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
- Level Zero Tracing Layer
This project is part of the larger oneAPI project.
See the oneAPI specification for more information about the oneAPI project.
See the Level Zero specification for more information about Level Zero.
See the Level Zero specification repo for contributing to the specification.
Level Zero API versions are listed in the ze_api_version_t enumeration, located in the
ze_api.h file.
Project is defined using CMake.
mkdir build
cd build
cmake .. -D CMAKE_BUILD_TYPE=Release
cmake --build . --target package
cmake --build . --target install
The Level Zero Loader has the ability to print warnings and errors which occur within the internals of the Level Zero Loader itself.
To enable this debug tracing feature, set the environment variable ZE_ENABLE_LOADER_DEBUG_TRACE=1.
This will enforce the Loader to print all errors whether fatal or non-fatal to stderr with the PREFIX ZE_LOADER_DEBUG_TRACE:.
The Level Zero Loader uses spdlog logging and can be controlled via environment variables:
ZEL_ENABLE_LOADER_LOGGING=1
[DEPRECATED] ZEL_LOADER_LOG_FILE=/path/to/logfile
ZEL_LOADER_LOG_DIR='/directory/path'
ZEL_LOADER_LOGGING_LEVEL=debug
Valid logging levels are trace, debug, info, warn, error, critical, off. Logging is disabled by default but when enabled the default level is 'warn'. The default log file is 'ze_loader.log' in '.oneapi_logs' in the current user's home directory.
This feature is in early development and is preview only.
