Specificationhttps://github.com/gpuweb/gpuweb/pull/4331 Summary Functionality added to the WebGPU/WGSL spec after its first shipment in a browser. Loosens a restriction where using readonly depth-stencil attachments in a render pass required both aspects (depth and stencil) to be readonly. This was too strict, and prevent use-cases where for example the depth is used readonly for contact shadow tracing, while the stencil buffer is written to do identify pixels for further processing. (Both Unity and Unreal do things with mixed depth-stencil readonliness). Blink componentBlink>WebGPU <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EWebGPU> TAG reviewNone TAG review statusNot applicable Risks Interoperability and Compatibility Separate RODS has not yet been implemented in any browser, but has been approved by the GPU for the Web Community Group, with representatives from Chrome, Firefox, and Safari. *Gecko*: No signal ( https://github.com/mozilla/standards-positions/issues/953) *WebKit*: Positive ( https://github.com/WebKit/standards-positions/issues/294#issuecomment-1877411933) Note that this is a blanket approval from Safari for additions to the v1 WebGPU/WGSL spec. *Web developers*: Positive Requested by multiple developers including for ports of the Unity and Unreal engines to WebGPU. *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 at the moment, WebGPU currently does not ship on Android WebView. 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, ChromeOS, Mac, and Windows, since those platforms already support WebGPU. 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 <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?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. Note that tests are still being written, but the feature will not be launched until it is fully tested. Flag name on chrome://flagsNone Finch feature nameNone Non-finch justificationNone Requires code in //chrome?False Tracking bughttps://bugs.chromium.org/p/dawn/issues/detail?id=2146 Availability expectationFeature is available only in Chromium browsers for the near future, on the order of months. Other browsers intend to ship WebGPU support, but don't have specified timelines. Non-OSS dependencies Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function? No Estimated milestones No milestones specified Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
