  "message": "[dawn][native] Don\u0027t handle availability in timestamp quantization shader\n\nThe timestamp quantization shader was used both to quantize, normalize\n(to ns values) and zero-out timestamps in the query resolve buffer. The\nzeroing-out was redundant because all backends either have guarantees\nfrom the target API that the queries not available are 0, or have special\nhandling in the backend to zero-out unavailable queries already.\n\nRemove that logic to simplify things a bit. This also allows removing\nTimestampParams::first. The dispatch for the quantization is also\nupdated to be sized for exactly the number of queries that are resolved\ninstead of running on the whole buffer.\n\nBug: 499140183\nChange-Id: I9b53b595c406d7e3fe05f1405010d64428d133f5\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/305055\nReviewed-by: Brandon Jones \u003cbajones@chromium.org\u003e\nReviewed-by: Kai Ninomiya \u003ckainino@chromium.org\u003e\nCommit-Queue: Corentin Wallez \u003ccwallez@chromium.org\u003e\n",
