2D array texture may corrupt on some Intel devices, making out-of-bound texture access and memory information leak. It's a critical security issue. Intel driver team suggested the 24K extra memory approach in order to mitigate the security issue before. However, the texture corruption issue (and even the correctness issue) can be worked around via allocating a few extra layers. And patches have already been merged in Dawn, with a lot tests for verification. The 24K extra memory for each texture is actually incorrect and unnecessary. So this patch removes relevant code in Dawn. This patch mainly reverts some code of this patch below: https://dawn-review.googlesource.com/c/dawn/+/96220 Bug: dawn:1507 Change-Id: Ic3239115ad4c74bdee928577ccbb20f1e35d13c3 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/114641 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Austin Eng <enga@chromium.org> Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Yunchao He <yunchao.he@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, 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.
