How does the /dev/watchdog timer exactly work? I found a description here and it says that once I open the file from an application I need to
update it every 10 seconds. I was wondering is this a hard limit? For example what if I update it in 11 seconds for instance?
Could someone explain the behavior to me please?
Because there are no "hard limits" in the thread scheduling so that I am certain that the file is updated in exactly 10 sec. stricty unless I use e.g. a spin loop instead of a sleep
