This structure describes the I/O operation which was in process when the SMI was generated.
For input instruction (IN, INS), this is data read before the SMI occurred. For output instructions (OUT, OUTS) this is data that was written before the SMI occurred. The width of the data is specified by IoWidth.
The I/O port that was being accessed when the SMI was triggered.
Defines type of I/O instruction.
Defines the size width (UINT8, UINT16, UINT32, UINT64) for IoData.
