func GetPCIeRootAttributeByPCIBusID ¶
func GetPCIeRootAttributeByPCIBusID(pciBusID string) (DeviceAttribute, error)
GetPCIeRootAttributeByPCIBusID retrieves the PCIe Root Complex for a given PCI Bus ID. in BDF (Bus-Device-Function) format, e.g., "0123:45:1e.7".
It returns a DeviceAttribute with the PCIe Root Complex information("pci<domain>:<bus>") as a string value or an error if the PCI Bus ID is invalid or the root complex cannot be determined.
