From 41013cd63c068e2f271fabc92702ee67d800f0cb Mon Sep 17 00:00:00 2001 From: Andy Polyakov Date: Sat, 2 Jun 2018 14:03:27 +0200 Subject: PPC assembly pack: correct POWER9 results. As it turns out originally published results were skewed by "turbo" mode. VM apparently remains oblivious to dynamic frequency scaling, and reports that processor operates at "base" frequency at all times. While actual frequency gets increased under load.
