STARTIO_PERFORMANCE_PARAMETERS structure

The STARTIO_PERFORMANCE_PARAMETERS structure describes the performance parameters that are returned to the miniport driver by the StorPortGetStartIoPerfParams routine.

Syntax


typedef struct _STARTIO_PERFORMANCE_PARAMETERS {
  ULONG Version;
  ULONG Size;
  ULONG MessageNumber;
  ULONG ChannelNumber;
} STARTIO_PERFORMANCE_PARAMETERS, *PSTARTIO_PERFORMANCE_PARAMETERS;

Members

Version

The version number of the structure. This member is valid starting with Windows 8.

Size

MessageNumber

The offset in the device's MSI-X table for the optimal MSI-X message with which to interrupt. If the device does not support MSI-X messages, this member will be zero.
