Enum SystemStateTransitionRequest

pub enum SystemStateTransitionRequest {
    GetTerminationSystemState {
        responder: SystemStateTransitionGetTerminationSystemStateResponder,
    },
    GetMexecZbis {
        responder: SystemStateTransitionGetMexecZbisResponder,
    },
}

Provides protocol for fetching relevant information during a system state transition.

Variants

GetTerminationSystemState

Gets the termination state.

Fields

responder: SystemStateTransitionGetTerminationSystemStateResponder

GetMexecZbis

When the system termination state is MEXEC, in the course of shutting down, driver_manager will perform an mexec itself after suspending all drivers. This method allows driver manager to fetch the kernel and data ZBIs to be passed to zx_system_mexec().

This method only should only be invoked in the case MEXEC shutdown.

It is expected that the ZBI items specified by zx_system_mexec_payload_get() have not yet been appended to the provided data ZBI.

Returns

• ZX_ERR_BAD_STATE: The termination system state is not set to MEXEC.

Fields

responder: SystemStateTransitionGetMexecZbisResponder
