Installation procedure on Ubuntu 22.04

1. Create temporary directory

Example:

mkdir neo

1. Download all *.deb packages

Example:

cd neo
wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.12260/intel-igc-core_1.0.12260_amd64.deb
wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.12260/intel-igc-opencl_1.0.12260_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/22.40.24364/intel-level-zero-gpu-dbgsym_1.3.24364_amd64.ddeb
wget https://github.com/intel/compute-runtime/releases/download/22.40.24364/intel-level-zero-gpu_1.3.24364_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/22.40.24364/intel-opencl-icd-dbgsym_22.40.24364_amd64.ddeb

wget https://github.com/intel/compute-runtime/releases/download/22.40.24364/libigdgmm12_22.2.0_amd64.deb

1. Verify sha256 sums for packages

Example:

wget https://github.com/intel/compute-runtime/releases/download/22.40.24364/ww40.sum
sha256sum -c ww40.sum

1. Install all packages as root

Example:

sudo dpkg -i *.deb

Quality expectations

All other platforms were validated on Ubuntu 22.04 LTS with stock kernel, unless noted otherwise. (Elkhart Lake on Ubuntu 20.04)
DG1 was tested with drm-tip kernel v.5.18.0

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.

Known issues

• Compiler regression: starting with commit 6d2e0ce, causing crash in selected ISPC workloads on Intel® Arc™ GPU. Fixed with f5a2985
• Changes introduced in af3dd28 revealed failures in higher level libraries, causing segmentation fault in oneDAL & ispc due to incorrect initialization of the ze_device_properties_t datastructures. ISPC fixed with c12c708. OneDAL – fix pending

Additional information

• packages were built with custom flag NEO_ENABLE_i915_PRELIM_DETECTION=1
