Add performance tests for WebGL draw call submission
https://bugs.webkit.org/show_bug.cgi?id=321788
Reviewed by Kimmo Kinnunen.
Added two microbenchmarks for WebGL draw call submission.
- WebGL-drawArrays.html measures the throughput of bare drawArrays calls
drawing a small triangle, with the GPU process is dominated by the per-message
cost of the RemoteGraphicsContextGL stream.
- WebGL-drawArrays-parallel.html measures whether submitted draw calls execute
in parallel with script running after their submission: it scales a fragment
shader so a group of draws takes roughly 10 ms of GPU time, then submits the
draws, busy-waits in script for the same time and finishes. A run costs
about one target duration when draw execution overlaps the script, and about
two when the draws only start at the sync point.
