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-1.0.11485/intel-igc-core_1.0.11485_amd64.deb
wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.11485/intel-igc-opencl_1.0.11485_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/22.28.23726/intel-level-zero-gpu-dbgsym_1.3.23726_amd64.ddeb
wget https://github.com/intel/compute-runtime/releases/download/22.28.23726/intel-level-zero-gpu_1.3.23726_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/22.28.23726/intel-opencl-icd-dbgsym_22.28.23726_amd64.ddeb

wget https://github.com/intel/compute-runtime/releases/download/22.28.23726/libigdgmm12_22.1.3_amd64.deb

1. Verify sha256 sums for packages

Example:

wget https://github.com/intel/compute-runtime/releases/download/22.28.23726/ww28.sum
sha256sum -c ww28.sum

1. Install all packages as root

Example:

sudo dpkg -i *.deb

Quality expectations

All other platforms were validated on Ubuntu 20.04 LTS with stock kernel, unless noted otherwise.
DG1 was tested with drm-tip kernel v.5.16 rc3.

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

• Change 5cd2e09, related to ze_device_properties_t is included in this build. While functionally correct, it may break Level Zero applications that incorrectly initialize this data structure. OpenCL is unaffected.

Additional information

• packages were built with custom flag NEO_ENABLE_i915_PRELIM_DETECTION=1

Important changes

• update gen9 and gen11 support flags
• Add support for ze_device_memory_ext_properties_t
