From 5bcedee0f88fa6390d84f2641dc5b3e109cf6ea3 Mon Sep 17 00:00:00 2001 From: Xavi Drudis Ferran Date: Mon, 28 Feb 2011 03:25:07 +0000 Subject: Improving BKDG implementation of P-states, CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Add an untested step in BKDG 2.4.2.8. I don't have the hardware with Core Performance Boost and I think it's only available in revision E that does not even have a constant yet.
