[Qemu-devel] [PATCH v10 1/6] linux-headers: linux header updates for AP support
Posted by Tony Krowiak 7 years, 4 months ago
Updates the linux header files in preparation for introduction
of the VFIO AP device:

* Added device attributes to the KVM_S390_VM_CRYPTO group
  to indicate whether AP instructions are to be interpreted

* Added VFIO device information for AP devices

The needed changes are all in kvm/next, and we're near the next Linux
merge window, so I'll just replace this one with a proper header sync
against kvm/next.
