Module acpi::mcfg

Structs

• Mcfg
• McfgEntry
• PciConfigEntry
  Configuration entry describing a valid bus range for the given PCI segment group.
• PciConfigEntryIterator
  Iterator providing a PciConfigEntry for all of the valid bus ranges on the system.
• PciConfigRegions
  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).
