H A Dpai_crypto.json5a6c184a Fri Oct 21 03:25:57 CDT 2022 Thomas Richter <tmricht@linux.ibm.com> perf list: Fix PMU name pai_crypto in perf list on s390

Commit e0b23af82d6f454c ("perf list: Add PMU pai_crypto event
description for IBM z16") introduced the "Processor Activity
Instrumentation" for cryptographic counters for z16. The PMU device
driver exports the counters via sysfs files listed in directory
/sys/devices/pai_crypto.

To specify an event from that PMU, use 'perf stat -e pai_crypto/XXX/'.

However the JSON file mentioned in above commit exports the counter
decriptions in file pmu-events/arch/s390/cf_z16/pai.json. Rename this
file to pmu-events/arch/s390/cf_z16/pai_crypto.json to make the naming
consistent.

Now 'perf list' shows the counter names under pai_crypto section:

pai_crypto:

CRYPTO_ALL
[CRYPTO ALL. Unit: pai_crypto]
...

Output before was

pai:
CRYPTO_ALL
[CRYPTO ALL. Unit: pai_crypto]
...
