This patchset exploits the VFIO ZPCI CLP region, which provides hardware information about passed-through s390 PCI devices that can be shared with the guest. The retrieval of this information is done once per function (and for a subset of data, once per function group) and is performed at time of device plug. Some elements provided in the CLP region must still be forced to default values for now to reflect what QEMU actually provides support for. The original work for this feature was done by Pierre Morel. Associated kernel patchset: https://lkml.org/lkml/2020/10/2/981 Changes from v1: - Added 2 patches to the front of this set that move the s390-pci-bus.h and s390-pci-inst.h files to include + associated MAINTAINERS hit. These can be applied separately, but are included here for the sake of simplicity. - Patch 4: header update placeholder refreshed to rc7 - Patch 5: Move new s390-pci-clp.h to include folder - Patch 6+: s/grp/group/ and fallout from this - Patch 9: Move new s390-pci-vfio.h to include folder Matthew Rosato (6): s390x/pci: Move header files to include/hw/s390x MAINTAINERS: Update s390 PCI entry to include headers update-linux-headers: Add vfio_zdev.h linux-headers: update against 5.9-rc7 s390x/pci: clean up s390 PCI groups s390x/pci: get zPCI function info from host Pierre Morel (3): s390x/pci: create a header dedicated to PCI CLP s390x/pci: use a PCI Group structure s390x/pci: use a PCI Function structure MAINTAINERS | 1 + hw/s390x/meson.build | 1 + hw/s390x/s390-pci-bus.c | 86 ++++- hw/s390x/s390-pci-bus.h | 372 -------------------- hw/s390x/s390-pci-inst.c | 33 +- hw/s390x/s390-pci-inst.h | 312 ----------------- hw/s390x/s390-pci-vfio.c | 235 +++++++++++++ hw/s390x/s390-virtio-ccw.c | 2 +- include/hw/s390x/s390-pci-bus.h | 385 +++++++++++++++++++++ include/hw/s390x/s390-pci-clp.h | 215 ++++++++++++ include/hw/s390x/s390-pci-inst.h | 116 +++++++ include/hw/s390x/s390-pci-vfio.h | 19 + .../drivers/infiniband/hw/vmw_pvrdma/pvrdma_ring.h | 14 +- linux-headers/linux/kvm.h | 6 +- linux-headers/linux/vfio.h | 5 + scripts/update-linux-headers.sh | 2 +- 16 files changed, 1085 insertions(+), 719 deletions(-) delete mode 100644 hw/s390x/s390-pci-bus.h delete mode 100644 hw/s390x/s390-pci-inst.h create mode 100644 hw/s390x/s390-pci-vfio.c create mode 100644 include/hw/s390x/s390-pci-bus.h create mode 100644 include/hw/s390x/s390-pci-clp.h create mode 100644 include/hw/s390x/s390-pci-inst.h create mode 100644 include/hw/s390x/s390-pci-vfio.h -- 1.8.3.1
