Intel(R) Graphics Compute Runtime for OpenCL(TM)

Introduction

The Intel(R) Graphics Compute Runtime for OpenCL(TM) is a open source project to converge Intel's development efforts on OpenCL(TM) compute stacks supporting the GEN graphics hardware architecture.

Please refer to http://01.org/compute-runtime for additional details regarding Intel's motivation and intentions wrt OpenCL support in the open source.

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 has the following functional delta compared to previously released drivers:

Generic extensions

  • cl_khr_mipmap
  • cl_khr_mipmap_writes
  • cl_khr_priority_hints
  • cl_khr_throttle_hints
  • 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)
