Struct El1PhysicalTimer 

pub struct El1PhysicalTimer(/* private fields */);

Represents our Physical Timer when we are running at EL1.

Implementations

impl El1PhysicalTimer

pub unsafe fn new() -> El1PhysicalTimer

Create an EL1 Generic Timer handle

Safety

Only create one of these at any given time, as they access shared mutable state within the processor and do read-modify-writes on that state.

pub fn el0_access_physical_counter(&mut self, access: bool)

Control whether user code at EL0 can access the physical counter.

pub fn el0_access_physical_timer(&mut self, access: bool)

Control whether user code at EL0 can access the physical timer.
