Nvidia

This section will cover Mdev support on Nvidia GPUs.

Hardware

  • 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 [4]
  • NVIDIA A100 HGX 80GB
  • NVIDIA A100 PCIe 80GB (SR-IOV: 20VF [5])
  • NVIDIA A100X
  • NVIDIA A100 HGX 40GB
  • NVIDIA A100 PCIe 40GB (SR-IOV: 16VF [6])
  • NVIDIA A40 (SR-IOV: 32VF [7])
  • NVIDIA A30 (SR-IOV: 8VF [8])
  • NVIDIA A30X
  • NVIDIA A16 (SR-IOV: 16VF [9])
  • NVIDIA A10 (SR-IOV: 32VF [10])
  • NVIDIA A2 (SR-IOV: 16VF [11])
  • NVIDIA RTX A6000
  • NVIDIA RTX A5000
  • Quadro RTX 8000 (SR-IOV: 24 VF [12])
  • Quadro RTX 8000 passive
  • Quadro RTX 6000 (SR-IOV: 24 VF [13])
  • Quadro RTX 6000 passive

  • Tesla T4 (SR-IOV: 16VF [14])
  • Tesla P100
  • Tesla P40
  • Tesla P6
  • Tesla P4
  • Tesla M60
  • 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.

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.
