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