DXGKARG_GPUP_WRITE_VIRTUALIZED_MSIX structure (d3dkmddi.h)
The DXGKARG_GPUP_WRITE_VIRTUALIZED_MSIX structure is a parameter for the DxgkDdiWriteVirtualizedInterrupt function that writes to the MSI-X interrupt table during the process of live migration of a virtualized GPU device.
Syntax
typedef struct _DXGKARG_GPUP_WRITE_VIRTUALIZED_MSIX {
UINT vfIndex;
INT16 InterruptTableIndex;
DXGK_INTERRUPT_TABLE_ENTRY WriteValue;
} DXGKARG_GPUP_WRITE_VIRTUALIZED_MSIX;
Members
vfIndex
[in] Identifies the virtual function / vDEV being referenced. This index value localizes to the specific virtual device.
InterruptTableIndex
[in] Index of the MSI-X table entry to write to.
WriteValue
[in] A DXGK_INTERRUPT_TABLE_ENTRY structure that contains the data to write to the MSI-X table entry.
Remarks
For more information, see Live migration on GPU-P devices.
