efi_loader: implement event queue

2019-06-10T21:06:19+00:00

Up to now we have only been using a flag queued for events. But this does
not satisfy the requirements of the UEFI spec. Events must be notified in
the sequence of decreasing TPL level and within a TPL level in the sequence
of signaling.

Implement a queue for signaled events.

efi_loader: event signaling in ExitBootServices

2019-06-10T21:06:19+00:00

ExitBootServices() has to stop timer related activity before calling the
events of the EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event group. But our
current implementation was stopping all other events.

All events have to observe the task priority level.

efi_loader: SignalEvent for event in signaled state

2019-06-10T21:06:19+00:00

If an event is already in the signaled state, SignalEvent should not queue
the notification function but simply return EFI_SUCCESS.

efi_loader: RegisterProtocolNotify event signaling

2019-06-10T21:06:19+00:00

In a following patch efi_signal_event() will only queue an event if it is
not signaled.

Set the is_signaled status to false before signaling the event.

Pull request for UEFI sub-system for v2019.07-rc4-2

Support for managing the non-volatile attribute of UEFI variables
is added though we do not have a backend for persistence yet.

Error messages for changes of UEFI variables are provided.

UEFI boottime service implementations are corrected.
