tco
— Intel
Controller Hub TCO watchdog timer device
tco* at ichlpcib?
The tco
driver provides support for the
watchdog timer included in the Intel Controller Hub (ICH).
Setting the timer interval and arming the watchdog is performed using the wdogctl(8) utility. For ICH5 and earlier controllers, the interval is in the range of 2 to 23 seconds; for ICH6 and newer controllers, the interval is in the range of 1 to 367 seconds.
The tco
driver first appeared in
NetBSD 8.0. In earlier releases of
NetBSD the driver was included as part of the
x86/ichlpcib(4)
driver.
The tco
driver was written by
Minoura Makoto
<minoura@NetBSD.org>
and Matthew R. Green
<mrg@NetBSD.org>. The
tco
driver was separated from the
x86/ichlpcib(4)
driver by Paul Goyette
<pgoyette@NetBSD.org>.
