This series adds XEN guest pvUSB support. With pvUSB it is possible to use physical USB devices from a XEN domain.
The support consists of a frontend in the unprivileged domU passing I/O-requests to the backend in a driver domain (usually Dom0). The backend is not part of this patch series, as it will be supported via qemu. The code is taken (and adapted) from the original pvUSB implementation done for Linux 2.6 in 2008 by Fujitsu. Normal operation of USB devices by adding and removing them dynamically to/from a domain has been tested using various USB devices (USB 1.1, 2.0 and 3.0). The pvUSB backend for these tests was a SUSE SLES Dom0 with a kernel based backend driver. Changes since V1: - removed backend, as it can be implemented in user land - added some access macros and definitions to the pvUSB interface description to make it independant from linux kernel USB internals - adapted frontend to newer kernel version and use new pvUSB interface macros - set port status in one chunk as suggested by Oliver Neukum Juergen Gross (3): usb: Add Xen pvUSB protocol description usb: Introduce Xen pvUSB frontend xen: add Xen pvUSB maintainer MAINTAINERS | 8 + drivers/usb/Kconfig | 2 + drivers/usb/Makefile | 2 + drivers/usb/xen/Kconfig | 10 + drivers/usb/xen/Makefile | 5 + drivers/usb/xen/xen-usbfront.c | 1647 ++++++++++++++++++++++++++++++++++++++ include/xen/interface/io/usbif.h | 252 ++++++ 7 files changed, 1926 insertions(+) create mode 100644 drivers/usb/xen/Kconfig create mode 100644 drivers/usb/xen/Makefile create mode 100644 drivers/usb/xen/xen-usbfront.c create mode 100644 include/xen/interface/io/usbif.h -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
