Subject: watchdoug group ping
Date: Wed, 20 Apr 2016 09:10:52 +0200 [thread overview]
Message-ID: <57172B7C.4060407@de.bosch.com> (raw)
Hallo all,
my target is to provide pretimout support for devices which do not have
this functionality.
Pre-requirement is this patchset (i contacted the author to rebase it
against latest watchdog core branch):
https://www.mail-archive.com/linux-watchdog@vger.kernel.org/msg02394.html
The idea is to use different watchdogs/timers or what ever as one group
- one virtual device.
One driver will be responsible for reseting the system, other for
generating an interrupt on pre-timout.
It can be also useful for systems which require redundant watchdogs -
two or more watchdog pinged over one /dev/watchdog
I assume i would need to create a master virtual watchdog driver to
bypass/broadcast all pings to child devices.
Do you have some ideas or suggestions?
