Description

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.

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.
