Almost all consumer motherboards have a chipset with embedded hardware watchdog that's well supported by respective drivers in FreeBSD / Linux / etc. Some vendors like Intel may lock down that functionality, but most (Asus, Gigabyte, etc) don't.
- NelsonMinar 7y agoDo you have any more info on that chipset watchdog and how I'd use it in Linux? Is it this, the TCO Watchdog? http://www.madore.org/~david/linux/iTCO-wdt-test.html http://www.madore.org/~david/linux/iTCO-wdt-test.html
- agapon 7y agoYes, iTCO_wdt is for Intel chipsets; sp5100_tco is for AMD chipsets (including FCH). The names are a bit weird to my taste. FreeBSD ones sound a little bit better (but maybe I am just more used to them): ichwd (ICH WD) and amdsbwd (AMD SouthBridge WD).
- NelsonMinar 7y agoThanks! I somehow spent several hours researching how to run watchdogs on Linux without finding this. Seems like exactly what I need. While I'm here, systemd's watchdog docs are also pretty good: http://0pointer.de/blog/projects/watchdog.html http://0pointer.de/blog/projects/watchdog.html
