-```markdown
-perf list      show supported hw/sw events
-
-perf stat
-  -p <pid> .. show stats for running process
-  -I <ms> ... show stats periodically over interval <ms>
-  -e <ev> ... filter for events
-
-perf top
-  -p <pid> .. show stats for running process
-  -F <hz> ... sampling frequency
-  -K ........ hide kernel threads
-
-perf record
-  -p <pid> ............... record stats for running process
-  -F <hz> ................ sampling frequency
-  --call-graph <method> .. [fp, dwarf, lbr] method how to caputre backtrace
-                           fp   : use frame-pointer, need to compile with
-                                  -fno-omit-frame-pointer
-                           dwarf: use .cfi debug information
-                           lbr  : use hardware last branch record facility
-  -g ..................... short-hand for --call-graph fp
-  -e <ev> ................ filter for events
-
-perf report
-  -n .................... annotate symbols with nr of samples
-  --stdio ............... report to stdio, if not presen tui mode
-  -g graph,0.5,caller ... show caller based call chains with value >0.5

-```markdown
-perf record -g -e cpu-cycles,page-faults -p <pid>
-perf script --per-event-dump
-# fold & generate as above
