Migrate away from using recently deprecated APIs Due to a renaming/refactoring of the spvc API Dawn is currently using a deprecated class name. Fixing this, so the deprecated APIs can be removed. Also including the roll to pick up the API changes.

Dawn (formerly NXT) is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. It exposes a C/C++ API that maps almost one-to-one to the WebGPU IDL and can be managed as part of a larger system such as a Web browser.
Dawn provides several WebGPU building blocks:
dawn.json: description of the API used to drive code generators.
examples: examples showing how Dawn is used.
generator: code generator for files produces from
templates: Jinja2 templates for the generator
scripts: scripts to support things like continuous testing, build files, etc.
common: helper code shared between core Dawn libraries and tests/samples
dawn_native: native implementation of WebGPU, one subfolder per backend
dawn_wire: client-server implementation of WebGPU
include: public headers for Dawn
tests: internal Dawn tests
end2end: WebGPU tests performing GPU operations
unittests: unittests and by extension tests not using the GPU
validation: WebGPU validation tests not using the GPU (frontend tests)
utils: helper code to use Dawn used by tests and samples
third_party: directory where dependencies live as well as their buildfiles.
Dawn uses the Chromium build system and dependency management so you need to install depot_tools and add it to the PATH.
On Linux you need to have the
# Install pkg-config on Ubuntu sudo apt-get install pkg-config
Then get the source as follows:
# Clone the repo as "dawn" git clone https://dawn.googlesource.com/dawn dawn && cd dawn # Bootstrap the gclient configuration cp scripts/standalone.gclient .gclient # Fetch external dependencies and toolchains with gclient gclient sync
Then generate build files using
gn args out/Debug or
gn args out/Release. A text editor will appear asking build options, the most common option is
gn args out/Release --list shows all the possible options.
ninja -C out/Release to build dawn and for example
./out/Release/dawn_end2end_tests to run the tests.
Please read and follow CONTRIBUTING.md. Dawn doesn‘t have a formal coding style yet, except what’s defined by our clang format style. Overall try to use the same style and convention as code around your change.
