  "message": "D3D11: Use blocking waits for last submitted serial in DelayFlushQueue\n\nPreviously, D3D11\u0027s DelayFlushQueue relied on ID3D11Query for\ncommand buffer completion signals. While ID3D11Query is generally\nefficient, waiting for it often involved CPU-intensive spin-waiting,\nwhich could hinder the use of less powerful CPU cores. This update\nintroduces a minor but significant optimization: by utilizing a\nblocking Win32 event for the last submitted serial\u0027s wait, we\neliminate spin-waiting and improve overall CPU resource management.\n\nBug: chromium:430308396\nChange-Id: I3965e20b103d39b2bd8e464e14692dd1bc9a8a7c\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/251554\nCommit-Queue: Quyen Le \u003clehoangquyen@chromium.org\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\n",
