Struct KeyboardController

pub struct KeyboardController {
    keystate: KeyState,
    gather: AtomicU32,
    cport: IOPort,
    dport: IOPort,
}

Fields

keystate: KeyState

gather: AtomicU32

gather require synchronization between L2 and L3, therefore we pack the Key into a u32 and use an Atomic type here.

cport: IOPort

dport: IOPort

Implementations

impl KeyboardController

pub const fn new() -> Self

fn toggle_lock(&mut self, lock: Modifiers)

fn update_led(&self)

in some corner cases, e.g. keyboard control I/O may fail, while the CAPSLOCK is set and the uppcase table is used for key decoding. So we never set the leds explicitly, instead we update the leds from the current keyboard state i.e. keystate.modi

fn update_state(&mut self, code: u8)

fn press_event(&mut self) -> bool

fn release_event(&mut self)

fn read_status(&self) -> Option<StatusReg>

fn fetch_key(&mut self)

fn consume_key(&mut self) -> Option<Key>

this is safe to be called from all sync levels

fn decode_key(&mut self)

fn cycle_repeat_rate()

fn cycle_deley()

unsafe fn __block_until_cmd_buffer_empty(&self)

unsafe fn __block_until_data_available(&self)

block until there is something in the data register to read

impl KeyboardController

fn disable_keyboard_int()

fn enable_keyboard_int()

fn is_int_masked() -> bool

impl KeyboardController

pub unsafe fn reboot(&self)
