/* Whenever host wants to inform guest about something
* an IRQ notification will be raised.
*
* VMMDev PDM interface will contain the guest notification method.
*
* There is a 32 bit event mask which will be read
* by guest on an interrupt. A non zero bit in the mask
* means that the specific event occurred and requires
* processing on guest side.
*
* After reading the event mask guest must issue a
* generic request AcknowlegdeEvents.
*
* IRQ line is set to 1 (request) if there are unprocessed
* events, that is the event mask is not zero.
*
* After receiving an interrupt and checking event mask,
* the guest must process events using the event specific
* mechanism.
*
* That is if mouse capabilities were changed,
* guest will use VMMDev_GetMouseStatus generic request.
*
* Event mask is only a set of flags indicating that guest
* must proceed with a procedure.
*
* Unsupported events are therefore ignored.
* The guest additions must inform host which events they
* want to receive, to avoid unnecessary IRQ processing.
* By default no events are signalled to guest.
*
* This seems to be fast method. It requires
* only one context switch for an event processing.
