2024-03-21perf beauty: Move uapi/linux/fs.h copy out of the directory used to build perfArnaldo Carvalho de Melo
It is mostly used only to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/include/ hierarchy, that is used just for scraping. The only case where it was being used to build was in tools/perf/trace/beauty/sync_file_range.c, because some older systems doesn't have the SYNC_FILE_RANGE_WRITE_AND_WAIT define, just use the system's linux/fs.h header instead, defining it if not available. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it, just <linux/fs.h> coming from either 'make install_headers' or from the system /usr/include/ directory.

2019-05-28perf trace: Beautify 'sync_file_range' argumentsArnaldo Carvalho de Melo
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>
