Subject: [PATCH v3 0/1] s390: vfio_ap: link the vfio_ap devices to the vfio_ap bus subsystem
Date: Thu, 21 Feb 2019 15:14:53 +0100 [thread overview]
Message-ID: <1550758494-28227-1-git-send-email-pmorel@linux.ibm.com> (raw)
The goal of this patch is to standardize the device-driver interface
for the VFIO_AP ap_matrix_device to satisfy user-land tools working on
hot-plug (UDEV/LIBVIRT).
Christian Borntraeger reported libvirt looping when a matrix device
was available before the libvirt start.
Marc Hartmayer debugged this and circumvented this in libvirt:
