Windows 如何开启SRIOV，开启后VF会在设备管理器显示否？

本人尝试了如下操作

eStatus = WdmQueryForInterface(i_pdevinfo->PhysicalDeviceObject, &GUID_BUS_INTERFACE_STANDARD, (PINTERFACE)&pciBus, sizeof(BUS_INTERFACE_STANDARD));

if (eStatus != STATUS_SUCCESS)

{

VLOG_ERR("pciBus faild status=0x%x \r\n", eStatus);

goto skip_vf_en;

}

bytesRead = pciBus.GetBusData(pciBus.Context, PCI_WHICHSPACE_CONFIG, &pciHeader,

0, PCI_COMMON_HDR_LENGTH);

if (bytesRead != (ULONG)PCI_COMMON_HDR_LENGTH) {

goto skip_vf_en;

}

capabilityOffset = FindExtendCapability(&pciBus, &pciHeader, PCI_EXPRESS_SINGLE_ROOT_IO_VIRTUALIZATION_CAP_ID);

VASTAI_PCI_INFO(ppcieinfo, 0, "%s() ===capabilityOffset=%d\n", __func__, capabilityOffset);

if (capabilityOffset == 0) {

goto skip_vf_en;

}

bytesRead = pciBus.GetBusData(pciBus.Context, PCI_WHICHSPACE_CONFIG, &pcieSriovCapabilities, capabilityOffset, sizeof(pcieSriovCapabilities));

if (bytesRead != sizeof(pcieSriovCapabilities)) {

LOG_ERR("GetBusData ->pcieSriovCapabilities 0x%x != 0x%x \r\n", bytesRead, sizeof(pcieSriovCapabilities));

goto skip_vf_en;

}

eStatus = WdmQueryForInterface(i_pdevinfo->PhysicalDeviceObject, &GUID_PCI_VIRTUALIZATION_INTERFACE, (PINTERFACE)&pciVirInterface, sizeof(PCI_VIRTUALIZATION_INTERFACE));

if (eStatus != STATUS_SUCCESS)

{

VLOG_ERR("pciVirInterface faild status=0x%x \r\n", eStatus);

goto skip_vf_en;

}

VASTAI_PCI_INFO(ppcieinfo, 0, "%s() pciVirInterface=0x%llx \n", __func__, pciVirInterface);

if(pciVirInterface.EnableVirtualization != NULL)

{

eStatus = pciVirInterface.EnableVirtualization(pciVirInterface.Context, pcieSriovCapabilities.NumVFs, TRUE, TRUE, TRUE);

if (!NT_SUCCESS(eStatus))

{

VLOG_ERR("EnableVirtualization faild status=0x%x \r\n", eStatus);

goto skip_vf_en;

}
