Hi, >I'm currently developing a driver for this watchdog-card: > 'Antrax WatchCard PCI' -> http://www.antrax.de/ (German) >(btw. Antrax != Anthrax) > >And now I have some questions: > >- Should I develop the driver for 4.x or 5.x or both? Cool ! That depends where do you plan to use it. I suppose that you only develop a 5.x version if you don't need to run it yourself on 4.x >- What would be the preferred method for configuring and handling the card? > a: using a kernel module for triggering and sysctl for config? > (this method is preferred by me) > b: a daemon that handles all of that? > c: a tool which could be run by cron or the like? a of course. b and c don't make any sense, only for debugging purposes of the saved memory, see below. >- Are there any quirks I should take care of? > > The card uses a PITA-2 (PSB4610) from Infineon as PCI-Controller and has an > optional sensor for system temperature. >From the documentation: ># the last state of the main program (kernel) before the watchdog card > triggered is saved on the card and can be read after booting.

A tool to debug these would be neat here ... Or a sysctl to read the latter ...
