  "message": "Require MapWrite on SBM when creating buffer with mappedAtCreation \u003d true\n\nThis patch adds a validation that require the shared buffer memory\nmust have `MapWrite` usage when we create a buffer on it with\n`mappedAtCreation \u003d\u003d true` because to support such case we need to\ncreate staging buffer and do multiple copies, which adds extra\ncomplexity and currently we have no plan to support.\n\nBug: 386255678\nChange-Id: Ic10693d7079274d226fcb388b1ecb660ad8e027d\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/322215\nCommit-Queue: Shao, Jiawei \u003cjiawei.shao@intel.com\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\n",
