ATRTC(4)                 BSD Kernel Interfaces Manual                 ATRTC(4)

NAME
     atrtc — AT Real-Time Clock (RTC) driver

SYNOPSIS
     This driver is a mandatory part of i386/amd64 kernels.

     The following tunables are settable from the loader(8):

     hint.atrtc.X.clock
     controls event timers functionality support.  Setting to 0, disables it.
     Default value is 1.

     hw.atrtc.enable
     Forces enabling or disabling of the device(s).  Setting to 0 disables it,
     setting to 1 enables it, bypassing any platform configuration hints.
     Default value is -1 (autodetect).

DESCRIPTION
     This driver uses RTC hardware to supply kernel with time-of-day clock
     with 1 second resolution and one event timer.  This hardware uses base
     frequency of 32768Hz for advancing time-of-day clock and generating peri‐
     odic interrupts.  Interrupts could be generated with fixed number of fre‐
     quencies, from 2Hz to 8192Hz, obtained by dividing base frequency by one
     of supported power-of-2 divisors.

     Event timer provided by the driver is irrelevant to CPU power states.
