Juergen Gross	494ed3997d	usb: Introduce Xen pvUSB frontend (xen hcd) ... Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen domU to communicate with a USB device assigned to that domU. 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@suse.com> Link: https://lore.kernel.org/r/20211123132048.5335-3-jgross@suse.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2021-12-13 14:58:32 +01:00
