PCIAddress inforfation is obtained via SetupApi, which provides the information about address, bus, etc. We look throught entire device tree in the system and try to find device object for given volume. For this PDO SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration for a given devicei if it is possible. This is the most convinient way for a userspace service. The lookup is performed for every volume available. However, this information is not mandatory for vss-provider. In order to use SetupApi we need to notify linker about it. We do not need to install additional libs, so we do not make separate configuration option to use libsetupapi.su SetupApi gives as the same information as kernel driver with IRP_MN_QUERY_INTERFACE. https://support.microsoft.com/en-us/kb/253232 Signed-off-by: Olga Krishtal <okrishtal@virtuozzo.com> Signed-off-by: Denis V.
