<h2><span class="mw-headline" id="Abstract">Abstract</span></h2><p>
The following document will detail GPU Support for SR-IOV, SIOV, and VFIO-Mdev functionality.</p><blockquote><p>An absence of critical technical documentation has historically slowed growth and adoption of developer ecosystems for GPU virtualization.
</p><p>This <a rel="nofollow" class="external text" href="https://creativecommons.org/licenses/by/4.0/">CC-BY-4.0</a> licensed content can either be used with attribution, or used as inspiration for new documentation, created by GPU vendors for public commercial distribution as developer documentation.
</p><p>
Where possible, this documentation will clearly label dates and versions of observed-but-not-guaranteed behaviour vs. vendor-documented stable interfaces/behaviour with guarantees of forward or backward compatibility.</p></blockquote>

<p>The most widely used method of enabling Mdev functionality on Nvidia GPUs is via the use of Nvidia's proprietary driver package.
</p><p>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.

<p>The open source <a rel="nofollow" class="external text" href="https://github.com/GPUOpen-LibrariesAndSDKs/MxGPU-Virtualization">GIM driver</a> supports AMD Tonga architecture GPUs such as the FirePro S7150 & W7100.
