[−][src]Struct sunrise_kernel::devices::pic::InternalPic

struct InternalPic {
    port_cmd: Pio<u8>,
    port_data: Pio<u8>,
}
[−]

A single PIC8259 device.

Fields

port_cmd: Pio<u8>
[−]

The PIC's COMMAND IO port.

port_data: Pio<u8>
[−]

The PIC's DATA IO port.

Implementations

impl InternalPic[src][−]

unsafe fn new(port_base: u16, is_master: bool, vector_offset: u8) -> InternalPic[src][−]

Setup the 8259 pic. Redirect the IRQ to the chosen interrupt vector.

Safety

The port should map to a proper PIC device. Sending invalid data to a random device can lead to memory unsafety. Furthermore, care should be taken not to share the underlying Pio.

pub fn acknowledge(&mut self)[src][−]

Acknowledges an IRQ, allowing the PIC to send a new IRQ on the next cycle.

pub fn mask(&mut self, irq: u8)[src][−]

Mask the given IRQ

pub fn unmask(&mut self, irq: u8)[src][−]

Unmask the given IRQ

pub fn get_mask(&self) -> u8[src][−]

Read the IRQ mask. Used mostly for debug purposes.
