PWDOG(4) Device Drivers Manual PWDOG(4) NAME pwdog - Quancom PWDOG1 watchdog timer device SYNOPSIS pwdog0 at pci? DESCRIPTION The pwdog driver provides support for Quancom PWDOG1 boards. If the kernel crashes, the watchdog timer is not reset and the system will reboot (assuming a proper connection is made between the PWDOG1 and the motherboard). Alternatively, the watchdog can be reinitialized via a userland process which ensures that process scheduling, not just kernel timeout processing, is still taking place. The timeout period of the PWDOG1 card is set using DIP switches and cannot be changed by software. SEE ALSO intro(4), pci(4) HISTORY The pwdog driver first appeared in OpenBSD 4.1 and NetBSD 6.0. AUTHORS The pwdog driver was written by Marc Balmer <mbalmer@NetBSD.org>. NetBSD 8.0 August 11, 2011 NetBSD 8.0
