Quality expectations

Platform	OCL	Quality
Broadwell	2.1	Pre-Release
Skylake	2.1	Pre-Release
Kaby Lake	2.1	Pre-Release
Coffee Lake	2.1	Pre-Release
Cannon Lake	2.1	Experimental
Apollo Lake	1.2	Pre-Release
Gemini Lake	1.2	Pre-Release

Unless noted otherwise, the driver was validated on Ubuntu 18.04 LTS with stock kernel.

Quality levels:

• Experimental - no quality expectations
• Pre-Release - major issues or regressions; suitable for preliminary checkout
• Beta - no known major issues or regressions; suitable for integration and broad testing
• Production - Beta + meets Khronos certification requirements; suitable for production

Issues & regressions of note

• All platforms downgraded to Pre-Release quality due to regression in cl_intel_motion_estimation and cl_intel_advanced_motion_estimation extensions. Fix in progress
• Fine grained SVM is not supported in this release. Please see issue #34 for details.
• For CFL platform i915.alpha_support=1 kernel parameter is required under Ubuntu 16.04.4 with default kernel 4.13
