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. Note: This series implements the minimal viable product (MVP) and does not provide support for hot plug/unplug, migration, or VSIE. The goal of the MVP model is to solidify a base upon which these additional features will be built. v4 => v5 Change log: =================== * Added MAINTAINERS entries for VFIO AP * Added explanation for why we are only supporting zEC12 and newer CPU models. * Changed CPU model feature qci=on|off to apqci=on|off * Misc. minor changes Tony Krowiak (6): linux-headers: linux header updates for AP support s390x/ap: base Adjunct Processor (AP) object s390x/cpumodel: Set up CPU model for AP device support s390x/vfio: ap: Introduce VFIO AP device s390: doc: detailed specifications for AP virtualization MAINTAINERS: add entries for AP MAINTAINERS | 14 + default-configs/s390x-softmmu.mak | 1 + docs/vfio-ap.txt | 649 +++++++++++++++++++++++++++++++++++++ hw/s390x/Makefile.objs | 1 + hw/s390x/ap-device.c | 39 +++ hw/vfio/Makefile.objs | 1 + hw/vfio/ap.c | 182 +++++++++++ include/hw/s390x/ap-device.h | 38 +++ include/hw/vfio/vfio-common.h | 1 + linux-headers/asm-s390/kvm.h | 2 + linux-headers/linux/vfio.h | 2 + target/s390x/cpu_features.c | 3 + target/s390x/cpu_features_def.h | 3 + target/s390x/cpu_models.c | 2 + target/s390x/gen-features.c | 3 + target/s390x/kvm.c | 1 + 16 files changed, 942 insertions(+), 0 deletions(-) create mode 100644 docs/vfio-ap.txt create mode 100644 hw/s390x/ap-device.c create mode 100644 hw/vfio/ap.c create mode 100644 include/hw/s390x/ap-device.h
