a good idea. I think that it´s not enough for me schedstats, because I
want to make a visual scheduler, I mean, using GTK+ , a module and
something else to make a visual scheduler monitor, how the tasks move
between "active" and "expired", where the task are in prio_array with
the bitmap fields...this module isn´t usefull, only in a didactic way.
I looked at hacking something into gtop etc. previously to use
/proc/kcore and pull out task information - I'd certainly like to see
a visual process monitor that could pull all of this stuff out and
display it for educational interest (page tables, vmas, other
resources). But then, it's probably been done - I didn't look to see
what else is out there.
Raul, Also take a look at relayfs. It's a fast way to record data in the
kernel and pass it back to a userland process. You'll have to patch the
kernel as it is said that the data needed is private to sched.c
Look into Documentation/filesystems/relayfs.txt
relayfs entered the kernel in 2.6.14.
