The topology test case of 'perf test' seems to be broken on my x86 system - due to the comparison of a "core-id" with # of CPUs online. There are 8 online CPUs: $ cat /sys/devices/system/cpu/online 0-7 but core-ids are not sequential and some core-ids exceed the number of online CPUs. $ cat /sys/devices/system/cpu/cpu?/topology/core_id 0 1 9 10 0 1 9 10 Looks like we can safely remove the check. Output before: $ perf --version perf version 4.4.rc1.g34258a $ perf test -v topo 36: Test topology in session : --- start --- test child forked, pid 5906 templ file: /tmp/perf-test-vCwWG3 core_id number is too big.You may need to upgrade the perf tool. test child interrupted ---- end ---- Test topology in session: FAILED! and after: $ perf test -v topo 36: Test topology in session : --- start --- test child forked, pid 6532 templ file: /tmp/perf-test-y10wFJ CPU 0, core 0, socket 0 CPU 1, core 1, socket 0 CPU 2, core 9, socket 0 CPU 3, core 10, socket 0 CPU 4, core 0, socket 1 CPU 5, core 1, socket 1 CPU 6, core 9, socket 1 CPU 7, core 10, socket 1 test child finished with 0 ---- end ---- Test topology in session: Ok Signed-off-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Cc: Jan Stancek <jstancek@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Kan Liang <kan.liang@intel.com> Link: http://lkml.kernel.org/r/20151203233219.GA27696@us.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
