perf tests: Add daemon 'signal' command test
Add a test for the perf daemon 'signal' command. The test sends a signal to configured sessions and verifies the perf data files were generated accordingly. Committer testing: [root@five ~]# perf test daemon 76: daemon operations : Ok [root@five ~]# perf test -v daemon 76: daemon operations : --- start --- test child forked, pid 790017 test daemon list test daemon reconfig test daemon stop test daemon signal signal 12 sent to session 'test [790268]' signal 12 sent to session 'test [790268]' test child finished with 0 ---- end ---- daemon operations: Ok [root@five ~]# Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Budankov <abudankov@huawei.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: https://lore.kernel.org/r/20210208200908.1019149-23-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
