Subject: [PATCH 4/7] x86 power: define RAPL MSRs
Date: Wed, 14 Nov 2012 15:43:21 -0500	[thread overview]
Message-ID: <8e95037d0d9172c87a2b4ebeaff49c4e793ee5d2.1352925508.git.len.brown@intel.com> (raw)
In-Reply-To: <1352925804-6746-1-git-send-email-lenb@kernel.org>
In-Reply-To: <39300ffb9b6666714c60735cf854e1280e4e75f4.1352925508.git.len.brown@intel.com>

From: Len Brown <len.brown@intel.com>

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.
