Drivers
In order to use Mdev with Nvidia GPUs, a proprietary enterprise driver is required.
The Nvidia driver supports both SR-IOV and software based mediation and chooses between them based on what the installed GPU supports.
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:
Drivers
The open source GIM driver supports AMD Tonga architecture GPUs such as the FirePro S7150/W7100. Modern kernel versions require pull request 24.
