[RFC PATCH 0/2] vfio-ccw: Implement request notifier

Posted by Eric Farman 3 years, 5 months ago

This is the corresponding QEMU code for the kernel series posted here:

https://lore.kernel.org/kvm/20201117032139.50988-1-farman@linux.ibm.com/

Long story short, when a device disappears because of a subchannel
event, userspace can receive a notification that the device should
be released as it is no longer usable. This implements that for the
vfio-ccw interface.
