Quality expectations

Platform OpenCL Level Zero
Broadwell 3.0 - Production -
Skylake 3.0 - Production 1.0 - Pre-Release
Kaby Lake 3.0 - Production 1.0 - Pre-Release
Coffee Lake 3.0 - Production 1.0 - Pre-Release
Ice Lake 3.0 - Production 1.0 - Pre-Release
Tiger Lake 3.0 - Production 1.0 - Pre-Release
Apollo Lake 3.0 - Beta -
Gemini Lake 3.0 - Beta -
Elkhart Lake 3.0 - Early support -

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
  • Ice Lake was tested on Ubuntu 20.04 LTS with stock kernel
  • Gemini Lake was tested on Ubuntu 18.04.1 LTS with stock kernel

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
  • Gen9 Atom platforms (Apollo Lake / Gemini Lake) downgraded due to compiler regression in math_brute_force pown conformance test

Important changes

  • Updated IGC
  • Updated Level Zero Loader
  • Switched to C++17
