Platform Device Passthrough Using VFIO - Stuart Yoder, Freescale Semiconductor

Sign up or log in to save this to your schedule and see who's attending!

VFIO provides a framework for securely allowing user space applications to
directly access and use I/O devices, including QEMU which allows pass-
through of devices to virtual machines. QEMU and the upstream Linux kernel
currently support VFIO for PCI devices.  System-on-a-chip processors frequently
have I/O devices that are not PCI-based and use the platform bus framework
in Linux.  An increasing number of QEMU/KVM users have the need to pass
through platform devices to virtual machines using VFIO.

This presentation describes:
  1. vfio
  2. how VFIO-based passthrough of PCI devices is similar and different for platform devices
  3. issues and challenges in solving platform device pass-through
  4. proposed kernel changes to enable this
