From mboxrd@z Thu Jan 1 00:00:00 1970 From: Harry Butterworth Subject: [RFC][PATCH] allow dom0 to power off machine using ACPI on shutdown. Date: Thu, 06 Apr 2006 19:36:10 +0100 Message-ID: <1144348570.7725.9.camel@localhost.localdomain> Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="=-cJJrhoDmNgjhYq8eTdUW" Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xensource.com Errors-To: xen-devel-bounces@lists.xensource.com To: xen-devel@lists.xensource.com, niv@us.ibm.com List-Id: xen-devel@lists.xenproject.org --=-cJJrhoDmNgjhYq8eTdUW Content-Type: text/plain Content-Transfer-Encoding: 7bit This is an evil little patch which allows my dom0 to power off the machine on shutdown successfully and doesn't break my domU shutdown behaviour. The #if bits are ugly and are present because pm_power_off is declared above in the same #if context, maybe they are not necessary. I'm not sure about the solution for ia64. This powers down the machine without bothering to tell the hypervisor. I thought this kind of solution was better than trying to import a lot more ACPI cruft into Xen. Any thoughts? Harry.
