typedef struct {
UINT64 GpaAddress; // GPA address of the memory access
UINT8 Direction; // Read or write
UINT8 AccessSize; // 1, 2, 4, or 8 bytes
union {
UINT64 Value; // Input value (for write), output value (for read)
UINT64 GpaAddress2; // GPA address of the second instruction operand
};
} MMIO_ACCESS_INFO;
