oneAPI Level Zero

This repository contains the following components of oneAPI:

  • Copies of the Level Zero Specification API C/C++ header files
  • Level Zero Loader
  • Level Zero Validation Layer

This project is part of the larger oneAPI project. See Contributing below for details about submitting issues and pull requests.

oneAPI Specification: https://spec.oneapi.com/versions/latest/introduction.html

The versions of the Level Zero API are listed in the file ze_driver.h in the ze_api_version_t enum.

Building and Installing

Project is defined using CMake.

The OpenCL headers are required for interop support. If they are installed in a non-standard location, specify their prefix with -D OPENCL_PATH=<prefix>.

mkdir build
cd build
cmake ..
cmake --build . --config Release
cmake --build . --config Release --target package
cmake --build . --config Release --target install

Ubuntu with Docker

mkdir build
mkdir -p .ccache

docker run \
  --rm \
  -v $PWD:$PWD \
  -w $PWD/build \
  -e CCACHE_DIR=$PWD/.ccache \
  -e CCACHE_BASEDIR=$PWD \
  $(docker build -q \
      --build-arg UID=$(id -u) \
      --build-arg GID=$(id -g) \
      --build-arg IMAGE_VERSION=eoan \
