HV_MESSAGE_TYPE enumeration
The HV_MESSAGE_TYPE enumeration contains values that identify a type of message.
Syntax
typedef enum _HV_MESSAGE_TYPE { HvMessageTypeNone = 0x00000000, HvMessageTypeUnmappedGpa = 0x80000000, HvMessageTypeGpaIntercept = 0x80000001, HvMessageTimerExpired = 0x80000010, HvMessageTypeInvalidVpRegisterValue = 0x80000020, HvMessageTypeUnrecoverableException = 0x80000021, HvMessageTypeUnsupportedFeature = 0x80000022, HvMessageTypeEventLogBufferComplete = 0x80000040, HvMessageTypeX64IoPortIntercept = 0x80010000, HvMessageTypeX64MsrIntercept = 0x80010001, HvMessageTypeX64CpuidIntercept = 0x80010002, HvMessageTypeX64ExceptionIntercept = 0x80010003, HvMessageTypeX64ApicEoi = 0x80010004, HvMessageTypeX64LegacyFpError = 0x80010005 } HV_MESSAGE_TYPE, *PHV_MESSAGE_TYPE;
Constants
- HvMessageTypeNone
-
An array element (also known as a message slot) of a SIM page that corresponds to a single synthetic interrupt source (SINTx) is empty.
- HvMessageTypeUnmappedGpa
- HvMessageTypeGpaIntercept
- HvMessageTimerExpired
- HvMessageTypeInvalidVpRegisterValue
-
A virtual processor is suspended, and an intercept message of this type is sent to the virtual processor's parent partition.
- HvMessageTypeUnrecoverableException
- HvMessageTypeUnsupportedFeature
- HvMessageTypeEventLogBufferComplete
- HvMessageTypeX64IoPortIntercept
- HvMessageTypeX64MsrIntercept
- HvMessageTypeX64CpuidIntercept
- HvMessageTypeX64ExceptionIntercept
- HvMessageTypeX64ApicEoi
- HvMessageTypeX64LegacyFpError
Remarks
Any message type that has the high bit set is reserved for use by the hypervisor. Guest-initiated messages cannot be sent with a hypervisor message type.
The HV_MESSAGE_TYPE enumeration is used in the HV_MESSAGE_HEADER structure and passed to the HvPostMessage function.
