Re: [Crash-utility] Add an option "-c" for commamd runq
----- Original Message -----
Hello Dave,
The patch is used to improve the existing command, which adds an option "-c"
to the the command "runq". The option "-c" displays the timestamp
information about
the runqueue each of cpu. The timstamp information, which accordings to the kernel
version you use, may be the value of runqueue's member. for example, rq.clock or
rq.timestamp_last_tick, even runqueue.timestamp_last_tick.
Besides, I have already tested it on rhel4.8/rehl5.7/rhel6.2, without any error.
The result like this:
> crash> runq -c
> CPU 0: 66789719522523
> CPU 1: 66789719628339
> CPU 2: 66789719519625

Wei,
What is the debugging scenario that you feel the need to know the
timestamp of each cpu's runqueue? Perhaps you want to compare it to
the "ps -l" output?
