[Bug 1836862] Re: [18.04 FEAT] Enhanced CPU-MF hardware counters - s390tools part

[Frank Heimes]

I've up a test LPAR for bionic with counters and sampling facilities enabled (in the activation profile) and did a verification of the cpumf tools included in the s390-tools package version 2.3.0-0ubuntu3.5 - it's more a regression testing, since I only have access to z13 machine.
Anyway, on the z13 machine I was able to successfully use and run lscpumf, chcpumf and perf  - I executed some samples and they all looked good, no issues, error or regressions found.
Hence adjusting bionic tag ...

  Fix Committed
Status in s390-tools source package in Disco:

Bug description:
  [Impact]

   * Add more counters to support more hw, i.e. z14 counters.

  [Test Case]

   * Test that lscpumf / chcpumf still work
   * Check that additional counters are now available on compatible hw

  [Regression Potential]

   * It is a cherrypick from upstream which is already shipped in eoan.
  All existing counters remain (renamed source file), and csvn-6
  counters are added. Otherwise the functionality of using the counters
  remain the same, thus this is almost dataset change only to match new
  hardware.

  [Other Info]
   
   * Original bug report.

  Enhance the CPU-MF hardware counters for improved HW support .

  Addl s390-tools 2.10.0 commit required in addition to the kernel part.
