Implementations

impl BusSchemeServer

pub fn new(drivers: Vec<(String, Box<dyn BusDriver>)>, port_handle: u64) -> Self

Creates a new instance.

pub fn refresh_pci_cache(&mut self) -> Result<usize, ()>

Performs the refresh pci cache operation.

Returns Ok(count) with the number of devices found, or Err(()) if the underlying pci_enum syscall failed (cache remains unchanged).

fn ok_reply(sender: u64) -> IpcMessage

fn err_reply(sender: u64, code: usize) -> IpcMessage

fn alloc_id(&mut self) -> u64

fn resolve_driver_path<'a>(&self, path: &'a str) -> Option<(usize, &'a str)>

Split a normalised path into a driver index + sub-path, or detect PCI / root.

fn is_pci_path(path: &str) -> bool

fn path_exists(&self, path: &str) -> bool

fn parse_reg_offset(path: &str) -> Option<usize>

fn handle_open(&mut self, sender: u64, payload: &[u8]) -> IpcMessage

fn handle_read(&self, sender: u64, payload: &[u8]) -> IpcMessage

fn generate_read_content(&self, kind: &HandleKind, offset: usize) -> Vec<u8>

fn read_pci_content(&self, path: &str) -> Vec<u8>

fn read_driver_content( &self, driver: &Box<dyn BusDriver>, name: &str, sub_path: &str, ) -> Vec<u8>

fn handle_write(&mut self, sender: u64, payload: &[u8]) -> IpcMessage

fn handle_close(&mut self, sender: u64, payload: &[u8]) -> IpcMessage

fn handle_readdir(&self, sender: u64, payload: &[u8]) -> IpcMessage

pub fn serve(&mut self) -> !

Performs the serve operation.

fn normalize_path(path: &str) -> String

fn parse_hex_u8(s: &str) -> Option<u8>

fn parse_hex_u16(s: &str) -> Option<u16>

fn parse_pci_bdf(s: &str) -> Option<PciAddress>

fn parse_cfg_path(path: &str) -> Option<(PciAddress, u8, u8)>

fn parse_find_path(path: &str) -> Option<(u16, u16)>

fn render_inventory(&self) -> Vec<u8>
