This series adds IRQ forwarding support in the VFIO platform device. The VFIO platform device uses the KVM-VFIO device to enable IRQ forwarding. Dependency List: - QEMU KVM platform device passthrough and its dependencies see https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg04379.html - kernel forwarding series: see (https://www.mail-archive.com/kvm@xxxxxxxxxxxxxxx/msg115253.html) Repos: - QEMU pieces can be found at: http://git.linaro.org/people/eric.auger/qemu.git (branch vfio_integ_v15_fwd) - kernel pieces can be found at: http://git.linaro.org/people/eric.auger/linux.git (branch 4.1-rc1_forward) The patch series was tested on Calxeda Midway (ARMv7) where one xgmac is assigned to KVM host while the second one is assigned to the guest. Reworked PCI device is not tested. Wiki for Calxeda Midway setup: https://wiki.linaro.org/LEG/Engineering/Virtualization/Platform_Device_Passthrough_on_Midway History: v1 -> v2: - update following x introduction of kvm qemu_irq/gsi hash table x new irq connect notifier x 2 stage eventfd/irqfd setup which complexifies irq forwarding setup v1: - that code originally was in KVM platform device passthrough series (v8), now moved in a separate RFC since dependent on many RFCs.
