[−][src]Struct acpi::PciConfigRegions
Describes a set of regions of physical memory used to access the PCI-E configuration space. A
region is created for each entry in the MCFG. Given the segment group, bus, device number, and
function of a PCI-E 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 PCI-E).
Methods
impl PciConfigRegions[src]
pub fn physical_address(
&self,
segment_group_no: u16,
bus: u8,
device: u8,
function: u8
) -> Option<u64>[src]
&self,
segment_group_no: u16,
bus: u8,
device: u8,
function: u8
) -> Option<u64>
Get the physical address of the start of the configuration space for a given PCI-E device
function. Returns None if there isn't an entry in the MCFG that manages that device.
