26 example assumes the pds_core and pds-vfio-pci modules are already

8 The vfio-pci driver exists as a device agnostic driver using the
11 vfio-pci driver does include some device specific support, further
13 sustainable. The vfio-pci driver has therefore split out
14 vfio-pci-core as a library that may be reused to implement features
21 accessible via the vfio-pci base driver. Authors of such drivers
32 available to the user via vfio-pci, what safeguards exist to validate
35 to the overall vfio maintainer.
A Dvfio.rst81 is created by simply opening the /dev/vfio/vfio character device.
