BufferUploadPerf

Tests repetitively uploading data to the GPU using either SetSubData or CreateBufferMapped.

Test Harness

The test harness provides a DawnPerfTestBase which Derived tests should inherit from. The harness calls Step() of a Derived class to measure its execution time. First, a calibration step is run which determines the number of times to call Step() to last approximately kCalibrationRunTimeSeconds. Then, Step() is called for the computed number of times, or until kMaximumRunTimeSeconds is exceeded. kNumTrials are performed and the results and averages per iteration* are printed. (See DawnPerfTest.h for the values of the constants).

The results are printed according to the format specified at [chromium]//build/scripts/slave/performance_log_processor.py

*The number of iterations a test performs should be passed to the constructor of DawnPerfTestBase. The reported times are the total time divided by numSteps * iterationsPerStep.
