Hi,
is there a specific reason that the timeout in the linux watchdog drivers is
only provided in seconds resolution? What about timeouts in ms area/precision?
The question would probably be why not. On a loaded system, sub-second
watchdog timeouts are quite unreasonable.
In other words, you would have to provide a very good argument for
sub-second timeouts if you see the need for it. That some hardware
may require it is not really an argument here - this is all about
user space - kernel interface, not about limitations of specific
hardware.
