CMake-only fork of https://dawn.googlesource.com/dawn with cleaned, vendored dependencies
69e1c4b638
Since https://dawn-review.googlesource.com/c/dawn/+/120940, callbacks will be deferred to be executed in next device.APITick() instead of immediately. However, if the device is already destroyed (last ref dropped), user/wire_server has no chance to call device.APITick() anymore, leading to the callbacks waiting in queue forever. This is also possibly the cause of memory leaks in cluserfuzz tests. This CL attempt to fix it by implementing Instance::ProcessEvents(): In this method, every created device will invoke APITick() even if it is already lost/externally released. bug: chromium:1422507 bug: dawn:752 Change-Id: Iec69ad3b547a7e88c6e1a2225b13ad060a501a4f Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/123420 Commit-Queue: Quyen Le <lehoangquyen@chromium.org> Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Austin Eng <enga@chromium.org> |

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
