Hmmm, Am I doing something wrong here?!?!?
This is the output I get from an IBM z17 machine:
root@b83lp65:~# dpkg -l | grep s390-tools
ii s390-tools 2.37.0-0ubuntu2.1

The extended counter set is missing completely. There are only 28
counters listed.
When I download the s390-tools repo and build it on the same machine, I get
this:
# cpumf/lscpumf -C| grep -E '^10:'
.... now some counters from the extended counter set

There are 105 counters listed. This is ok. 28 counters are not
enough....
So is this a build issue?
