This is version six of the VFIO support in kvmtool. It addresses Will's comments for v5. Implement vfio-pci support in kvmtool. Devices are assigned to the guest by passing "--vfio-pci [domain:]bus:dev.fn" to lkvm run, after having bound the device to the VFIO driver (see Documentation/vfio.txt) This time around I also tested assignment of the x540 NIC on my old x86 desktop as well (previously only on AMD Seattle, an arm64 host). It worked smoothly. v6: git://linux-arm.org/kvmtool-jpb.git vfio/v6 v5: https://www.spinics.net/lists/kvm/msg166119.html Jean-Philippe Brucker (13): pci: add config operations callbacks on the PCI header pci: allow to specify IRQ type for PCI devices irq: add irqfd helpers Extend memory bank API with memory types pci: add capability helpers Import VFIO headers Add fls_long and roundup_pow_of_two helpers Add PCI device passthrough using VFIO vfio-pci: add MSI-X support vfio-pci: add MSI support vfio: Support non-mmappable regions Introduce reserved memory regions vfio: check reserved regions before mapping DMA Makefile | 2 + arm/gic.c | 76 ++- arm/include/arm-common/gic.h | 6 + arm/kvm.c | 2 +- arm/pci.c | 4 +- builtin-run.c | 5 + hw/pci-shmem.c | 12 +- hw/vesa.c | 2 +- include/kvm/irq.h | 17 + include/kvm/kvm-config.h | 3 + include/kvm/kvm.h | 54 +- include/kvm/pci.h | 118 +++- include/kvm/util.h | 14 + include/kvm/vfio.h | 127 ++++ include/linux/vfio.h | 719 ++++++++++++++++++++ irq.c | 31 + kvm.c | 99 ++- mips/kvm.c | 6 +- pci.c | 105 +-- powerpc/kvm.c | 2 +- vfio/core.c | 676 +++++++++++++++++++ vfio/pci.c | 1193 ++++++++++++++++++++++++++++++++++ virtio/net.c | 9 +- virtio/scsi.c | 10 +- x86/kvm.c | 6 +- 25 files changed, 3175 insertions(+), 123 deletions(-) create mode 100644 include/kvm/vfio.h create mode 100644 include/linux/vfio.h create mode 100644 vfio/core.c create mode 100644 vfio/pci.c -- 2.17.0
