Hi, This patch series adds virtio input devices. It's basically sending linux evdev events over virtio. There is support for emulated hid devices (i.e. send usual input to virtio device instead of usb or ps2 device).
For v4 I've splitted the patches, so virtio-*-device and virtio-*-pci are added by separate patches. I've also left out pass-through for now. So, patches 1-3 implement the actual devices, and they should be ready to merge. They apply cleanly to master and build just fine with a minor fixup (s/64/32/ for virtio_input_get_features). I plan to send out a pull request for them soon. Patches 4-6 carry the virtio-pci support code. They have a dependency on the virtio-1 branch (from mst or cordula), because I want them be non-transitional devices. The device has been designed with virtio-1 in mind, where virtio-pci config space moves from io to mmio, so having a bit larger config space isn't a big issue. Not sure how to proceed best with patches 4-6. I don't feel like making them transitional devices, but missing qemu 2.4 because virtio-pci isn't ready for virtio 1.0 doesn't look nice either :( Guest driver: Present in linux kernel 4.1-rc1 & newer.
