      perf test: Remove 'core_id' check in topo test · 4c9d6c18
      Sukadev Bhattiprolu authored
      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
