that uses this newer libva API. The first advantage of using VaCreateSurfaces2 over existing VaCreateSurfaces, is that it is possible to select which the pixel format for the surface. Indeed with the simple VaCreateSurfaces function it is only possible to create a NV12 surface. It can be useful to create a RGBA surface to use with video post processing.

* i965/sched: use liveness analysis for computing register pressureConnor Abbott2015-10-301-56/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we were using some heuristics to try and detect when a write was about to begin a live range, or when a read was about to end a live range. We never used the liveness analysis information used by the register allocator, though, which meant that the scheduler's and the allocator's ideas of when a live range began and ended were different. Not only did this make our estimate of the register pressure benefit of scheduling an instruction wrong in some cases, but it was preventing us from knowing the actual register pressure when scheduling each instruction, which we want to have in order to switch to register pressure scheduling only when the register pressure is too high. This commit rewrites the register pressure tracking code to use the same model as our register allocator currently uses. We use the results of liveness analysis, as well as the compute_payload_ranges() function that we split out in the last commit. This means that we compute live ranges twice on each round through the register allocator, although we could speed it up by only recomputing the ranges and not the live in/live out sets after scheduling, since we only shuffle around instructions within a single basic block when we schedule. Shader-db results on bdw: total instructions in shared programs: 7130187 -> 7129880 (-0.00%) instructions in affected programs: 1744 -> 1437 (-17.60%) helped: 1 HURT: 1 total cycles in shared programs: 172535126 -> 172473226 (-0.04%) cycles in affected programs: 11338636 -> 11276736 (-0.55%) helped: 876 HURT: 873 LOST: 8 GAINED: 0 v2: use regs_read() in more places.

* i965: always run the post-RA schedulerConnor Abbott2015-10-301-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before, we would only do scheduling after register allocation if we spilled, despite the fact that the pre-RA scheduler was only supposed to be for register pressure and set the latencies of every instruction to 1. This meant that unless we spilled, which we rarely do, then we never considered instruction latencies at all, and we usually never bothered to try and hide texture fetch latency. Although a later commit removes the setting the latency to 1 part, we still want to always run the post-RA scheduler since it's able to take the false dependencies that the register allocator creates into account, and it can be more aggressive than the pre-RA scheduler since it doesn't have to worry about register pressure at all.

* i965: fix cycle estimates when there's a pipeline stallConnor Abbott2015-10-301-7/+8
| | | | | | | | | | | | The issue time for an instruction is how many cycles it takes to actually put it into the pipeline. If there's a pipeline stall that causes the instruction to be delayed, we should first take that into account to figure out when the instruction would start executing and *then* add the issue time. The old code had it backwards, and so we would underestimate the total time whenever we thought there would be a pipeline stall by up to the issue time of the instruction.

| | | | | | | | | | | | | | | | | This patch makes the visitor convert registers to the HW_REG file at the very end, after register allocation, post-RA scheduling, and dependency control flagging. After that, everything is in fixed brw_regs. This simplifies the code generator, as it can just use the hardware registers rather than having to interpret our abstract files. In particular, interpreting the UNIFORM file meant reading prog_data to figure out where push constants are supposed to start. Having the part of the code that performs register allocation also translate everything to hardware registers seems sensible.

* r600g: Fix special negative immediate constants when using ABS modifier.Ivan Kalvachev2015-10-293-6/+6
| | | | | | | | | | | | | | | | | | | | | Some constants (like 1.0 and 0.5) could be inlined as immediate inputs without using their literal value. The r600_bytecode_special_constants() function emulates the negative of these constants by using NEG modifier. However some shaders define -1.0 constant and want to use it as 1.0. They do so by using ABS modifier. But r600_bytecode_special_constants() set NEG in addition to ABS. Since NEG modifier have priority over ABS one, we get -|1.0| as result, instead of |1.0|. The patch simply prevents the additional switching of NEG when ABS is set.

* i965: Implement ARB_fragment_layer_viewport.Kenneth Graunke2015-10-284-1/+46
| | | | | | | | | | | | | | Normally, we could read gl_Layer from bits 26:16 of R0.0. However, the specification requires that bogus out-of-range 32-bit values written by previous stages need to appear in the fragment shader as-written. Instead, we pass in the full 32-bit value from the VUE header as an extra flat-shaded varying. We have the SF override the value to 0 when the previous stage didn't actually write a value (it's actually defined to return 0).
