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.

The tcpcib driver first appeared in
OpenBSD 5.2.
The tcpcib driver was written by
Matt Dainty
<matt@bodgit-n-scarper.com>.
Apart from the core pcib(4) functionality, timecounter and the watchdog(4) interface, the driver doesn't support any other aspects of the hardware.
