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
tacy@tacy:~$ uname -a
