Next version, not so many changes from v3. As you might have guessed, the goals are still the same: - Being able to disable PCI support in a build completely. - Properly fencing off PCI if the relevant facility bit is not provided.
Changes v3->v4: - introduce pci_available boolean - use pci_available to fence off setting the zcpi facility bit - collected tags Branch is still git://github.com/cohuck/qemu no-zpci-cpumodel Cornelia Huck (9): kvm: remove hard dependency on pci s390x/pci: add stubs s390x: chsc nt2 events are pci-only s390x/pci: do not advertise pci on non-pci builds s390x/ccw: create s390 phb conditionally s390x/sclp: properly guard pci-specific functions s390x/pci: fence off instructions for non-pci s390x/kvm: msi route fixup for non-pci s390x: refine pci dependencies accel/kvm/kvm-all.c | 6 ++-- default-configs/s390x-softmmu.mak | 2 +- hw/pci/pci-stub.c | 13 +++++++ hw/pci/pci.c | 2 ++ hw/s390x/Makefile.objs | 3 +- hw/s390x/s390-pci-bus.c | 4 +-- hw/s390x/s390-pci-bus.h | 4 +-- hw/s390x/s390-pci-stub.c | 74 +++++++++++++++++++++++++++++++++++++++ hw/s390x/s390-virtio-ccw.c | 12 ++++--- hw/s390x/sclp.c | 19 +++++++--- include/hw/pci/pci.h | 2 ++ target/s390x/ioinst.c | 16 +++++++++ target/s390x/kvm.c | 64 +++++++++++++++++++++++++-------- 13 files changed, 189 insertions(+), 32 deletions(-) create mode 100644 hw/s390x/s390-pci-stub.c -- 2.13.3
