1115: Request buffer FAST_DEVICE_ACCESS only with some non MAP or COPY usage r=kvark a=fintelia **Connections** Fixes #1113 **Description** On Linux AMD (and likely elsewhere) buffers with FAST_DEVICE_ACCESS are very slow to access when mapped. This makes sure that upload/download buffers don't request it unless those buffers are leveraging MAPPABLE_PRIMARY_BUFFERS for some non-map/copy usage. **Testing** I reran the failing reproduction case in the linked issue.

This is an active GitHub mirror of the WebGPU implementation in Rust, which now lives in "gfx/wgpu" of Mozilla-central. Issues and pull requests are accepted, but some bidirectional synchronization may be involved.
WebGPU
This is the core logic of an experimental WebGPU implementation. It's written in Rust and is based on gfx-hal with help of gpu-alloc and gpu-descriptor. See the upstream WebGPU specification (work in progress).
The implementation consists of the following parts:
- internal Rust API for WebGPU implementations to use
- Rust types shared between
wgpu-core,wgpu-native, andwgpu-rsplayer- standalone application for replaying the API traces, useswinit
This repository contains the core of wgpu, and is not usable directly by applications.
If you are looking for the user-facing Rust API, you need wgpu-rs.
If you are looking for the native implementation or bindings to the API in other languages, you need wgpu-native.
