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/kernel-parameters.txt for information on providing kernel parameters for builtin drivers versus loadable modules. ------------------------------------------------- acquirewdt: wdt_stop: Acquire WDT 'stop' io port (default 0x43) wdt_start: Acquire WDT 'start' io port (default 0x443) nowayout: Watchdog cannot be stopped once started (default=kernel config parameter) ------------------------------------------------- advantechwdt: wdt_stop: Advantech WDT 'stop' io port (default 0x443) wdt_start: Advantech WDT 'start' io port (default 0x443) timeout: Watchdog timeout in seconds. 1<= timeout <=63, default=60. nowayout: Watchdog cannot be stopped once started (default=kernel config parameter) ------------------------------------------------- alim1535_wdt: timeout: Watchdog timeout in seconds.
