When some of CPUs are offline: # cat /sys/devices/system/cpu/online 0,6-31 perf test will fail on #3 testcase: 3: detect open syscall event on all cpus: --- start --- perf_evsel__read_on_cpu: expected to intercept 111 calls on cpu 0, got 681 perf_evsel__read_on_cpu: expected to intercept 112 calls on cpu 1, got 117 perf_evsel__read_on_cpu: expected to intercept 113 calls on cpu 2, got 118 perf_evsel__read_on_cpu: expected to intercept 114 calls on cpu 3, got 119 perf_evsel__read_on_cpu: expected to intercept 115 calls on cpu 4, got 120 perf_evsel__read_on_cpu: expected to intercept 116 calls on cpu 5, got 121 perf_evsel__read_on_cpu: expected to intercept 117 calls on cpu 6, got 122 perf_evsel__read_on_cpu: expected to intercept 118 calls on cpu 7, got 123 perf_evsel__read_on_cpu: expected to intercept 119 calls on cpu 8, got 124 perf_evsel__read_on_cpu: expected to intercept 120 calls on cpu 9, got 125 perf_evsel__read_on_cpu: expected to intercept 121 calls on cpu 10, got 126 .... This patch try to use 'cpus->map[cpu]' when setting cpu affinity, and will check the return code of sched_setaffinity() LKML-Reference: <20110120114707.GA11781@hpt.nay.redhat.com> Signed-off-by: Han Pingtian <phan@redhat.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
