Hi, Here is the 6th version of the patchset for probe-cache and initial SDT support.
The previous version is here; https://lkml.org/lkml/2016/4/27/828 This version fixes some bugs according to reviews and bugs found by tests. Changes in v6: - [01/14] Replace local __is_regular_file with is_regular_file in util.c (Thank you Namhyung!) - [01/14] Fix dso__build_id_is_kmod() to check symlink in buildid cache correctly. - [03/14] Remove unneeded O_APPEND from open(). (Thanks Namhyung!) - [03/14] Fix to check the return value of probe_cache_entry__new and strdup.(ditto) - [04/14] Remove fallback lookup routine by using function name as cached event name, because it should be done by following patch which supports %cached-event. Thank you, --- Hemant Kumar (1): perf/sdt: ELF support for SDT Masami Hiramatsu (13): perf-buildid-cache: Use path/to/bin/buildid/elf instead of path/to/bin/buildid perf-buildid-cache: Use lsdir for looking up buildid caches perf probe: Add --cache option to cache the probe definitions perf probe: Use cache entry if possible perf probe: Show all cached probes perf probe: Remove caches when --cache is given perf probe: Add group name support perf buildid-cache: Scan and import user SDT events to probe cache perf probe: Accept %sdt and %cached event name perf-list: Show SDT and pre-cached events perf-list: Skip SDTs placed in invalid binaries perf probe: Allow wildcard for cached events perf probe: Support @BUILDID or @FILE suffix for SDT events tools/perf/Documentation/perf-probe.txt | 24 + tools/perf/builtin-list.c | 4 tools/perf/builtin-probe.c | 30 ++ tools/perf/util/build-id.c | 289 ++++++++++++++---- tools/perf/util/build-id.h | 6 tools/perf/util/dso.h | 5 tools/perf/util/parse-events.c | 83 +++++ tools/perf/util/parse-events.h | 2 tools/perf/util/probe-event.c | 431 ++++++++++++++++++++++++--- tools/perf/util/probe-event.h | 7 tools/perf/util/probe-file.c | 500 +++++++++++++++++++++++++++++++ tools/perf/util/probe-file.h | 41 +++ tools/perf/util/symbol-elf.c | 252 ++++++++++++++++ tools/perf/util/symbol.c | 15 + tools/perf/util/symbol.h | 22 + 15 files changed, 1600 insertions(+), 111 deletions(-) -- Masami Hiramatsu
