H A Dvfio-ccw.rst2 vfio-ccw: the basic infrastructure
8 Here we describe the vfio support for I/O subchannel devices for
9 Linux/s390. Motivation for vfio-ccw is to passthrough subchannels to a
10 virtual machine, while vfio is the means.
20 Thus when we introduce vfio support for these devices, we realize it
21 with a mediated device (mdev) implementation. The vfio mdev will be
23 vfio framework. And we add read/write callbacks for special vfio I/O

H A Dpds_vfio_pci.rst14 The ``pds-vfio-pci`` module is a PCI driver that supports Live Migration
20 The pds-vfio-pci device is enabled via multiple configuration steps and
26 example assumes the pds_core and pds-vfio-pci modules are already
38 # Prevent non-vfio VF driver from probing the VF device
44 # Allow the VF to be bound to the pds-vfio-pci driver
45 echo "pds-vfio-pci" > /sys/class/pci_bus/$PF_BUS/device/$VF_BDF/driver_override
47 # Bind the VF to the pds-vfio-pci driver

H A Dvfio-pci-device-specific-driver-acceptance.rst3 Acceptance criteria for vfio-pci device specific driver variants
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.
