Struct sunrise_kernel::devices::pit::PIT_PORTS

struct PIT_PORTS {
    __private_field: (),
}

The mutex wrapping the ports

Fields

__private_field: ()

Methods from Deref<Target = SpinLock<PITPorts>>

pub fn lock(&self) -> SpinLockGuard<T>

Locks the spinlock and returns a guard.

The returned value may be dereferenced for data access and the lock will be dropped when the guard falls out of scope.

Panics if called in an interrupt context.

let mylock = crate::sync::SpinLock::new(0);
{
    let mut data = mylock.lock();
    // The lock is now locked and the data can be accessed
    *data += 1;
    // The lock is implicitly dropped
}

pub unsafe fn force_unlock(&self)

Force unlock the spinlock. If the lock isn't held, this is a no-op.

Safety

This is extremely unsafe if the lock is not held by the current thread. However, this can be useful in some instances for exposing the lock to FFI that doesn't know how to deal with RAII.

pub fn try_lock(&self) -> Option<SpinLockGuard<T>>

Tries to lock the spinlock. If it is already locked, it will return None. Otherwise it returns a guard within Some.
