Members

Header: An HV_X64_INTERCEPT_MESSAGE_HEADER structure that describes the header for the I/O access intercept message.
PortNumber: The number of the I/O port that is being accessed.
AccessInfo: An HV_X64_IO_PORT_ACCESS_INFO union that indicates the size of the access, whether the intercepted instruction was a string operation, and whether a "rep" prefix was specified.
InstructionByteCount: An 8-bit value that specifies the number of instruction bytes that are provided in the InstructionBytes member.
Reserved: Reserved. Do not use.
Rax: The value for the virtual processor's 64-bit RAX general-purpose register.
InstructionBytes: An array of bytes that make up the instruction stream for the I/O access intercept message. The number of valid bytes is specified by the InstructionByteCount member.
DsSegment: An HV_X64_SEGMENT_REGISTER structure that describes the selector, base, limit, and flags for the current data segment (DS).
EsSegment: An HV_X64_SEGMENT_REGISTER structure that describes the selector, base, limit, and flags for the current extended segment (ES).
Rcx: The value for the virtual processor's 64-bit RCX general-purpose register.
Rsi: The value for the virtual processor's 64-bit RSI general-purpose register.
Rdi: The value for the virtual processor's 64-bit RDI general-purpose register.
