I've asked whether Mr. Sander wouldn't mind chiming in and he said he would gladly add 'Tested-by: Sander Eikelenboom ' to the patches. I haven't asked Mr. Albert since he is busy making his set of patches for the Wii controller ready. Mr. Sander's long summary (a bit of explanation here: these five patches form the basis of a branch that has Xen PCI frontend driver allowing PCI passthrough, so his testing encompassed these five and many more): "If have placed the usb controller in another system now. So it's tested with: Intel system, usb 3.0 xhci PCIe host controller: - Xen-4.0.0rc6, dom0 xen-next, domU your 2.6.33 tree i mentioned - Baremetal on this system with the 2.6.33 from your tree AMD system (running now, no iommu in this system): passthrough of USB2.0 PCI host controller, USB2.0 PCIe hostcontroller, USB 3.0 +PCIe host controller, 1 usb videograbber per usb controller. - Xen-4.0.0rc6, dom0 2.6.31.12 pvops kernel from jeremy's tree, domU your 2.6.33 tree i mentioned All(with xen and baremetal) have been tested by grabbing raw or mpeg2 video streams to v4l usb capture devices. So a 'Tested-by' seems to be justified i would say" The git branch in question is pv/merge.2.6.33 from GIT tree: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
