This is useful for testing, so that all event lists can be tested on a single system. Signed-off-by: Andi Kleen Signed-off-by: Sukadev Bhattiprolu v2: Fix double free in earlier version. Print actual CPUID being used with verbose option. --- tools/perf/util/pmu.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/tools/perf/util/pmu.c b/tools/perf/util/pmu.c index 790c64f..300975e 100644 --- a/tools/perf/util/pmu.c +++ b/tools/perf/util/pmu.c @@ -477,10 +477,16 @@ static int pmu_add_cpu_aliases(struct list_head *head) struct pmu_event *pe; char *cpuid; - cpuid = get_cpuid_str(); + cpuid = getenv("PERF_CPUID"); + if (cpuid) + cpuid = strdup(cpuid); + if (!cpuid) + cpuid = get_cpuid_str(); if (!cpuid) return 0; + pr_debug("Using CPUID %s\n", cpuid); + i = 0; while (1) { map = &pmu_events_map[i++]; -- 1.7.9.5
