Struct PciBus 

pub struct PciBus {
    ecam_base: usize,
    ecam_size: usize,
    devices: Mutex<Vec<PciDeviceInfo>>,
}

PCI bus manager

Manages PCI device discovery and configuration space access.

Fields

ecam_base: usize

ECAM (Enhanced Configuration Access Mechanism) base address

ecam_size: usize

ECAM region size in bytes

devices: Mutex<Vec<PciDeviceInfo>>

List of discovered PCI devices

Implementations

impl PciBus

pub fn scan(&self)

Scan the PCI bus and discover all devices

This is a convenience method that creates a scanner and performs the scan, storing discovered devices in the bus manager.

pub fn scan_and_register(&self)

Scan the PCI bus and register devices with the DeviceManager

This scans for PCI devices and registers them with the global device manager so they can be matched with drivers.

impl PciBus

pub const fn new(ecam_base: usize, ecam_size: usize) -> Self

Create a new PCI bus manager

Arguments

• ecam_base - Physical address of the ECAM region
• ecam_size - Size of the ECAM region in bytes

Returns

A new PciBus instance

pub const fn ecam_base(&self) -> usize

Get the ECAM base address

pub const fn ecam_size(&self) -> usize

Get the ECAM size

pub fn is_valid_address(&self, addr: &PciAddress) -> bool

Check if a PCI address is within the ECAM region

pub fn devices(&self) -> Vec<PciDeviceInfo>

Get the list of discovered devices

pub fn add_device(&self, device: PciDeviceInfo)

Add a device to the list of discovered devices
