FWIW, I had to port the SUSE's in-kernel DWARF unwinder which we drag for a decade or so. It seems to be working correctly on the top of the rewritten 4.9 stack unwinding. It needs a lot of polishing, though. And it does not go beyond a single stack (e.g. from IRQ to process ctx) yet (it never did). https://git.kernel.org/cgit/linux/kernel/git/jirislaby/linux.git/commit/?h=devel&id=b190fa08c9248846e9cf23959f0484215d3ad0e4 Having the working DWARF unwinder, I am moving to DWARF generation for asm in your tool now. thanks, -- js suse labs
