  • Tesla M10
  • Tesla M6
  • GRID K2 (Citrix XenServer and VMware ESXi only)
  • GRID K1 (Citrix XenServer and VMware ESXi only)

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. Modern kernel versions require pull request 24
