Hi, The Terminal DXE driver appends the chosen terminal type as a child node to the currently present ConIn/ConOut devices. It appends only one of the 9 terminal types as the child node. But the ConInDev/ConOutDev variables have list of device paths with all possible terminal types, of which only one of the terminal types can be used at a time.
On the other hand the TestPointCheckLib checks for actual presence of devices that are listed in ConInDev/ConOutDev. So in this case, since only one of the terminal type is actually present at any time, this test fails for the rest of the terminal types. 1) Is this by design that Terminal DXE driver installs only one terminal type at any given time, out of the 9 available? 2) Why is the entire list of all terminal devices, instead of one terminal type which is presently chosen, added to ConInDev and ConOutDev variables? The UEFI spec says "The device path of all possible console input devices.", so in this context, does 'possible devices' include non existent devices too? 3) If this is the case, then do we need to modify TestPointCheckLib to check for presence of terminal type child node and thereby ignoring the terminal part and check only if parent device exist of not? The current TestPointCheckLib code checks for all terminal types present in ConInDev and ConOutDev and throws error because only one of such device is actually present. The error I'm seeing is ==== TestPointCheckConsoleVariable - Enter ConIn: VenHw(D3987D4B-971A-435F-8CAF-4967EB627241)/Uart(115200,8,N,1)/VenPcAnsi(),/UsbHID(0xFFFF,0xFFFF,0x1,0x1) ConInDev: UsbHID(0xFFFF,0xFFFF,0x1,0x1),/VenHw(D3987D4B-971A-435F-8CAF-4967EB627241)/Uart(115200,8,N,1)/VenPcAnsi(),/VenHw(D3987D4B-971A-435F-8CAF-4967EB627241)/Uart(115200,8,N,1)/VenVt100(),/VenHw(D3987D4B-971A-435F-8CAF-4967EB627241)/Uart(115200,8,N,1)/DevicePath not found!
