Module acpi::mcfg [−][src]
Structs
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).
