Yes, I'm talking about Dhrystone benchmark. We are carrying kernel-only version in lib/dhry_*.c, it is in -next now.
commit cfbd4cc940275240e97f8b922c8f18a44fe15c07 Author: Geert Uytterhoeven <geert+renesas@glider.be> Date: Thu Dec 8 15:31:28 2022 +0100
lib: add Dhrystone benchmark test
I'd like userspace-too version, at the same place :-).
Best regards, Pavel
