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. Here is an example: ---- $ perf test sdt -v 47: Test SDT event probing : --- start --- test child forked, pid 20732 Found 72 SDTs in /home/mhiramat/ksrc/linux/tools/perf/perf Writing cache: %sdt_perf:test_target=test_target Cache committed: 0 symbol:test_target file:(null) line:0 offset:0 return:0 lazy:(null) test child finished with 0 ---- end ---- Test SDT event probing: Ok ---- Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Ananth N Mavinakayanahalli <ananth@linux.vnet.ibm.com> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Hemant Kumar <hemant@linux.vnet.ibm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/146831796546.17065.1502584370844087537.stgit@devbox Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
