List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: xen-devel@lists.xensource.com, Gerd Hoffmann 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.
