The attached patches allow the pciback module to perform a reset whenever a PCI device is: - attached to the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/bind - detached from the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/unbind - and when the guest is done with (internally when the guest is not using

First, maintainer''s addresses (Ryan Wilson <hap9@epoch.ncsc.mil>, Chris Bookholt <hap10@epoch.ncsc.mil>) are wrong (users unknown to remote mailsystem), so posting to you: PCI bus format strings are wrong. "%04x:%02x:%02x.%d" should be used instead of "%04x:%02x:%02x.%1x" (in many places of linux+v3.2.1/drivers/xen/xen-pciback/pci_stub.c) --
