Quality expectations

All platforms were validated on Ubuntu 20.04 LTS with stock kernel, with the following exceptions:

• Tiger Lake was tested with kernel from drm-tip
  5.8.0-rc7 commit ebef75fc1a3f0abebf46d7270128553f82361bc8 2020-08-02_07-12-33 drm-tip: 2020y-08m-02d-07h-11m-48s 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
• Maintenance - Reduced test frequency compared to Production, no longer recommended for new deployments. Reactive support for customers.

Issues & regressions of note

• OpenCL and Level Zero packages provided in this release were compiled with DG1 support disabled
• Unit tests compilation failed with gcc 11, fix in progress
