Parameters

Context [in]

Prototype

SRIOV_RESET_FUNCTION SriovResetFunction;

NTSTATUS SriovResetFunction(
  _In_ PVOID  Context,
  _In_ USHORT VfIndex
)
{ ... }

typedef SRIOV_RESET_FUNCTION *PSRIOV_RESET_FUNCTION;

Remarks

This callback function is implemented by the physical function (PF) driver. It is invoked when the system wants to reset a specific virtual function.

The PF driver registers its implementation by setting the ResetVf member of the SRIOV_DEVICE_INTERFACE_STANDARD, configuring a WDF_QUERY_INTERFACE_CONFIG structure, and calling WdfDeviceAddQueryInterface.
