From: Len Brown Date: Thu, 1 Nov 2012 00:47:40 +0000 (-0400) Subject: x86 power: define RAPL MSRs X-Git-Tag: next-20121102~77^2~1 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8e95037d0d9172c87a2b4ebeaff49c4e793ee5d2;p=karo-tx-linux.git x86 power: define RAPL MSRs The Run Time Average Power Limiting interface is currently model specific, present on Sandy Bridge and Ivy Bridge processors. These #defines correspond to documentation in the latest "Intel® 64 and IA-32 Architectures Software Developer Manual", plus some typos in that document corrected.
