2012-05-30xen/pci: Check for PCI bridge before using it.Zhang, Yang Z
Some SR-IOV devices may use more than one bus number, but there is no real bridges because that have internal routing mechanism. So need to check whether the bridge is existing before using it.

2011-09-22xen/pci: support multi-segment systemsJan Beulich
Now that the hypercall interface changes are in -unstable, make the kernel side code not ignore the segment (aka domain) number anymore (which results in pretty odd behavior on such systems). Rather, if only the old interfaces are available, don't call them for devices on non-zero segments at all.

2011-08-26xen/pci: make bus notifier handler return sane valuesJan Beulich
Notifier functions are expected to return NOTIFY_* codes, not -E... ones. In particular, since the respective hypercalls failing is not fatal to the operation of the Dom0 kernel, it must be avoided to return negative values here as those would make it appear as if NOTIFY_STOP_MASK wa set, suppressing further notification calls to other interested parties (which is also why we don't want to use notifier_from_errno() here). While at it, also notify the user of a failed hypercall.

2010-10-27xen: register xen pci notifierWeidong Han
Register a pci notifier to add (or remove) pci devices to Xen via hypercalls. Xen needs to know the pci devices present in the system to handle pci passthrough and even MSI remapping in the initial domain.
