These patches implements a separate module for hostdev passthrough so that it could be shared by different drivers and can maintain a global state of a host device.
patch 1/6: extract hostdev passthrough function from qemu_hostdev.c and make it reusable by multiple drivers. patch 2/6: add a unit test for hostdev common library. patch 3/6: switch qemu driver to use the common library instead of its own hostdev passthrough APIs. patch 4/6: switch lxc driver to use the common library instead of its own hostdev passthrough APIs. patch 5/6: add a hostdev pci backend type for xen usage. patch 6/6: add pci passthrough to libxl driver.
Thanks for addressing my comments from V10. Any objections to applying this series now? hostdev passthrough is long overdue in the libxl driver :).
Since this is replacing the existing pci passthrough code in both the lxc and qemu drivers, I think we need both a line-for line comparison and some real test time. I can do the code audit and some amount of testing for qemu, but may be out of commission for the next 3 days. I'm not sure about lxc. I also agree that we really need to get this in, just so we can stop worrying about missing bugfixes that have been put into the qemu hostdev code.
