Unless noted otherwise, the driver was validated on Ubuntu 18.04 LTS with stock kernel.
Moving to Ubuntu 20.04 for testing soon.
(*) Product is based on a published Khronos specification and is expected to pass the Khronos Conformance Process when available. Current conformance status can be found at https://www.khronos.org/conformance.
(*) For ICL and TGL platforms kernel from drm-tip repository was used:
- 5.6.0-rc7 commit 257af0ddcea3a234dcb79579600f971edd47353f 2020-03-23_15-07-40 drm-tip: 2020y-03m-23d-15h-06m-46s UTC integration manifest
Quality levels
- Experimental - no quality expectations
- Early support - platform may not be available on the market yet
- Pre-Release - suitable for integration and testing, gathering customer feedback
- Beta - suitable for integration and broad testing
- Production - Beta + meets API-specific conformance requirements; suitable for production
Issues & regressions of note
- For ICL platform i915.alpha_support=1 kernel parameter is required for kernel before 5.2
- OpenCL and Level Zero packages provided in this release were compiled with DG1 support disabled
