[Qemu-devel] [PATCH v3 0/3] usb, xen: add pvUSB backend |

This series adds a Xen pvUSB backend driver to qemu. USB devices
connected to the host can be passed through to a Xen guest. The
devices are specified via Xenstore. Access to the devices is done
via host-libusb.c
I've tested the backend with various USB devices (memory sticks,
keyboard, ...).
Changes in V3:
- added new patch 2 (was sent formerly on it's own)
- patch 3 (was 2): multiple small changes as requested by Anthony Perard
- patch 3 (was 2): check for full ring in case of hotplug events as
requested by Anthony Perard
- patch 3 (was 2): use RING_COPY_REQUEST() instead of RING_GET_REQUEST()
- patch 3 (was 2): add check for required header version and disable
backend in case header is too old
Changes in V2:
- rebased to current qemu master
- removed support for isoc requests in this series, as the optimal way to
support those isn't clear yet. Will be added in a followup series.
- several changes as requested by Stefano Stabellini and Konrad Wilk
Changes since RFC:
- open device via qdev_device_add(), making patch 1 obsolete
- modify patch 2 to use isoc passthrough via libusb instead of one
job per frame
Juergen Gross (3):
xen: introduce dummy system device
xen: write information about supported backends
xen: add pvUSB backend
