[Qemu-devel] [PATCH v2 0/5] s390x: vfio-ap: guest dedicated crypto adapters

[Tony Krowiak <akrowiak@linux.vnet.ibm.com>]

This patch series is the QEMU counterpart to the KVM/kernel support for 
guest dedicated crypto adapters. The KVM/kernel model is built on the 
VFIO mediated device framework and provides the infrastructure for 
granting exclusive guest access to crypto devices installed on the linux 
host. This patch series introduces a new QEMU command line option, QEMU 
object model and CPU model features to exploit the KVM/kernel model.

See the detailed specifications for AP virtualization provided by this 
patch set in docs/vfio-ap.txt for a more complete discussion of the 
design introduced by this patch series.

v1 -> v2 Change log:
===================
* Removed unnecessary S390APMatrixDevice, S390APMatrixDeviceClass 
* Removed ioctl to configure the AP matrix for the guest: letting the
  vfio_ap device driver's 'open' callback configure the AP matrix
  for the guest
* Removed masks from object model: Unnecessary at this point because they 
  are not currently used 
* Renamed:
  * VFIOAPMatrixDevice to VFIOAPDevice
  * VFIOAPMatrixDeviceClass to VFIOAPDeviceClass
  * APMatrixDevice to APDevice
  * APMatrixDeviceClass to APDeviceClass
  * ap-matrix.c to ap.c (in hw/vfio)
  * ap-matrix-device.c to ap-device.c (in hw/s390x)
  * ap-matrix-device.h to ap-device.h (in include/hw/s390x)
* Added CPU model feature for AP facilities installed on guest and 
  facilities features for QCI Instructions Available (STFLE.12) and AP 
  Facilities Test facility installed (STFLE.15).
