VFIO Device Assignment Quirks and How to Avoid Them

In this presentation, Alex Williamson will provide case studies through various examples of troublesome configurations and the workarounds, or quirks, that are sometimes employed to enable them. These quirks are however not without pitfalls and can impose performance, maintenance, functionality, and time-to-market downsides. The goal of this talk is to share some of these common issues, expose the quirks available as workarounds, and discuss how they can be avoided entirely with well-informed hardware design.
