Installation procedure on Ubuntu 18.04

1. Create temporary directory

Example:

mkdir neo

2. Download all *.deb packages

Example:

cd neo
wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/intel-gmmlib_20.1.1_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/intel-igc-core_1.0.3951_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/intel-igc-opencl_1.0.3951_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/intel-opencl_20.19.16754_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/intel-ocloc_20.19.16754_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/intel-level-zero-gpu_0.8.16754_amd64.deb

3. Verify sha256 sums for packages

Example:

wget https://github.com/intel/compute-runtime/releases/download/20.19.16754/ww19.sum
sha256sum -c ww19.sum

4. Install all packages as root

Example:

sudo dpkg -i *.deb

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

Important changes

• Updated IGC
• Updated coherency support on Gen11/Gen12 to reflect HW capabilities
• Added new interface for media sharing to exchange format info
