hw/vfio/Makefile.objs: Create new CONFIG_* variables for VFIO core and PCI Make hw/vfio configurable and add new CONFIG_VFIO_* to the default-configs/s390x*-softmmu.mak. This allow a finer-grain selection of the various VFIO backends.

vfio/ccw: vfio based subchannel passthrough driver We use the IOMMU_TYPE1 of VFIO to realize the subchannels passthrough, implement a vfio based subchannels passthrough driver called "vfio-ccw". Support qemu parameters in the style of: "-device vfio-ccw,sysfsdev=$mdev_file_path,devno=xx.x.xxxx' Reviewed-by: Eric Auger <eric.auger@redhat.com> Acked-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Xiao Feng Ren <renxiaof@linux.vnet.ibm.com> Signed-off-by: Dong Jia Shi <bjsdjshi@linux.vnet.ibm.com> Message-Id: <20170517004813.58227-8-bjsdjshi@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>

hw/vfio: Add CONFIG switches for calxeda-xgmac and amd-xgbe Both devices seem to be specific to the ARM platform. It's confusing for the users if they show up on other target architectures, too (e.g. when the user runs QEMU with "-device ?" to get a list of supported devices). Thus let's introduce proper configuration switches so that the devices are only compiled and included when they are really required.

s390x/vfio: ap: Introduce VFIO AP device Introduces a VFIO based AP device. The device is defined via the QEMU command line by specifying: -device vfio-ap,sysfsdev=<path-to-mediated-matrix-device> There may be only one vfio-ap device configured for a guest. The mediated matrix device is created by the VFIO AP device driver by writing a UUID to a sysfs attribute file (see docs/vfio-ap.txt). The mediated matrix device will be named after the UUID. Symbolic links to the $uuid are created in many places, so the path to the mediated matrix device $uuid can be specified in any of the following ways: /sys/devices/vfio_ap/matrix/$uuid /sys/devices/vfio_ap/matrix/mdev_supported_types/vfio_ap-passthrough/devices/$uuid /sys/bus/mdev/devices/$uuid /sys/bus/mdev/drivers/vfio_mdev/$uuid When the vfio-ap device is realized, it acquires and opens the VFIO iommu group to which the mediated matrix device is bound. This causes a VFIO group notification event to be signaled. The vfio_ap device driver's group notification handler will get called at which time the device driver will configure the the AP devices to which the guest will be granted access.

hw/vfio: Move the IGD quirk code to a separate file The IGD quirk code defines a separate device, the so-called "vfio-pci-igd-lpc-bridge" which shows up as a user-creatable device in all QEMU binaries that include the vfio code. This is a little bit unfortunate for two reasons: First, this device is completely useless in binaries like qemu-system-s390x. Second we also would like to disable it in downstream RHEL which currently requires some extra patches there since the device does not have a proper Kconfig-style switch yet. So it would be good if the device could be disabled more easily, thus let's move the code to a separate file instead and introduce a proper Kconfig switch for it which gets only enabled by default if we also have CONFIG_PC_PCI enabled.
