Hi,
Another fun fact I forgot to mention: if I profile only this thread, and
then run opreport with cpu filtering, it only shows results on the right
cpu. So the wrong accounting only happens when I do system wide
profiling. But not just with this thread and function, other functions
appear a

Hi,
I'm using OProfile to check some suspicious behaviour of dpdk-pktgen,
and I can see something which troubles me. Either the scheduler lies
about core affinity or Oprofile accounts some samples wrongly.
This userspace app runs in threads, which are assigned explicitly to one

That is IO scheduler. Can we use the same for threads/processes?

Your kernel source is incomplete. You can fetch a vanilla kernel
tarball from http://kernel.org.

the web shows that there should sched_fair.c but
I can not find that in the source directory (the
kernel source has been installed).
Basically, I want to
