Hi all, I know that the perf_event_mlock_kb kernel parameter allows to limit the amount of counters sampling memory that can be mmap'ed by an unprivileged user.
Nevertheless, playing with the size I give to mmap some memory using the file descriptor returned by perf_event_open I am not able to linkk with the perf_event_mlock_kb parameter. Looking into kernel sources, it seems this parameter is used in kernel/events/core.c where the perf mmap operation is defined but I am not sure to understand the code there. So my question is what is the exact meaning of this parameter ? -- Manu -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
