NuttX system load
Hi Folks,
What is an easy way to compute the system load on Nutt-X?
I don't need the procinfo (Unix LA) just current CPU load and
optimally, I would like a measure 0-1000 where I can get 4 digits of
precision ...
The simpler the better, doesn't need to be a lot of code, only used
for a "busy-ness" factor.
Thank you very much!
-James

Dave Marples was using Orbuculum with some success in the past:

I added this feature a few years ago, but it seems it has since succumb to bit rot and perhaps a few too many fat fingers…
Take a look at the earliest to procfs.c and look for “/proc/load” or “/proc/cpuload”, I don’t recall…
