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.

Drivers
The open source GIM driver supports AMD Tonga architecture GPUs such as the FirePro S7150/W7100. Modern kernel versions require pull request 24
