From dd5bcaf7b67568744cd003ac9e07e863780bda08 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 2 Jul 2014 14:50:46 +0200 Subject: [PATCH] mwait-idle: add CPU model 54 (Atom N2000 series) Add CPU ID for Atom N2600/N2800 processors. Datasheets indicate support for this, detailed information about potential quirks or limitations are missing, though. So we just reuse the definition for the previous ATOM series. Tests on N2800 systems showed that this addition is fine an can reduce power consumption by about 0.25 W (personally confirmed on Intel DN2800MT).
