This reverts commit 4e17d5c2483b63d4863162d692a1a961d1dcb958. Reason for revert: broken on chromeos Original change's description: > Remove VK_DEFINE_NON_DISPATCHABLE_HANDLE magic, use explicit VkHandle wrapper > > Overriding VK_DEFINE_NON_DISPATCHABLE_HANDLE changes the function > signatures of Vulkan functions, changing their ABI and making us > incompatible with real drivers. This removes that magic, and replaces it > with an explicit wrapper, VkHandle, which has much of the same > functionality as the original VkNonDispatchableHandle. > > It adds definitions for dawn_native::vulkan::VkBuffer et al, which > shadow the native ::VkBuffer et al. This retains type safety throughout > the Vulkan backend without changing every single usage. > > Notably, the following things had to change: > - An explicit conversion from VkBuffer* to ::VkBuffer* is needed for > arrays. This is implemented as a reinterpret_cast, which is still > safe as the new VkHandle still has the same memory layout properties > as VkNonDispatchableHandle did. > - When pointing to a VkHandle as an output pointer, it's now necessary > to explicitly get the native ::VkBuffer (via operator*) and point to it. > > Bug: chromium:1046362 > Change-Id: I9c5691b6e295aca1b46d4e3d0203956e4d570285 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/15580 > Reviewed-by: Austin Eng <enga@chromium.org> > Reviewed-by: Kai Ninomiya <kainino@chromium.org> > Commit-Queue: Kai Ninomiya <kainino@chromium.org> TBR=cwallez@chromium.org,kainino@chromium.org,enga@chromium.org Change-Id: I500df2e34fd0f245ad04c517ff028ddd7bb5a2bf No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: chromium:1046362 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/15620 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
