* Make wgpu-core's copy_buffer_to_buffer `size` parameter optional * Make the copy size optional in more places * Fix for webgpu backend * [deno_webgpu] Support additional copyBufferToBuffer signatures * Add changelog entry * Add copyBufferToBuffer tests to CTS test list (This doesn't actually enable the tests for the new overloads, because of a different error reporting issue that affects many CTS tests including these. But if you run the tests for the new overloads manually, before and after the fix, you can see that the behavior has changed.) * Reproducible formula for vendoring modified webgpu-sys Commit the updated vendor command in all the files for consistency.
deno_webgpu
This op crate implements the WebGPU API as defined in https://gpuweb.github.io/gpuweb/ in Deno. The implementation targets the spec draft as of March 31, 2024. The spec is still very much in flux. This extension tries to stay up to date with the spec, but is constrained by the features implemented in our GPU backend library wgpu.
The spec is still very bare bones, and is still missing many details. As the spec becomes more concrete, we will implement to follow the spec more closely.
In addition, setting the DENO_WEBGPU_TRACE environmental variable will output
a
wgpu trace
to the specified directory.
For testing this op crate will make use of the WebGPU conformance tests suite, running through our WPT runner. This will be used to validate implementation conformance.
GitHub CI doesn't run with GPUs, so testing relies on software like DX WARP & Vulkan lavapipe. Currently, only using DX WARP works, so tests are only run on Windows.
