perf record: Add --all-user/--all-kernel options
Allow user to easily switch all events to user or kernel space with simple --all-user or --all-kernel options. This will be handy within perf mem/c2c wrappers to switch easily monitoring modes. Committer note: Testing it: # perf record --all-kernel --all-user -a sleep 2 Error: option `all-user' cannot be used with all-kernel Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] --all-user Configure all used events to run in user space. --all-kernel Configure all used events to run in kernel space. # perf record --all-user --all-kernel -a sleep 2 Error: option `all-kernel' cannot be used with all-user Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] --all-kernel Configure all used events to run in kernel space. --all-user Configure all used events to run in user space. # perf record --all-user -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.416 MB perf.data (162 samples) ] # perf report | grep '\[k\]' # perf record --all-kernel -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.423 MB perf.data (296 samples) ] # perf report | grep '\[\.\]' # Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1455525293-8671-2-git-send-email-jolsa@kernel.org [ Made those options to be mutually exclusive ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
