DXGKDDI_RESTOREMUTABLEMIGRATIONDATA callback function (d3dkmddi.h)
The receiving-side OS calls DxgkDdiRestoreMutableMigrationData to restore mutable data that was saved by the sending-side driver in a previous call to DxgkDdiSaveMutableMigrationData.
Syntax
DXGKDDI_RESTOREMUTABLEMIGRATIONDATA DxgkddiRestoremutablemigrationdata;
NTSTATUS DxgkddiRestoremutablemigrationdata(
IN_CONST_HANDLE hAdapter,
IN_CONST_PDXGKARG_GPUP_RESTORE_MUTABLE_MIGRATION_DATA pArgs
)
{...}
Parameters
hAdapter
[in] A handle to a context block associated with a display adapter. The display miniport driver previously provided this handle to Dxgkrnl in the MiniportDeviceContext output parameter of the DXGKDDI_ADD_DEVICE function.
pArgs
[in] Pointer to a DXGKARG_GPUP_RESTORE_MUTABLE_MIGRATION_DATA structure that contains information needed to restore the mutable data.
Return value
DxgkDdiRestoreImmutableMigrationData returns STATUS_SUCCESS if the call is successful. Otherwise, it returns an appropriate NTSTATUS code.
Remarks
This DDI should only ever be called for VFs that are currently paused.
