D3D12: Support [[num_workgroups]] for DispatchIndirect This patch supports [[num_workgroups]] on D3D12 for DispatchIndirect by appending the values of [[num_workgroups]] at the end of the scratch buffer for indirect dispatch validation and setting them as the root constants in the command signature. With this patch, for every DispatchIndirect call: - On D3D12: 1. Validation enabled, [[num_workgroups]] is used The dispatch indirect buffer needs to be validated, duplicated and be written into a scratch buffer (size: 6 * uint32_t). 2. Validation enabled, [[num_workgroups]] isn't used The dispatch indirect buffer needs to be validated and be written into a scratch buffer (size: 3 * uint32_t). 3. Validation disabled, [[num_workgroups]] is used The dispatch indirect buffer needs to be duplicated and be written into a scratch buffer (size: 6 * uint32_t). 4. Validation disabled, [[num_workgroups]] isn't used Neither transformations or scratch buffers are needed for the dispatch call. - On the other backends: 1. Validation enabled, The dispatch indirect buffer needs to be validated and be written into a scratch buffer (size: 3 * uint32_t). 2. Validation disabled, Neither transformations or scratch buffers are needed for the dispatch call.

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:
