let me try cover your last 2 messages in one
Let me see if I get your proposal right: -compile a new kernel with softdog and wd1100 as modules
right
-load one of the drivers somewhere in the boot process (and store them in one of the lrps)
I believe we identified modules.lrp as the best place, but then ... see below
That always imply a change in the base line, because the softdog module needs to get loaded somewhere (and must be available). Or did I get your proposal wrong?
Well, my original idea was to make /etc/init.d/watchdog aware of the underlying watchdog driver.
Maybe it's easier to have one patch which both add the driver and the necessary Config.in entries in the kernel source.
I had this before, however, I wanted to keep the structure the way Mark had it when he published his driver, so I could just send him the updated source to publish.
If this is something you would like to have it can be easily provided.

Will that generate warnings or errors?
lets ask the system.....
wrap: -root- # echo 1 > /proc/sys/dev/wd/graceful cannot create /proc/sys/dev/wd/graceful: directory nonexistent
I'm asking, because I want to understand the impact of adding wd1100 to the base-line.
That is clear, such aspects have to be considered.
This is what my /etc/init.d/watchdog looks like:
.....
case "$1" in
start)
CPUINFO=`grep "Geode by NSC" /proc/cpuinfo`
if [ "$CPUINFO" ] # this is a SC1100
then
insmod wd1100
echo 0 > /proc/sys/dev/wd/graceful
echo 20 > /proc/sys/dev/wd/timeout
else
insmod softdog
fi
.....
the rest is unmodified.Thanks for your time. Erich
