From c925401b6dc2229adbb15b2f3c9f0f2d9253a5d5 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Wed, 22 Aug 2007 18:44:20 -0700 Subject: [PATCH] [CPUFREQ] x86: use num_online_nodes to get physical cpus numbers for powernow_k8 [PATCH] x86: use num_online_nodes to get physical cpus numbers for powernow_k8 For opteron based system, don't assume all physical cpus have the same booted cpus even same cores. esp for downcore case.
