'mmap_pages' is 'unsigned int' not 'int' e.g. perf record -m2147483648 uname Permission error mapping pages. Consider increasing /proc/sys/kernel/perf_event_mlock_kb, or try again with a smaller value of -m/--mmap_pages. (current value: -2147483648) Fixed: perf record -m2147483648 uname Permission error mapping pages. Consider increasing /proc/sys/kernel/perf_event_mlock_kb, or try again with a smaller value of -m/--mmap_pages.
