Runtime Implementations Supported
- intel-level-zero-gpu (https://github.com/intel/compute-runtime/releases)
- Minimum required version 21.09.19150
New to this Release:
- New Tracing Layer APIs to support tracing Level Zero core APIs introduced after the 1.0 Specification. A change of design was needed to allow extension to new APIs without breaking backwards compatibility of original tracing APIs. The original tracing layer APIs will continue to be supported for 1.0 core APIs, but users are encouraged to switch to the new tracing layer APIs.
- New Loader API to retrieve version information of loader and layers:
zelLoaderGetVersions - Enabled discovery of Level Zero Compute Accelerators Drivers on windows
- Added CHANGELOG.md
- Bug Fixes:
- Fixed loader bug that could cause corruption of handles when there are multiple drivers loaded.
- Corrected version check in layers to future-proof compatibility checks

- Improved library variable lifetime management by initializing variables at load time rather than as static globals.
- Added environment variable that allows optionally specifying runtime drivers to use on Linux
- Note: Tracing Layer support is not yet available for the APIs newly introduced in the 1.1 spec. Tracing layer support for all other APIs remains functional.

New to this Release:
Note: Level Zero Specification API did not change.
- Update loader library to 1.1.0 to indicate addition of tracing layer implementation and associated APIs
- Fixed bug when reading windows environment variables set by process before zeInit call. Before variables were not read correctly resulting in layers not being enabled as expected
- Fixed bug in loader when using multiple drivers and a driver API returns an error code. Previously loader would incorrectly translate output handles from failed API calls
- Deprecated a tracing implementation layer descriptor enum value due to incorrect name and added a replacement.

Fixed Issues:
- When multiple windows drivers were installed and one was disabled, zeInit would fail the entire init process. This has been fixed and the enabled driver can still be used
- When using multiple drivers some input handles were modified by loader. This has been fixed.

phCommandLists. Workaround: Save command list handles in a temp variable before calling, and restore value after.
