STARTIO_PERFORMANCE_PARAMETERS structure (storport.h)
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.
