Version
2025.1 English

This version of Xilinx® Runtime includes the following new features and changed behavior.

AI Engine Support
Added support for multiple individual AI Engine graph run time controls. The host application can now manage multiple xrt::hw_context instances, enabling loading and reloading of the XCLBIN for AI Engine graphs.
Infrastructure
xrt::hw_context has been moved from experimental folder to the main API area. Existing paths in the experimental area remain functional for backward compatibility.
XRT header include paths have been reorganized.
  • include/*.* → include/xrt/detail
  • include/deprecated → include/xrt/deprecated
  • include/experimental → include/xrt/experimental
XRT now depends on opencl-icd-loader instead of ocl-icd. No action is required from users.
Deprecation Plan
xbutil has been renamed to xrt-smi.
You can still use xbutil in version 2025.1 of XRT. Starting from 2025.2,xbutil will be removed. Users must transition to use xrt-smi or create appropriate symbolic links.
Note: For detailed information about XRT API changes and experimental features, refer to the changelog.
