Subject[PATCH] perf/tests: Fix test case 83 on s390
Date
Perf test case 83: perf stat CSV output linter might fail
on s390.
The reason for this is the output of the command

./perf stat -x, -A -a --no-merge true

which depends on a .config file setting. When CONFIG_SCHED_TOPOLOGY
is set, the output of above perf command is

CPU0,1.50,msec,cpu-clock,1502781,100.00,1.052,CPUs utilized

When CONFIG_SCHED_TOPOLOGY is *NOT* set the output of above perf
command is

0.95,msec,cpu-clock,949800,100.00,1.060,CPUs utilized

Fix the test case to accept both output formats.

Output before:
# perf test 83
83: perf stat CSV output linter : FAILED!
#

Output after:
# ./perf test 83
83: perf stat CSV output linter : Ok
#

Fixes: ec906102e5b7 ("perf test: Fix "perf stat CSV output linter" test on s390")
