* Allow unconsumed inputs in fragment shaders by removing them from vertex outputs when generating HLSL. Fixes https://github.com/gfx-rs/wgpu/issues/3748 * Add naga:🔙:hlsl::FragmentEntryPoint for providing information about the fragment entry point when generating vertex entry points via naga:🔙:hlsl::Writer::write. Vertex outputs not consumed by the fragment entry point are omitted in the final output struct. * Add naga snapshot test for this new feature, * Remove Features::SHADER_UNUSED_VERTEX_OUTPUT, StageError::InputNotConsumed, and associated validation logic. * Make wgpu dx12 backend pass fragment shader info when generating vertex HLSL. * Add wgpu regression test for allowing unconsumed inputs. * Address review * Add note that nesting structs for the inter-stage interface can't happen. * Remove new TODO notes (some addressed and some transferred to an issue https://github.com/gfx-rs/wgpu/issues/5577) * Changed issue that regression test refers to 3748 -> 5553 * Add debug_assert that binding.is_some() in hlsl writer * Fix typos caught in CI Also, fix compiling snapshot test when hlsl-out feature is not enabled.
deno_webgpu
This op crate implements the WebGPU API as defined in https://gpuweb.github.io/gpuweb/ in Deno. The implementation targets the spec draft as of March 31, 2024. The spec is still very much in flux. This extension tries to stay up to date with the spec, but is constrained by the features implemented in our GPU backend library wgpu.
The spec is still very bare bones, and is still missing many details. As the spec becomes more concrete, we will implement to follow the spec more closely.
In addition, setting the DENO_WEBGPU_TRACE environmental variable will output
a
wgpu trace
to the specified directory.
For testing this op crate will make use of the WebGPU conformance tests suite, running through our WPT runner. This will be used to validate implementation conformance.
GitHub CI doesn't run with GPUs, so testing relies on software like DX WARP & Vulkan lavapipe. Currently, only using DX WARP works, so tests are only run on Windows.
