The powerpc-hcalls.py script currently prints hypercall statistics in a fixed sort order based on the number of hcall occurrences, making it difficult to analyze hcalls from different execution characteristics. Add support for runtime-configurable sorting so users can order hypercall statistics by count, minimum latency, maximum latency, or average latency using a --sort option. Parse arguments through sys.argv to support perf script argument passing semantics. Example: perf record -a -e powerpc* sleep 10 perf script -s ./powerpc-hcalls.py -i ./perf.data -- --sort=max SORT KEY = max hcall count min(ns) max(ns) avg(ns) H_SEND_LOGICAL_LAN 47 7380 40148 8739 H_VIO_SIGNAL 706 880 17454 1911 H_RANDOM 1 15176 15176 15176 H_PUT_TCE_INDIRECT 4 3032 10444 4956 H_ADD_LOGICAL_LAN_BUFFER 363 1250 8716 1534 H_SEND_CRQ 8 2086 6846 3044 H_PUT_TCE 9 1284 4932 2646 H_STUFF_TCE 13 1620 3962 2358 This makes it easier to identify frequently occurring or high-latency hypercalls depending on the analysis being performed.
