This reverts commit b04a92f01be0e7dc2faf91e0f6f974f990e8b2f2. Reason for revert: Build failed on win-archive-dbg; see: https://chromium-review.googlesource.com/c/chromium/src/+/2450792 Original change's description: > Add a per-thread proc table using thread local storage > > In situations where both dawn_wire and dawn_native are used on separate > threads (Chrome with --single-process or --in-process-gpu), it's > desirable to have a per-thread proc table so that the WebGPU C++ API can > still be used. This eliminates classes of bugs with manual > reference/release errors. > > This also changes many of the GetProcs functions to return const > references to the static proc tables known at compile time, instead of a > copy. > > Bug: none > Change-Id: I8775bb715b312dd9476a1903fbd797d4b1302614 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/29240 > Reviewed-by: Stephen White <senorblanco@chromium.org> > Reviewed-by: Corentin Wallez <cwallez@chromium.org> > Commit-Queue: Austin Eng <enga@chromium.org> TBR=cwallez@chromium.org,senorblanco@chromium.org,enga@chromium.org Change-Id: I4587b457b7b2dd5d3c7457065bf4e77b95af59d7 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: none Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/29442 Reviewed-by: Kai Ninomiya <kainino@chromium.org> Commit-Queue: Kai Ninomiya <kainino@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 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
