1 This file provides information on the module parameters of many of 2 the Linux watchdog drivers. Watchdog driver parameter specs should 3 be listed here unless the driver has its own driver-specific information 4 file. 5 6 7 See Documentation/admin-guide/kernel-parameters.rst for information on 8 providing kernel parameters for builtin drivers versus loadable 9 modules. 10 11 12 ------------------------------------------------- 13 acquirewdt: 14 wdt_stop: Acquire WDT 'stop' io port (default 0x43) 15 wdt_start: Acquire WDT 'start' io port (default 0x443) 16 nowayout: Watchdog cannot be stopped once started 17 (default=kernel config parameter) 18 ------------------------------------------------- 19 advantechwdt: 20 wdt_stop: Advantech WDT 'stop' io port (default 0x443) 21 wdt_start: Advantech WDT 'start' io port (default 0x443) 22 timeout: Watchdog timeout in seconds. 1<= timeout <=63, default=60. 23 nowayout: Watchdog cannot be stopped once started 24 (default=kernel config parameter) 25 ------------------------------------------------- 26 alim1535_wdt: 27 timeout: Watchdog timeout in seconds.
