--- Begin Message ---Package: linux-tools-3.10 Version: 3.10-4 Severity: normal Dear Maintainer, The "perf record" command "-g <method>" option doesn't support a "dwarf" method in Debian. As the "dwarf" allows operating on programs which were compiled without a frame pointer (the default on amd64), "dwarf" is very handy. Here's what it does in debian: $ perf record -g dwarf echo hi callchain: Unknown -g option value: dwarf usage: perf record [<options>] [<command>] ... etc ... It looks like perf only supports "dwarf" if it was compiled with libunwind, so I suppose Debian didn't have that installed when compiling it. Could you make sure perf is compiled with libunwind, so the very handy "dwarf" -g method works?
