Add sysprof - preformance profiler for Linux - to the development tools. Patches for mips/arm are from openembedded code. sysprof-cli <outfile> get required events/stack frames. Next outfile can be loaded/displayed on PC using sysprof. Tool using: - PERF events - /proc/kallsyms for kernel symbols You should compile kernel with profiling enabled, debug information, symbol table information.
