tcpcib —
Intel Atom E600 series LPC bridge, timecounter and
watchdog timer
tcpcib* at pci?
isa* at tcpcib?
The
tcpcib driver provides support for the
Intel Atom E600 series LPC bridge and implements a 64-bit 14.3 MHz timecounter
using the HPET timer.
The
tcpcib driver also provides the standard
watchdog(4) interface to the
watchdog timer and may be used with
watchdogd(8). The watchdog
timer can be configured via
sysctl(8).
Once the watchdog timer resets the CPU, the driver reports it on the next boot
displaying the “reboot on timeout” message in the
dmesg(8).
The maximum timeout value supported by the watchdog timer is 600 seconds.

Apart from the core
pcib(4)
functionality, timecounter and the
watchdog(4) interface, the
driver doesn't support any other aspects of the hardware.
