[−][src]Struct acpi::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).
Implementations
impl PciConfigRegions[src]
pub fn new<H>(tables: &AcpiTables<H>) -> Result<PciConfigRegions, AcpiError> where
H: AcpiHandler, [src]
H: AcpiHandler,
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 PCIe device
function. Returns None if there isn't an entry in the MCFG that manages that device.
