OK, I got the driver for the pcengines wrap hardware running and can successfully reboot the system without the need of a keyboard controller. It requires a few quirks to Bering which I would like your comments on. I do not think this is too much of a deviation off the mainstream to deserve a new branch.
The pcengines wrap system does not have a keyboard controller, which in standard PC systems seems to be essential for the warm reboot. In order to have this functionality I slightly modified the wd1100 watchdog driver which handles the wrap`s Geode Processor's built in watchdog timer.
I removed softdog from the Bering kernel and made it a module, thus I was able to add the wd1100 driver as a module to the Bering kernel.
The wd1100 driver implements the devfs interface, so it is very easy to control its behaviour through the files it presents in /proc/sys/dev/wd.
The following is needed to set the wd1100 up for automatic reboot.
- insert the wd1100 module insmod wd1100
- set the wd1100 watchdog to reset when /usr/sbin/watchdog dies echo 0 > /proc/sys/dev/wd/graceful
- set the timeout to 2 times the value of the watchdog timer interval echo 20 > /proc/sys/dev/wd/timeout
These can go into /etc/init.d/watchdog.
Start /usr/sbin/watchdog, it will tickle the driver every 10 seconds.
In order to reboot the system all that is needed is to send a kill signal to the watchdog process, the rest is accomplished by the SC1100`s built in watchdog.
Jacques and KaPeKa, would you consider this to go into the main branch?
Thanks for comments.
