Explainer None Specification https://github.com/gpuweb/gpuweb/commit/b39d86d356eb759d7564bc7c808ca62fce8bbf3e Summary Adds an optional field to WebGPU texture view creation to request a subset of the usage flags from the source texture. By default, texture view usage inherits from the source texture but there are view formats which can be incompatible with the full set of inherited usages. Adding a usage field to texture view creation allows the user request a subset of the source texture's usages that are valid with the view format and specific to their intended usage of the texture view. WebGPU implementations can also optimize the creation of low level resources and improve performance when using views with more specialized usage flags. Blink component Blink>WebGPU TAG review None TAG review status Not applicable Risks Interoperability and Compatibility This feature has been approved in W3C GPU for the Web WG meetings including participants from Safari and Firefox: https://github.com/gpuweb/gpuweb/wiki/GPU-Web-2024-07-24#createtexture-does-not-validate-viewformats-against-usage-4426 Gecko: No signal WebKit: Closed Without a Position (https://github.com/WebKit/standards-positions/issues/294#issuecomment-1877411933) Web developers: No signals Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Goals for experimentation Ongoing technical constraints None Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No All platforms will eventually have support. Will immediately be available on Android, Android WebView, ChromeOS, Mac, and Windows, where hardware support is available. Linux is planned to have WebGPU support in the future, so this feature will become available when WebGPU does. Is this feature fully tested by web-platform-tests? Yes WebGPU/WGSL have a conformance test suite (https://github.com/gpuweb/cts) that is regularly pulled into Chromium and part of the testing of Dawn/Tint in Chromium. While the CTS can be embedded in WPT, the WebGPU team opted to keep it separate in Chromium testing to use a customized harness for robustness and performance. Tests were added in this PR: https://github.com/gpuweb/cts/commit/1746bcbc10a809cbadb3b131675b885ed08d9da5 Flag name on chrome://flags None Finch feature name WebGPU.Enabled:UnsafeFeatures Requires code in //chrome?
