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/19.48.14977/intel-gmmlib_19.3.4_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.48.14977/intel-igc-core_1.0.2990_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.48.14977/intel-igc-opencl_1.0.2990_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.48.14977/intel-opencl_19.48.14977_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/19.48.14977/intel-ocloc_19.48.14977_amd64.deb

3. Verify sha256 sums for packages

Example:

wget https://github.com/intel/compute-runtime/releases/download/19.48.14977/ww48.sum
sha256sum -c ww48.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 platform kernel from drm-tip repository was used at
commit 7536bf946d840e2afaa028c281b7ecfcf333951e 2019-10-14_17-52-25 drm-tip: 2019y-10m-14d-17h-51m-24s UTC integration manifest

Quality levels

• Experimental - no quality expectations
• Early support - platform may not be available on the market yet
• Beta - suitable for integration and broad testing
• Production - Beta + meets Khronos certification requirements; suitable for production

Issues & regressions of note

• Fine grained SVM is not supported in this release. Please see issue #34 for details.
• For ICL platform i915.alpha_support=1 kernel parameter is required for kernel before 5.2
• ICL certification issue rootcaused as test issue (timeout) – execution time increased after 64-bit atomics were enabled.

Important changes

• Updated Intel Graphics Compiler
