From 93a4fa622eb061f75f87f0cf9609ab4e69c67d01 Mon Sep 17 00:00:00 2001 From: Qing Zhang Date: Sat, 6 Aug 2022 16:10:04 +0800 Subject: LoongArch: Add STACKTRACE support 1. Use common arch_stack_walk() infrastructure to avoid duplicated code and avoid taking care of the stack storage and filtering. 2. Add sched_ra (means sched return address) and sched_cfa (means sched call frame address) to thread_info, and store them in switch_to(). 3. Add __get_wchan() implementation. Now we can print the process stack and wait channel by cat /proc/*/stack and /proc/*/wchan.
