Function hal_x86_64::cpu::wait_for_interrupt
source · pub fn wait_for_interrupt()
Expand description
Wait for an interrupt in a spin loop.
This is distinct from core::hint::spin_loop
, as it is intended
specifically for waiting for an interrupt, rather than progress from another
thread. This should be called on each iteration of a loop that waits on a condition
set by an interrupt handler.
This function will execute one intrinsics::sti
instruction to enable interrupts
followed by one intrinsics::hlt
instruction to halt the CPU.
