Intel GPU Level-Zero sidecar
Table of Contents
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
