A user can use "--pm_notify_channel uart,allow_trigger_s5" to indicate the User VM is allowed to trigger system S5. "--pm_notify_channel uart" means a vuart channel will be created in the User VM to allow communication with the VM's life_mngr. The Service VM can then initiate S5 in the guest via its dm's monitor interface. The additional option, "allow_trigger_s5", will create a socket connection with the Service VM's life_mngr, allowing this VM to initiate system S5. v1 -> v2: - rename pm_notify_channel type to PWR_EVENT_NOTIFY_UART_TRIG_PLAT_S5 Tracked-On: #6034 Signed-off-by: Peter Fang <peter.fang@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
