lscpumf script is available and does not crash, manpage is available too, anything further is not scope of this bug. Thus I'm closing it.

  install/cpumf: work with the CPU-measurement facilities (s390-tools)

  Fix Released
Status in s390-tools package in Debian:
  Fix Released

Bug description:
  == Comment: #0 - Hendrik Brueckner - 2016-03-16 12:55:28 ==
  This is a request to package a set of utilities to display information
  about the CPU-measurement counter and sampling facilities.  Both facilities
  provide hardware support for counters (cycles, instructions, etc.) and
  sampling.

  The lscpumf command displays information about the installed facilities
  and provide an overview of authorized and available hardware counters.
  The counter list informs users about authorized hardware counters and
  its number and symbolic name, for example, to be specified for perf tool.

  The chcpumf command changes sampling buffer charactistics for the kernel
  support for the hardware sampler.

  Apart from the user command, there is a helper program to parse data
  files.
