[PATCH perf/core v11 21/23] perf probe: Support a special SDT probe format

Support a special SDT probe format which can omit the '%' prefix only if the SDT group name starts with "sdt_". So, for example both of "%sdt_libc:setjump" and "sdt_libc:setjump" are acceptable for perf probe --add. Suggested-by: Brendan Gregg Signed-off-by: Masami

[PATCH perf/core v11 19/23] perf probe: Search SDT/cached event from all probe caches

Search SDT/cached event from all probe caches if user doesn't pass any binary. With this, we don't have to specify target binary for SDT and named cached events (which start with %). E.g. without this, a target binary must be passed with -x. # perf probe -x /usr/lib64/libc-2.20.so -a

[PATCH perf/core v11 18/23] perf probe: Allow wildcard for cached events

Allo glob wildcard for reusing cached/SDT events. E.g. # perf probe -x /usr/lib64/libc-2.20.so -a %sdt_libc:\* This example adds probes for all SDT in libc. Note that the SDTs must have been scanned by perf buildid-cache. Signed-off-by: Masami Hiramatsu --- Changes in

[PATCH perf/core v11 23/23] perf-test: Add a test case for SDT event

Add a basic test case for SDT event support. This test scans an SDT event in perftools and check whether the SDT event is correctly stored into the buildid cache. Signed-off-by: Masami Hiramatsu --- tools/perf/tests/Build |1 tools/perf/tests/builtin-test.c |

[PATCH perf/core v11 20/23] perf probe: Support @BUILDID or @FILE suffix for SDT events

Support @BUILDID or @FILE suffix for SDT events. This allows perf to add probes on SDTs/pre-cached events on given FILE or the file which has given BUILDID (also, this complements BUILDID.) For example, both gcc and libstdc++ has same SDTs as below. If you would like to add a probe on
