Hello all,
I finally managed to run perf with LBR unwinding for user-space call stacks,
see also: https://lkml.org/lkml/2015/4/14/232
It really works much better and faster than the DWARF based unwinder. Is
anyone working on adding support for that to libunwind? It would be really
nice to have, I think - especially for profilers that use libunwind.
Thanks
