Thread-Index: Ach0m4cSiApNdLdFScC3DSTHVH8H7w== From: "Wappler Marcel" To: X-OriginalArrivalTime: 10 Apr 2008 08:14:41.0600 (UTC) FILETIME=[ED627C00:01C89AE2] Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi all, I am looking for ways to let an ARM9 based embedded device running Linux go to a "suspend to RAM" like mode. In my opinion this could enable a HIFI equipement like "power-off" and "power-on" feeling with quick response (less than 2 seconds) and much less power consumption in the standby mode than during normal operation. - Is there public available documentation about APM like features on ARM architectures? - Is there a mainstream Linux platform (best if also ARM9 based) which has achieved this already? - I am also interested in experiences with applications running on such platforms, trigger like systems which inform the apps and so on...
