perf test: Fix perf test case 84 on s390
Perf test case 84 'perf pipe recording and injection test' sometime fails on s390, especially on z/VM virtual machines. This is caused by a very short run time of workload # perf test -w noploop which runs for 1 second. Occasionally this is not long enough and the perf report has no samples for symbol noploop. Fix this and enlarge the runtime for the perf work load to 3 seconds. This ensures the symbol noploop is always present. Since only s390 is affected, make this loop architecture dependend. Output before: Inject -b build-ids test [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.195 MB - ] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.277 MB - ] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.195 MB - ] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.160 MB /tmp/perf.data.ELzRdq (4031 samples) ] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.195 MB - ] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.195 MB - ] Inject -b build-ids test [Success] Inject --buildid-all build-ids test [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.195 MB - ] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.014 MB - ] Inject --buildid-all build-ids test [Failed - cannot find noploop function in pipe #2] Output after: Successful execution for over 10 times in a loop.
