From: Gerd Hoffmann <kraxel@redhat.com> To: qemu-devel@nongnu.org Cc: xen-devel@lists.xensource.com, Gerd Hoffmann <kraxel@redhat.com> Subject: [Qemu-devel] [PATCH v3 5/6] suspend: make serial ports wakeup the guest. Date: Wed, 8 Feb 2012 12:00:18 +0100 [thread overview] Message-ID: <1328698819-31269-6-git-send-email-kraxel@redhat.com> (raw) In-Reply-To: <1328698819-31269-1-git-send-email-kraxel@redhat.com> Add a 'wakeup' property to the serial port. It is off by default. When enabled any incoming character on the serial line will wake up the guest. Useful for guests which have a serial console configured.
