  • 985c0679d   arm64: Generic timers support ... Browse Code ยป

    This patch adds support for the ARM generic timers with A64 instructions
    for accessing the timer registers. It uses the physical counter as the
    clock source and the virtual counter as sched_clock.

    The timer frequency can be specified via DT or read from the CNTFRQ_EL0
    register. The physical counter is also accessible from user space
    allowing fast gettimeofday() implementation.
