Abstract

+The following document will detail GPU Support for SR-IOV, SIOV, and VFIO-Mdev functionality.

An absence of critical technical documentation has historically slowed growth and adoption of developer ecosystems for GPU virtualization. +

This CC-BY-4.0 licensed content can either be used with attribution, or used as inspiration for new documentation, created by GPU vendors for public commercial distribution as developer documentation. +

+Where possible, this documentation will clearly label dates and versions of observed-but-not-guaranteed behaviour vs. vendor-documented stable interfaces/behaviour with guarantees of forward or backward compatibility.

+

Drivers

+

The most widely used method of enabling Mdev functionality on Nvidia GPUs is via the use of Nvidia's proprietary driver package. +

Nvidia's proprietary Mdev driver supports both SR-IOV as well as software based mediation. The appropriate mode is chosen between the two methods based on hardware architecture. +

+

AMD

+

This section will cover Mdev support on AMD GPUs. +

+

Hardware

+

Supported GPUs: +

+
  • AMD FirePro S7150
    • +
  • AMD Radeon Pro V520 [15]
    • +
  • AMD FirePro W7100 [15]
+

Drivers

+

The open source GIM driver supports AMD Tonga architecture GPUs such as the FirePro S7150 & W7100. +

To make use of the MxGPU GIM driver on modern kernel versions you will require pull request 24. +

Virtualization driver support beyond AMD's Tonga architecture is unclear. +
