WatchDog Module Parameters
==========================

This file provides information on the module parameters of many of
the Linux watchdog drivers.  Watchdog driver parameter specs should
be listed here unless the driver has its own driver-specific information
file.

See Documentation/admin-guide/kernel-parameters.rst for information on
providing kernel parameters for builtin drivers versus loadable
modules.

-------------------------------------------------

watchdog core:
    open_timeout:
	Maximum time, in seconds, for which the watchdog framework will take
	care of pinging a running hardware watchdog until userspace opens the
	corresponding /dev/watchdogN device. A value of 0 means an infinite
	timeout. Setting this to a non-zero value can be useful to ensure that
	either userspace comes up properly, or the board gets reset and allows
	fallback logic in the bootloader to try something else.
