From: Grigori Goronzy Date: Mon, 27 Apr 2009 07:23:40 +0000 (+0200) Subject: eeepc-laptop: support for super hybrid engine (SHE) X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=158ca1d75dd0d6223f3b1dd741d30777da62ab80;p=openwrt%2Fstaging%2Fblogic.git eeepc-laptop: support for super hybrid engine (SHE) The older eeepc-acpi driver allowed to control the SHE performance preset through a ACPI function for just this purpose. SHE underclocks and undervolts the FSB and undervolts the CPU (at preset 2, "powersave"), or slightly overclocks the CPU (at preset 0, "performance"). Preset 1 is the default setting with default clocks and voltage. The new eeepc-laptop driver doesn't support it anymore. The attached patch adds support for it to eeepc-laptop. It's very straight-forward and almost trivial.
