* - :kbd:`--acpidev_pt <HID>`
- This option is to enable ACPI device passthrough support. The ``HID`` is a
mandatory parameter for this option which is the Hardware ID of the ACPI
device.
Example::
--acpidev_pt MSFT0101
To pass through a TPM (which HID is MSFT0101) ACPI device to a User VM.
* - :kbd:`--mmiodev_pt <MMIO_Region>`
- This option is to enable MMIO device passthrough support. The ``MMIO_Region``
is a mandatory parameter for this option which is the MMIO resource of the
MMIO device. The ``MMIO_Region`` needs to be the base address followed by
the length of the region, both separated by a comma.
Example::
--mmiodev_pt 0xFED40000,0x00005000
To pass through a MMIO device to a User VM. The MMIO device has a MMIO region.
The base address of this region is 0xFED40000 and the size of the region
is 0x00005000.
* - :kbd:`--vtpm2 <sock_path>`
