This patch series extends the crypto adapter pass-through support to
provide safeguards against inadvertent sharing of AP resources between
guests and/or the host, and to implement more of the s390 AP
architecture related to provisioning and dynamic configuration of
AP resources.
Change log v1->v2:
-----------------
* Removed patches preventing root user from unbinding AP queues from
the vfio_ap device driver
* Introduced a shadow CRYCB in the vfio_ap driver to manage dynamic
changes to the AP guest configuration due to root user interventions
or hardware anomalies.
Tony Krowiak (8):
s390: vfio-ap: maintain a shadow of the CRYCB in use by a guest
s390: vfio-ap: sysfs interface to display guest CRYCB
s390: vfio-ap: allow assignment of unavailable AP resources to mdev
device
s390: vfio-ap: allow hot plug/unplug of AP resources using mdev device
s390: vfio-ap: wait for queue empty on queue reset
s390: kvm: test CRYCB masks before setting them
s390: vfio-ap: handle bind and unbind of AP queue device
s390: vfio-ap: update documentation
