Struct PciScanner 

pub struct PciScanner<'a> {
    config: PciConfig,
    bus: &'a PciBus,
}

PCI scanner

Handles scanning the PCI bus tree to discover devices.

Fields

config: PciConfig

PCI configuration space accessor

bus: &'a PciBus

Bus manager reference

Implementations

impl<'a> PciScanner<'a>

pub fn new(bus: &'a PciBus) -> Self

Create a new PCI scanner

Arguments

• bus - Reference to the PCI bus manager

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

Scan the entire PCI bus tree

This scans all possible bus/device/function combinations and discovers present devices.

Returns

Vector of discovered PCI devices

fn scan_bus( &self, bus: u8, devices: &mut Vec<PciDeviceInfo>, id_counter: &mut usize, )

Scan a single PCI bus

fn scan_device( &self, bus: u8, device: u8, devices: &mut Vec<PciDeviceInfo>, id_counter: &mut usize, )

Scan a single PCI device

fn probe_function( &self, bus: u8, device: u8, function: u8, id_counter: &mut usize, ) -> Option<PciDeviceInfo>

Probe a specific PCI function

fn generate_device_name( _vendor_id: u16, _device_id: u16, _bus: u8, _device: u8, _function: u8, ) -> &'static str

Generate a device name from vendor and device IDs

This is a simplified implementation. A real implementation would maintain a static string pool or use a more sophisticated naming scheme.
