I am running perf stat to count hardware counters but am confused about stall cycle support. On running the command perf stat ./progname, I am told that stalled-cycles- frontend and stalled-cycles-backend are not counted, but when on running perf stat -v ./progname, I am told that stall cycles are not supported by the kernel.
