96 * DESCRIPTION: This function derives a full PCI ID for a PCI device,
97 * consisting of a Segment number, Bus number, Device number,
98 * and function code.
99 *
100 * The PCI hardware dynamically configures PCI bus numbers
101 * depending on the bus topology discovered during system
102 * initialization. This function is invoked during configuration
103 * of a PCI_Config Operation Region in order to (possibly) update
104 * the Bus/Device/Function numbers in the pci_id with the actual
105 * values as determined by the hardware and operating system
106 * configuration.
107 *
108 * The pci_id parameter is initially populated during the Operation
109 * Region initialization. This function is then called, and is
110 * will make any necessary modifications to the Bus, Device, or
111 * Function number PCI ID subfields as appropriate for the
112 * current hardware and OS configuration.
113 *
114 * NOTE: Created 08/2010. Replaces the previous OSL acpi_os_derive_pci_id
115 * interface since this feature is OS-independent. This module
116 * specifically avoids any use of recursion by building a local
117 * temporary device list.
