[Libunwind-devel] unwind user process from kernel?

[Collin McCurdy]

I am interested in using libunwind to examine, from the kernel, the stack of an interrupted user process (due to hardware performance counter overflow, for example).

Would the right way to go about this be to use the remote interface via unw_create_addr_space() and appropriate accessor functions?  Or is there an easier way?  Has this been done already?

Thanks for any advice,

Collin
