Multithreading in gem5 aarch64 FS using taskset

[itamarbon]

I am trying to explore multithreading on a gem5 simulator running through LKMC. I want to run different processes on different CPUs, and am trying to bind the tasks to each CPU using taskset. I get -/bin/sh: taskset: not found when I try to run the command. What can I do to enable this utility in for aarch64 FS? Thanks, Itamar

Ah, now I understood the problem taskset is not built in by default, can you rebuild the image with:

./build-buildroot \
  --arch aarch64 \
  --config 'BR2_PACKAGE_UTIL_LINUX=y' \
  --config 'BR2_PACKAGE_UTIL_LINUX_SCHEDUTILS=y' \
;

This is mentioned at: https://cirosantilli.com/linux-kernel-module-cheat/#gdb-step-debug-multicore-userland but might not be clear from other sections.
