The cpumf_helper.in is called to parse counter definition
files stored in /usr/share/s390-tools/cpumf directory and
returns perl references to be examined by other perl tools
such as lsctrdef.
cpumf_helper.in expects several keywords in the counter
definition files, one is 'shortdesc' which contains
a short description of the purpose of the counter.
However this short description not is stored in the hash
field shortdesc keyed by counter number 'ctr' because the
wrong key is used.
Output before:
{
'64' => {
'desc' => 'Total number of the PRNG functions issued by the CPU',
'name' => 'PRNG_FUNCTIONS',
'set' => 8
},
'65' => {
'desc' => 'Total number of CPU cycles when the DEA/AES coprocessor is busy performing PRNG functions issued by the CPU',
'name' => 'PRNG_CYCLES',
'set' => 8
},
....
'ctr' => { <-------- WRONG
'shortdesc' => 'AES Blocked Cycles'
}
}
Output with this patch:
{
'64' => {
'desc' => 'Total number of the PRNG functions issued by the CPU',
'name' => 'PRNG_FUNCTIONS',
'set' => 8,
'shortdesc' => 'PRNG Functions'
},
'65' => {
'desc' => 'Total number of CPU cycles when the DEA/AES coprocessor is busy performing PRNG functions issued by the CPU',
'name' => 'PRNG_CYCLES',
'set' => 8,
'shortdesc' => 'PRNG Cycles'
},
...
}

Update the cpumf helper program to read the split counter set
definition files. Changes to higher-level program like lscpumf
are not necessary.

With z14, the counters in the problem-state are reduced resulting
in an increased first version number of the CPUM CF. To adapt to
this change, split the counter sets according to their counter
first and second version number. The second version number controls
the crypto-activity and extended counter set. Treat the crypto-activity
counter set as generic, as the extended counter set is already handled
based on hardware models.
