73 | * an IRQ notification will be raised.

74 | *
|
---|
75 | * VMMDev PDM interface will contain the guest notification method.
|
---|
76 | *
|
---|
77 | * There is a 32 bit event mask which will be read
|
---|
78 | * by guest on an interrupt. A non zero bit in the mask
|
---|
79 | * means that the specific event occured and requires
|
---|
80 | * processing on guest side.
|
---|
81 | *
|
---|
82 | * After reading the event mask guest must issue a
|
---|
83 | * generic request AcknowlegdeEvents.
|
---|
84 | *
|
---|
85 | * IRQ line is set to 1 (request) if there are unprocessed
|
---|
86 | * events, that is the event mask is not zero.
|
---|
87 | *
|
---|
88 | * After receiving an interrupt and checking event mask,
|
---|
89 | * the guest must process events using the event specific
|
---|
90 | * mechanism.
|
---|
91 | *
|
---|
92 | * That is if mouse capabilities were changed,
|
---|
93 | * guest will use VMMDev_GetMouseStatus generic request.
|
---|
94 | *
|
---|
95 | * Event mask is only a set of flags indicating that guest
|
---|
96 | * must proceed with a procedure.
|
---|
97 | *
|
---|
98 | * Unsupported events are therefore ignored.
|
---|
99 | * The guest additions must inform host which events they
|
---|
100 | * want to receive, to avoid unnecessary IRQ processing.
|
---|
101 | * By default no events are signalled to guest.
|
---|
102 | *
|
---|
103 | * This seems to be fast method. It requires
|
---|
104 | * only one context switch for an event processing.
