How to provide feedback
By default, please submit an issue using native github.com interface: https://github.com/intel/compute-runtime/issues.
How to contribute
Create a pull request on github.com with your patch. Make sure your change is cleanly building and passing ULTs. A maintainer will contact you if there are questions or concerns.
Known Issues and Limitations
OpenCL compliance of a driver built from open-source components should not be assumed by default. Intel will clearly designate / tag specific builds to indicate production quality including formal compliance. Other builds should be considered experimental.
The driver requires Khronos ICD loader to operate correctly: https://github.com/KhronosGroup/OpenCL-ICD-Loader
The driver has the following functional delta compared to previously released drivers:
- Intel's closed source SRB5.0 driver (aka Classic)
https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver - Intel's former open-source Beignet driver
https://01.org/beignet
Generic extensions
- cl_khr_mipmap
- cl_khr_mipmap_writes
- cl_khr_fp64
Preview extensions
- cl_intelx_video_enhancement
- cl_intelx_video_enhancement_camera_pipeline
- cl_intelx_video_enhancement_color_pipeline
- cl_intelx_hevc_pak
Other capabilities
- OpenGL sharing with MESA driver
- CL_MEM_SVM_FINE_GRAIN_BUFFER (if using unpatched i915)
