Extend the feature in #11 to allow running perf on a remote machine via ssh, then stream the data to localhost

It would be nice if hotspot can help with the setup here, which might not be easy for novice users. Especially setting up debug symbols, which might only be available on the host's sysroot.

Presumably another thing that would be needed here would be to supply a symbol file other than the one named in perf.data, as the binary may reside at a different location locally.

@jonhoo not sure, but I think what you mention is implemented already. Have a look at the command line arguments, cf.:

  --kallsyms <path>        Path to kallsyms file which is used to resolve
                           kernel symbols.

                           information.

                           libraries.

                           and libraries.

Ah, yes, you're right. My bad for not digging a bit further.
