Use existing beautifiers for the first arg, fd, assigned using the heuristic that looks for syscall arg names and associates SCA_FD with 'fd' named argumes, and wire up the recently introduced sync_file_range flags table generator. Now it should be possible to just use: perf trace -e sync_file_range As root and see all sync_file_range syscalls with its args beautified. Doing a syscall strace like session looking for this syscall, then run postgresql's initdb command: # perf trace -e sync_file_range <SNIP> initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(7</var/lib/pgsql/data/base/1/2682>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(7</var/lib/pgsql/data/base/1/2682>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(5</var/lib/pgsql/data/global>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(4</var/lib/pgsql/data>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 initdb/1332 sync_file_range(4</var/lib/pgsql/data>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0 ^C # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Amir Goldstein <amir73il@gmail.com> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-8tqy34xhpg8gwnaiv74xy93w@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
