| D | vfio-ccw.rst | 2 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
40 For vfio mediated device framework:
