For some limited cases, it can significantly reduce the sample overhead. Please read patch 6's commit message for more information. changes since v1: - drop patch 'perf, core: Add all PMUs to pmu_idr' - add comments for case that multiple counters overflow simultaneously changes since v2: - rename perf_sched_cb_{enable,disable} to perf_sched_cb_user_{inc,dec} - use flag to indicate auto reload mechanism - move codes that setup PEBS sample data to separate function - output the PEBS records in batch - enable this for All (PEBS capable) hardware - more description for the multiplex changes since v3: - ignore conflicting PEBS record -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
