perf test session topology: Fix test on s390
On s390 this test case fails because the socket identifiction numbers assigned to the CPU are higher than the CPU identification numbers. F/ix this by adding the platform architecture into the perf data header flag information. This helps identifiing the test platform and handles s390 specifics in process_cpu_topology(). Before: [root@p23lp27 perf]# perf test -vvvvv -F 39 39: Session topology : --- start --- templ file: /tmp/perf-test-iUv755 socket_id number is too big.You may need to upgrade the perf tool. ---- end ---- Session topology: Skip [root@p23lp27 perf]# After: [root@p23lp27 perf]# perf test -vvvvv -F 39 39: Session topology : --- start --- templ file: /tmp/perf-test-8X8VTs CPU 0, core 0, socket 6 CPU 1, core 1, socket 3 ---- end ---- Session topology: Ok [root@p23lp27 perf]# Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: Hendrik Brueckner <brueckner@linux.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Fixes: c84974ed9fb6 ("perf test: Add entry to test cpu topology") Link: http://lkml.kernel.org/r/20180611073153.15592-2-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
