GPU Support
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:
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.
