* st/va: properly defines VAImageFormat formats and improve VaCreateImageJulien Isorce2015-10-303-11/+57
| | | | | | | | | | | | | | | | | Added PIPE_VIDEO_CHROMA_FORMAT_NONE in p_format.h and return it by default in ChromaToPipe. Renamed YCbCrToPipe to VaFourccToPipeFormat because it now contains RGB. Implemented PipeFormatToVaFourcc which will be used later in VlVaDeriveImage. Note that gstreamer-vaapi check all the VAImageFormat fields.

* 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: Fix missing BRW_NEW_*_PROG_DATA flagging caused by cache reuse.Kenneth Graunke2015-10-282-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider the case of two nearly identical GLSL fragment shaders: out vec4 color; void main() { color = vec4(1); } and layout(early_fragment_tests) in; out vec4 color; void main() { color = vec4(1); } These shaders compile to the exact same assembly, but have distinct values for brw_wm_prog_data::early_fragment_tests. Since these are two independent GLSL shaders, they have different program keys - notably, brw_wm_prog_key::program_string_id differs. When uploading the second, brw_upload_cache will find an existing copy of the assembly in the cache BO, which means matching_data will be non-NULL. Although we create a second cache item (with the new key and prog_data), we set item->offset to the existing copy and avoid re-uploading duplicate assembly. However, brw_search_cache() would only flag BRW_NEW_*_PROG_DATA if item->offset differed from the supplied offset. With reuse, both programs have the same offset, but prog_data changed. We have to flag it, but failed to. To fix this, we simply need to check if the aux (prog_data) pointer changed. If either the assembly or the prog_data differs, flag it. This fixes a regression since 1bba29ed403e735ba0bf04ed8aa2e571884f, where Topi fixed brw_upload_cache() to actually reuse identical assembly. Prior to that, reuse basically never happened due to bugs. Unfortunately, this code apparently wasn't prepared to handle reuse! Fixes GPU hangs in Dolphin on Broadwell. Huge thanks to Pierre Bourdon and Ilia Mirkin for debugging this and helping track down the real issue.
