Subject: perf tests: Skip 'perf stat metrics (shadow stat) test' for hybrid
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a37f3b885610f89c3f2285756eb3f386288c3d41;p=linux.git

perf tests: Skip 'perf stat metrics (shadow stat) test' for hybrid

Currently we don't support shadow stat for hybrid.

  root@ssp-pwrt-002:~# ./perf stat -e cycles,instructions -a -- sleep 1

   Performance counter stats for 'system wide':

      12,883,109,591      cpu_core/cycles/
       6,405,163,221      cpu_atom/cycles/
         555,553,778      cpu_core/instructions/
         841,158,734      cpu_atom/instructions/

         1.002644773 seconds time elapsed

Now there is no shadow stat 'insn per cycle' reported. We will support
it later and now just skip the 'perf stat metrics (shadow stat) test'.
