HV_REGISTER_VALUE union

The HV_REGISTER_VALUE union describes virtual processor register values.

Syntax


typedef union _HV_REGISTER_VALUE {
  HV_UINT128                           Reg128;
  UINT64                               Reg64;
  UINT32                               Reg32;
  UINT16                               Reg16;
  UINT8                                Reg8;
  HV_X64_FP_REGISTER                   Fp;
  HV_X64_FP_CONTROL_STATUS_REGISTER    FpControlStatus;
  HV_X64_XMM_CONTROL_STATUS_REGISTER   XmmControlStatus;
  HV_X64_SEGMENT_REGISTER              Segment;
  HV_X64_TABLE_REGISTER                Table;
  HV_EXPLICIT_SUSPEND_REGISTER         ExplicitSuspend;
  HV_INTERCEPT_SUSPEND_REGISTER        InterceptSuspend;
  HV_X64_INTERRUPT_STATE_REGISTER      InterruptState;
  HV_X64_PENDING_INTERRUPTION_REGISTER PendingInterruption;
} HV_REGISTER_VALUE, *PHV_REGISTER_VALUE;

Members

Reg128: The register holds a full 128-bit value.
Reg64: The register holds a 64-bit value.
Reg32: The register holds a 32-bit value.
Reg16: The register holds a 16-bit value.
Reg8: The register holds an 8-bit value.
Fp: The register holds a floating-point value that is encoded with the HV_X64_FP_REGISTER union.
FpControlStatus: The register holds a floating-point control-status value that is encoded with the HV_X64_FP_CONTROL_STATUS_REGISTER union.
XmmControlStatus: The register holds a XMM floating-point control-status value that is encoded with the HV_X64_XMM_CONTROL_STATUS_REGISTER union.
Segment: The register holds a segment value that is encoded with the HV_X64_SEGMENT_REGISTER structure.
Table: The register holds a table value that is encoded with the HV_X64_TABLE_REGISTER structure.
ExplicitSuspend: The register holds an explicit-suspend value that is encoded with the HV_EXPLICIT_SUSPEND_REGISTER union.
InterceptSuspend: The register holds an intercept-suspend value that is encoded with the HV_INTERCEPT_SUSPEND_REGISTER union.
InterruptState: The register holds an interrupt-state value that is encoded with the HV_X64_INTERRUPT_STATE_REGISTER union.
PendingInterruption: The register holds a pending-interruption value that is encoded with the HV_X64_PENDING_INTERRUPTION_REGISTER union.

Remarks

Virtual processor register values are all 128 bits in size. Values that do not consume the full 128 bits are zero-extended to fill out the register's entire 128 bits.

The HV_REGISTER_VALUE union is passed to the HvGetVpRegisters and HvSetVpRegisters functions.
