Figure 2. Checking PCIe ID using Windows Device Manager.
To make debug over the network work, the target system needs to use a network card that WinDbg recognizes. The current list can be found at https://docs.microsoft.com/windows-hardware/drivers/debugger/supported-ethernet-nics-for-network-kernel-debugging-in-windows-10. Basically, all released Intel network cards are supported. The key here is released - models of not-yet released network cards are typically not supported by Windows. Thus, for targets not yet available in hardware you have to add a PCIe-attached network card that WinDbg knows about - like an i350 or i210.
On a Windows target running with a desktop available, you can check the PCIe ID using Windows Device Manager. Find the network device, open properties, and check the details for the hardware IDs. Figure 2 shows an example from Windows 10 on a QSP-x86 target.
You can also check for the PCI device ID of a network by using the Powershell command Get-PnpDevice. Look for the line "DeviceID" after the name of the network device appears (often, there are many virtual devices that also get listed by this command):
> Get-PnpDevice -Class "Net" | fl Caption : Intel(R) Ethernet Connection (3) I219-LM Description : Intel(R) Ethernet Connection (3) I219-LM InstallDate : Name : Intel(R) Ethernet Connection (3) I219-LM Status : Unknown Availability : ConfigManagerErrorCode : CM_PROB_PHANTOM ConfigManagerUserConfig : False CreationClassName : Win32_PnPEntity DeviceID : PCI\VEN_8086&DEV_15D7&SUBSYS_224517AA&REV_21\3&11583659&0&FE
From Simics side, you can check the PCIe ID using one of the
print-pci-config-regs and print-device-regs commands.
For example, network card on a QSP-x86 target
(PCIe ID 0x10CD is supported according to Microsoft):
