Unless noted otherwise, the driver was validated on Ubuntu 18.04 LTS with stock kernel.
For ICL platform kernel from drm-tip repository was used at
commit c8c778558fd52abd3303d8ea324df788062adc97 2019-05-14_07-38-40 drm-tip: 2019y-05m-14d-07h-37m-46s UTC integration manifest
Quality levels
- Experimental - no quality expectations
- Early support - platform may not be available on the market yet
- Beta - suitable for integration and broad testing
- Production - Beta + meets Khronos certification requirements; suitable for production
Issues & regressions of note
- Fine grained SVM is not supported in this release. Please see issue #34 for details.
- For ICL platform i915.alpha_support=1 kernel parameter is required for kernel before 5.2
- Regression in optional extensions cl_khr_int64_base_atomics and cl_khr_int64_extended_atomics
Important changes
- Updated Intel Graphic Compiler to 1.0.11-2500 (intel/intel-graphics-compiler@6dd3bde
