  • Tesla M60
  • Tesla M10
  • Tesla M6
  • GRID K2 (Citrix XenServer and VMware ESXi only)
  • GRID K1 (Citrix XenServer and VMware ESXi only)

Additionally supported GPUs with VGPU Unlock:

  • All(?) Volta based GPUs (V-series)
  • All(?) Turing based GPUs (20-series)
  • All(?) Pascal based GPUs (10-series)
  • Most Maxwell based GPUs (9-series) with the following notable exceptions:
    • GTX 970 (mixed FB regions)
    • Quadro M2000 (mixed FB regions)
    • Tesla M40 [15]

Drivers

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

Licensing

Usage of the proprietary enterprise driver is subject to license fees.

AMD

This section will cover Mdev support on AMD GPUs.

Hardware

Supported GPUs:

  • AMD FirePro S7150
  • AMD Radeon Pro V520 [16]
  • 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
