3.6.3.9. Generic Timer

The generic timer can schedule events and trigger interrupts that are based on an incrementing counter value. It generates timer events as active-low interrupt outputs and event streams.
The Cortex* -A55 core provides a set of timer registers. The timers are:
  • An EL1 Non-secure physical timer
  • An EL2 Hypervisor physical timer
  • An EL3 Secure physical timer
  • A virtual timer
  • A Hypervisor virtual timer
The Cortex* -A55 core does not include the system counter.
