The communication is all done via the pvUSB backend in a driver domain (usually Dom0) which is owner of the physical device. The pvUSB frontend is a USB hcd for a virtual USB host connector. The code is taken from the pvUSB implementation in Xen done by Fujitsu based on Linux kernel 2.6.18. Changes from the original version are: - port to upstream kernel - put all code in just one source file - move module to appropriate location in kernel tree - adapt to Linux style guide - minor code modifications to increase readability Signed-off-by: Juergen Gross <jgross@xxxxxxxx> --- drivers/usb/host/Kconfig | 11 + drivers/usb/host/Makefile | 1 + drivers/usb/host/xen-hcd.c | 1606 ++++++++++++++++++++++++++++++++++++ 3 files changed, 1618 insertions(+) create mode 100644 drivers/usb/host/xen-hcd.cThis looks sane to me, but I don't know the HCD interface as well as others on linux-usb do, like Alan Stern. What tree do you want this to be merged through, my USB one?
Either that, or I can carry it through the Xen tree. Its your choice. :-) Juergen
