[PATCH v3 04/14] KVM: s390: device attribute to set AP interpretive execution

2018-03-14 Thread Tony Krowiak
The VFIO AP device model exploits interpretive execution of AP instructions (APIE) to provide guests passthrough access to AP devices. This patch introduces a new device attribute in the KVM_S390_VM_CRYPTO device attribute group to set APIE from the VFIO AP device defined on the guest.
