Explainer It is important for libraries that take user-provided GPUDevice objects to access information about the physical GPU, as they may need to optimize or implement workarounds based on the GPU architecture. While it is possible to access this information through the GPUAdapter object, there is no direct way to get it from a GPUDevice alone. This can be inconvenient, as it may require users to provide additional information alongside the GPUDevice. To address this problem, we expose GPUAdapterInfo through the GPUDevice adapterInfo attribute. Those are similar to the existing GPUAdapter info attribute. https://github.com/gpuweb/gpuweb/pull/4809 Specification https://www.w3.org/TR/webgpu/#dom-gpudevice-adapterinfo Summary Functionality added to the WebGPU spec after its first shipment in a browser. The GPUDevice adapterInfo attribute exposes the same GPUAdapterInfo as the GPUAdapter object.. Blink component Blink>WebGPU <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EWebGPU> TAG review None TAG review status Not applicable Risks Interoperability and Compatibility This feature has not yet been implemented in any browser. It has been approved by the GPU for the Web Community Group, with representatives from Chrome, Firefox, and Safari. See minutes at https://docs.google.com/document/d/1FlVeiqRzx5t-9z03Ocx7_gw-lPpysUaw_83xofJyxQQ/edit and https://github.com/gpuweb/gpuweb/pull/4809 Gecko: No signal (Mozilla members have requested during weekly standardization meetings that we postpone filing standard positions until we reach Candidate Recommendation (CR) status in Q4.) WebKit: Positive ( https://github.com/WebKit/standards-positions/issues/294#issuecomment-1877411933 ) Web developers: Positive (https://github.com/gpuweb/gpuweb/issues/4810) 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 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, 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. 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. All the tests about this feature in WebGPU CTS can be found through the below link: https://github.com/gpuweb/cts/pull/4023 Flag name on chrome://flags chrome://flags/#enable-unsafe-webgpu Finch feature name WebGPUDeviceAdapterInfo Requires code in //chrome? False Tracking bug https://issues.chromium.org/issues/376600838 Estimated milestones DevTrial on desktop 132 DevTrial on Android 132 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).
