with 55ffa64daf765b1229364518106a4124bd84b9a7, the six tests listed here began to pass. However, the following tests regressed: es3-cts.shaders.uniform_block.single_nested_struct.single_buffer_std140_instance_array es3-cts.shaders.uniform_block.single_nested_struct.single_buffer_shared_instance_array es3-cts.shaders.uniform_block.single_nested_struct.per_block_buffer_std140_instance_array es3-cts.shaders.uniform_block.single_nested_struct.per_block_buffer_shared_instance_array es3-cts.shaders.uniform_block.random.all_per_block_buffers.8 Sample output: piglit.es3-cts.shaders.uniform_block.random.all_per_block_buffers.8.bxtm64 (from piglit) Failing for the past 14 builds (Since Unstable#1700 ) Took 2.3 sec.

The thread scratch space is thread-local so using the full IA-coherent stateless surface index (255 since Gen8) is unnecessary and potentially expensive. On Gen8 and early steppings of Gen9 this is not a functional change because the kernel already sets bit 4 of HDC_CHICKEN0 which overrides all HDC memory access to be non-coherent in order to workaround a hardware bug. This happens to fix a full system hang when running any spilling code on a pre-production SKL GT4e machine I have on my desk (forcing all HDC access to non-coherent from the kernel up to stepping F0 might be a good idea though regardless of this patch), and improves performance of the OglPSBump2 SynMark benchmark run with INTEL_DEBUG=spill_fs by 33% (11 runs, 5% significance) on a production SKL GT2 (on which HDC IA-coherency is apparently functional so it wouldn't make sense to disable globally). Reviewed-by: Kristian Høgsberg <krh@bitplanet.net> piglit.spec.glsl-1_50.execution.variable-indexing.gs-output-array-vec4-index-wr also fails on BXT with this commit fixed by mesa 55ffa64daf765b1229364518106a4124bd84b9a7 and mesa 46c0ba60c606d7af5518918bb305cb493227dc18 |
