Struct AhciController 

pub struct AhciController {
    abar_virt: u64,
    ports: Vec<AhciPort>,
}

Fields

abar_virt: u64

ports: Vec<AhciPort>

Implementations

impl AhciController

fn port_by_num(&self, port_num: u8) -> Option<&AhciPort>

pub unsafe fn init() -> Result<Self, AhciError>

Probe and initialise an AHCI controller from the PCI bus.

Safety

Must be called once during single-threaded kernel init (MMIO mapping).

pub fn sector_count(&self) -> u64

Return sector count of the first port.

pub fn first_port_num(&self) -> Option<u8>

Return the logical port number of the first usable port.

fn first_port(&self) -> Option<&AhciPort>

Performs the first port operation.

Reads sector.

fn write_sector(&self, sector: u64, buf: &[u8]) -> Result<(), BlockError>
