Jamie Madill 752d220a 2018-11-27T13:29:48 Use flat enum for PrimitiveMode. The GLenum was already mostly packed. There were just a few missing values because of the exclusion of things like GL_QUADS and GL_POLYGON from GLES. Also update the PackedEnumMap initialization to take an intializer. The initializer is a list of key/values which is much more robust to changes in the packed map. Improves draw call speed slightly as there is no conversion needed any more for the mode enum.

Jamie Madill f3acb8c1 2018-11-14T16:24:25 Retool perf test running. This change does a few things involving the way we run the perf tests: - Perf test runner can capture different metrics Useful for capturing the new "nanoSecPerIteration" metric. - Removes the "score" metric We'll move to the new time-based metrics. These new metrics are scaled correctly with iteration counts. - Runs three trials per perf test This gives more measurements per test. Each trial is approximately one second. First the perf tests set a fixed number of iterations after calibrating the number of steps that we can run in one second. After that the three trials are run. This should give more stable results. - Apply more CPU stabilization on Windows Use SetPriorityClass to apply more CPU priority. Also upgrade SetThreadPriority to the highest level. - Always build the Vulkan command buffer test This catches build regressions more easily. We still skip the test on non-Android platforms.

This test verifies the behavior when different stencil masks are set for front and back faces, which is unsupported in D3D and disallowed in WebGL.

Jamie Madill 3402d523 2018-10-30T15:14:52 Try to reduce variance in angle_perftests. This change does a few things: - make perf test runner script print % variation instead of stddev This makes it a bit more clear how much variance there is. - stabilize CPU in the render perf tests Setting a thread affinity and priority should stop from switching cores during the run. Hopefully can prevent background noise from changing the test results. - warm up the benchmark with a few iterations This should hopefully make the test results a bit more stable. - output a new normalized perf result value The new result is normalized against the number of iterations. So it should hopefully be stable even if the number of iterations is changed. - increases the iteration count in the draw call perf tests. These tests were completely dominated by SwapBuffers time. Increasing the iterations per step means we actually are bottlenecked on CPU time instead.

Jamie Madill 78bcd2be 2018-10-16T15:05:20 Vulkan: Fix deleting in-use descriptor sets. Sequences of many frames with uniform updates could lead to a bug where we attempt to delete descriptor sets that are still in use. To trigger the bug we need to write enough uniform data to trigger a descriptor set to be freed. This would correctly trigger refresh sets in the Program. But if there was a second program idle in the background that also allocated descriptors from the old pool, the bug would manifest. Fix this by storing a shared handle to the descriptor pool in the Program. The dynamic descriptor pool won't recycle descriptor pools internally unless there are zero outstanding references to the pool. We could also improve this in a resource sharing situation by keeping a single shared dynamic descriptor pool per share group. Includes a contribution from tobine@google.com that adds a test to cover the bug.

Qin Jiajia 1d8a783c 2018-10-09T13:59:56 Re-land: "ES31: Add vector and matrix support in SSBO for D3D" Re-land skips ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11 to pass the bots. In fact, ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11 is not a regression. The reverted CL added more SSBO features and triggered the failure. To enable ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11, we should support SSBO in render pipeline. This needs to bind SSBO to UAV registers in link time instead of compile time since output variables also occupies the UAVs. Let's enable this test when we support SSBO in render pipeline. Currently, we shouldn't block the SSBO implementation in some common features.

Add a callback function to the CompileProgram utility function to fulfill this need. This reduces code duplication considerably in several tests. An alternative way to improve CompileProgram would be to split it into several different utility functions. This might be slightly easier to read, but would also be a larger refactoring and require more checks at the call site. This will make it easier to implement EXT_blend_func_extended tests, which need to bind fragment outputs to different slots.
