Commit39d62336f5("s390/pai: add support for cryptography counters") added support for Processor Activity Instrumentation Facility (PAI) counters. These counters values are added as raw data with the perf sample during 'perf record'. Now add support to display these counters in the 'perf report' command. The counter number, its assigned name and value is now printed in addition to the hexadecimal output. Output before: # perf report -D 6 514766399626050 0x7b058 [0x48]: PERF_RECORD_SAMPLE(IP, 0x1): 303977/303977: 0 period: 1 addr: 0 ... thread: paitest:303977 ...... dso: <not found> 0x7b0a0@/root/perf.data.paicrypto [0x48]: event: 9 . . ... raw event: size 72 bytes . 0000: 00 00 00 09 00 01 00 48 00 00 00 00 00 00 00 00 .......H........ . 0010: 00 04 a3 69 00 04 a3 69 00 01 d4 2d 76 de a0 bb ...i...i...-v... . 0020: 00 00 00 00 00 01 5c 53 00 00 00 06 00 00 00 00 ......\S........ . 0030: 00 00 00 00 00 00 00 01 00 00 00 0c 00 07 00 00 ................ . 0040: 00 00 00 53 96 af 00 00 ...S....
