Intel GPU Level-Zero sidecar

Introduction

Intel GPU Level-Zero sidecar is an extension for the Intel GPU plugin to query additional GPU details from the oneAPI/Level-Zero API. As the Level-Zero is a C/C++ API, it is preferred to keep the original GPU plugin as-is and add the additional functionality via the Level-Zero sidecar. The GPU plugin can be configured to use the Level-Zero sidecar with an overlay, see install.

Intel GPU plugin and the Level-Zero sidecar communicate via gRPC on a local socket visible only to the containers.

Note

: Intel Device Plugin Operator doesn't yet support enabling Level-Zero sidecar in the GPU CR object.

Modes and Configuration Options

Flag	Argument	Default	Meaning
-socket	unix socket path	/var/lib/levelzero/server.sock	Unix socket path which the server registers itself into.
-wsl	-	disabled	Adapt sidecar to run in the WSL environment.
-v	verbosity	1	Log verbosity

Install

Installing the sidecar along with the GPU plugin happens via two possible overlays: health and wsl.

Health overlay adds the sidecar to the base GPU plugin deployment and configures GPU plugin to retrieve device health indicators from the Level-Zero API:

$ kubectl -k deployments/gpu_plugin/overlays/health

WSL layer enables Intel GPU detection with WSL (Windows Subsystem for Linux) Kubernetes clusters. It also leverages the Level-Zero sidecar:

$ kubectl -k deployments/gpu_plugin/overlays/wsl
