Currently perf requires the -m / --mmap_pages option to be a power of 2. To be more user friendly perf should automatically round this up to the next power of 2. Currently: $ perf record -m 3 -a -- sleep 1 --mmap_pages/-m value must be a power of two.sleep: Terminated With patch: $ perf record -m 3 -a -- sleep 1 rounding mmap pages size to 16384 (4 pages) ... v2: Add bytes units to rounding message per Ingo's request. Other suggestions (e.g., prefixing INFO) should be addressed by wrapping pr_info to catch all instances.
