From 9792db6174d9927700ed288e6d74b9391bf785d1 Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Thu, 29 Jul 2010 17:13:42 -0700 Subject: x86, cpu: Package Level Thermal Control, Power Limit Notification definitions Add package level thermal and power limit feature support. The two MSRs and features are new starting with Intel's Sandy Bridge processor. Please check Intel 64 and IA-32 Architectures SDMV Vol 3A 14.5.6 Power Limit Notification and 14.6 Package Level Thermal Management. This patch also fixes a bug which defines reverse THERM_INT_LOW_ENABLE bit and THERM_INT_HIGH_ENABLE bit.
