Structs
- Configuration entry describing a valid bus range for the given PCI segment group.
- Iterator providing a
PciConfigEntry
for all of the valid bus ranges on the system. - Describes a set of regions of physical memory used to access the PCIe configuration space. A region is created for each entry in the MCFG. Given the segment group, bus, device number, and function of a PCIe device, the
physical_address
method on this will give you the physical address of the start of that device function’s configuration space (each function has 4096 bytes of configuration space in PCIe).
