This reverts commit 63f2666ee77c987a56c6be5bfc6bbb10d12a9f63. Reason for revert: causes failures in dawn_unittests after Dawn uses SPVC by default. We need a fix in both SPVC and this CL before re-landing. Original change's description: > Check bind group layout with storage texture in pipeline descriptors > > This patch adds all the validations on the use of bind group layout with > read-only storage texture and write-only storage texture in the creation > of pipeline objects. > > 1. GPUBindGroupLayout.bindingType must match the type of the storage > texture variable (read-only or write-only) in shader. > 2. GPUBindGroupLayout.storageTextureFormat must be a valid texture > format that supports STORAGE usage. > 3. GPUBindGroupLayout.storageTextureFormat must match the storage > texture format declaration in shader. > 4. GPUBindGroupLayout.textureDimension must match the storage texture > dimension declared in shader. > > BUG=dawn:267 > TEST=dawn_unittests > > Change-Id: Ifa3c2194dc76de14f790a0a73868e69bbb31c814 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/17167 > Commit-Queue: Jiawei Shao <jiawei.shao@intel.com> > Reviewed-by: Kai Ninomiya <kainino@chromium.org> TBR=cwallez@chromium.org,kainino@chromium.org,yunchao.he@intel.com,jiawei.shao@intel.com,shaobo.yan@intel.com,hao.x.li@intel.com,enga@chromium.org,jiajie.hu@intel.com Change-Id: Idb4083b11f22fa7e4c5c8477bc4b65b58900746e No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: dawn:267 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/17380 Reviewed-by: Jiawei Shao <jiawei.shao@intel.com> Commit-Queue: Jiawei Shao <jiawei.shao@intel.com>
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
