HV_SYNIC_SCONTROL union
The HV_SYNIC_SCONTROL union describes encoding for a SynIC control register.
Syntax
typedef union _HV_SYNIC_SCONTROL { UINT64 AsUINT64; struct { UINT64 Enable :1; UINT64 ReservedP :63; }; } HV_SYNIC_SCONTROL, *PHV_SYNIC_SCONTROL;
Members
- AsUINT64
-
A member in the union that can hold one 64-bit value that describes encoding for a SynIC control register.
- Enable
-
A 64-bit value that indicates whether message queuing and event flag notifications are posted to the virtual processor's SynIC. When clear, message queuing and event flag notifications cannot be directed to the virtual processor. Setting this member is equivalent to setting the first bit (bit 0) of the 64-bit AsUINT64 member (0x0000000000000001).
- ReservedP
-
This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting each of the remaining 63 bits (0xFFFFFFFFFFFFFFFE) of the 64-bit AsUINT64 member to zero.
Remarks
For more information about how SynIC control registers are encoded, see SCONTROL Register.
