Hi, Here is the 5th version of the patchset for probe-cache and initial SDT support which are going to be perf-cache finally.
The previous version is here; https://lkml.org/lkml/2016/4/26/179 This version fixes a build bug on "make build-test", removed accepted patches, and fold buildid-cache style change and backward compatibility patches. IOW, just a cleanup version :) TODOs are here, but I think it should involve kernel-side change to complete. - (perf record) Support SDT event recording directly - (perf record) Support @FILE/@BUILDID suffix to record specific SDTs. - (perf record) Try to unregister SDT events after record. - (ftrace) Support multiple SDTs on single event. Thank you, --- Hemant Kumar (1): perf/sdt: ELF support for SDT Masami Hiramatsu (14): perf probe: Use strbuf for making strings 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 | 278 ++++++++++--- 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 | 684 ++++++++++++++++++++++--------- tools/perf/util/probe-event.h | 9 tools/perf/util/probe-file.c | 492 ++++++++++++++++++++++ tools/perf/util/probe-file.h | 41 ++ tools/perf/util/probe-finder.c | 14 - tools/perf/util/symbol-elf.c | 252 +++++++++++ tools/perf/util/symbol.c | 15 - tools/perf/util/symbol.h | 22 + 16 files changed, 1689 insertions(+), 272 deletions(-) -- Masami Hiramatsu
