New versions of several crates are introduced to third_party/rust, by changing the versions requested in `gfx/wgpu_bindings/Cargo.toml` and running `mach vendor rust`: - `wgpu-core`, `wgpu-hal`, and `wgpu-types`, as used by `wgpu_bindings` - `naga`, `ash`, and `metal`, as used by the above These are all exact copies of the upstream sources, at the git revisions listed in `.cargo/config.in`. This brings in fixes for some upstream `wgpu` bugs that were fuzzblockers: - Compute pipelines never freed at runtime, leaking memory #2564 https://github.com/gfx-rs/wgpu/issues/2564 - Device::drop doesn't actually free the device when using backend::direct::Context #2563 https://github.com/gfx-rs/wgpu/issues/2563 The Firefox sources also needed some adjustments to catch up with upstream changes: - The C type `mozilla::webgpu::ffi::WGPUTextureFormat` is now a struct containing a tag enum and a union, not just an enum. This is needed for [gfx-rs/wgpu#2477](https://github.com/gfx-rs/wgpu/pull/2477). (Note that Firefox's `WebGPU.webidl` is behind the current spec, so even though the newest ASTC texture formats are supported in `wgpu`, they're not available in Firefox yet.) - `wgpu` got a new feature, `id32`, which cbindgen needed to be told about so that it would generate preprocessor-protected code like this: #if defined(WGPU_FEATURE_ID32) typedef uint32_t WGPUNonZeroId; #endif #if !defined(WGPU_FEATURE_ID32) typedef uint64_t WGPUNonZeroId; #endif instead of just spitting out two conflicting definitions of `WGPUNonZeroId`. - The `wgpu_core::hub::IdentityHandlerFactory` trait's `spawn` method no longer takes a `min_index` argument. (Our implementations of that trait never used that argument anyway, so this was easy to accommodate.) Differential Revision: https://phabricator.services.mozilla.com/D142779 |
