Quality expectations
| Platform | OpenCL | Level Zero |
|---|---|---|
| Broadwell | 2.1 - Production | - |
| Skylake | 2.1 - Production | 0.8 - Pre-Release |
| Kaby Lake | 2.1 - Production | 0.8 - Pre-Release |
| Coffee Lake | 2.1 - Production | 0.8 - Pre-Release |

Unless noted otherwise, the driver was validated on Ubuntu 18.04 LTS with stock kernel.
For ICL and TGL platforms kernel from drm-tip repository were 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
- Level Zero loader is required to use the intel-level-zero-gpu library. v0.91.10 is the recommended version
Important changes
- Updated IGC built with llvm/clang 10
- Enabled Performance Counters for OCL and L0
- Disabled cl_khr_subgroups extension on gen12
