Hi Julian

Below is my test.

tacy@tacy:~$ sudo perf record --call-graph dwarf -a
callchain: Unknown --call-graph option value: dwarf

 usage: perf record [<options>] [<command>]
    or: perf record [<options>] -- <command> [<options>]

        --call-graph <mode[,dump_size]>
                          setup and enables call-graph (stack chain/backtrace) recording: fp
