This patch fixes a bug in buffer-to-texture and texture-to-buffer copies when copySize.height == 0 or copySize.depth == 0. Previously we miss the checks if either copySize.height or copySize.depth is 0 before doing (copySize.height / blockHeight - 1) and (copySize.depth - 1) thus we will get incorrect results because of arithmetic overflows. This patch fixes this bug by adding the missed check and adds the related regression tests in dawn_unittests BUG=dawn:453 TEST=dawn_unittests Change-Id: I970e420c0fa7f0b61c656365bef079c123a59e6a Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/23520 Commit-Queue: Kai Ninomiya <kainino@chromium.org> Reviewed-by: Austin Eng <enga@chromium.org> Reviewed-by: 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
