You should run ``dmesg |grep ttyS0`` to get port address from the output, and then

#. ``vuart=ttySn@irqN``: this tells the hypervisor which virtual serial device SOS
will use and its IRQ number. This is used to avoid conflict with SOS passthrough
devices' interrupt. If UART is set to ttyS1, and its native IRQ is 5, you'd better
set ``vuart=ttyS1@irq5`` (Use 'dmesg | grep tty' to get IRQ information).
Also set ``console=ttyS1`` in ``acrn.conf`` to match the SOS boot args.
Here is a more complete example of how to configure the EFI firmware to load the ACRN
hypervisor and set these parameters.

UP2 serial port setting
=======================
The serial port (ttyS1) in the 40-pin HAT connector is located at ``serial PCI BDF 0:18.1``.
You can check this from the ``lspci`` output from the initial Clearlinux installation.
Also you can use ``dmesg | grep tty`` to get its IRQ information for vuart setting; and update
SOS bootargs ``console=ttyS1`` in acrn.conf to match with vuart setting.
