Greetings
On a 2.4.22 kernel running on an 8xx CPU, I'm trying to find useful
static kernel memory locations that will help diagnose problems after a
crash has occured.
So far I have identified load averages, uptime, active & inactive memory
and interrupt counts and I can dump these out from the bootloader.
What I'd really like is the pid of the current task but I can't find it
as the current task structure pointer is held in a register (r2) and
hence is not available after a reset.
Any clues as to where I could find this information?
