Fabian Zwolinski aa3dfbf90e Add missing output capture in ULT
Unit tests should not write output to the console.
Instead, every output should be captured.

Intel(R) Graphics Compute Runtime for oneAPI Level Zero and OpenCL(TM) Driver

Introduction

The Intel(R) Graphics Compute Runtime for oneAPI Level Zero and OpenCL(TM) Driver is an open source project providing compute API support (Level Zero, OpenCL) for Intel graphics hardware architectures (HD Graphics, Xe).

What is NEO?

NEO is the shorthand name for Compute Runtime contained within this repository. It is also a development mindset that we adopted when we first started the implementation effort for OpenCL.

The project evolved beyond a single API and NEO no longer implies a specific API. When talking about a specific API, we will mention it by name (e.g. Level Zero, OpenCL).

Supported Platforms

Platform OpenCL Level Zero
Intel Core Processors with Gen8 graphics devices (formerly Broadwell) 3.0 -
Intel Core Processors with Gen9 graphics devices (formerly Skylake, Kaby Lake, Coffee Lake) 3.0 Y
Intel Atom Processors with Gen9 graphics devices (formerly Apollo Lake, Gemini Lake) 3.0 -
Intel Core Processors with Gen11 graphics devices (formerly Ice Lake) 3.0 Y
Intel Atom Processors with Gen11 graphics devices (formerly Elkhart Lake) 3.0 -
Intel Core Processors with Gen12 graphics devices (formerly Tiger Lake, Rocket Lake, Alder Lake) 3.0 Y

Release cadence

Release cadence changed from weekly to monthly late 2022

  • At the beginning of each calendar month, we identify a well-tested driver version from the previous month as a release candidate for our monthly release.
  • We create a release branch and apply selected fixes for significant issues.
  • The branch naming convention is releases/yy.ww (yy - year, ww - work week of release candidate)
  • The builds are tagged using the following format: yy.ww.bbbbb.hh (yy - year, ww - work week, bbbbb - incremental build number from the master branch, hh - incremental commit number on release branch).
  • We publish and document a monthly release from the tip of that branch.
  • During subsequent weeks of a given month, we continue to cherry-pick fixes to that branch and may publish a hotfix release.
  • Quality level of the driver (per platform) will be provided in the Release Notes.

Installation Options

To allow NEO access to GPU device make sure user has permissions to files /dev/dri/renderD*.

Via system package manager

NEO is available for installation on a variety of Linux distributions and can be installed via the distro's package manager.

For example on Ubuntu* 22.04:

apt-get install intel-opencl-icd

Manual download

.deb packages for Ubuntu are provided along with installation instructions and Release Notes on the release page

Linking applications

Directly linking to the runtime library is not supported:

Dependencies

In addition, to enable performance counters support, the following packages are needed:

How to provide feedback

By default, please submit an issue using native github.com interface.

How to contribute

Create a pull request on github.com with your patch. Make sure your change is cleanly building and passing ULTs. A maintainer will contact you if there are questions or concerns. See contribution guidelines for more details.
