I find the following related patches about this feature by David Daney <david.daney@...ium.com> and Archer Yan <ayan@...ecomp.com> in Sep 2019. [1/2] Support mips unwinding and dwarf-regs https://lore.kernel.org/patchwork/patch/1126521/ [2/2] Support extracting off-line stack traces from user-space with perf https://lore.kernel.org/patchwork/patch/1126520/ Is this a work in progress? Could you please give me some feedback? Thank you for your help. Thanks, Tiezhu
