[ Upstream commit 5a6c184a72a375072cffe788d93ad6052c48f16b ]
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]
...
