Ah, I see, Ack. In that case, the UART is taken away from the root cell.
You can overcome this with the JAILHOUSE_MEM_ROOTSHARED flag. But be
aware that the inmate is then allowed to the UART device as well. So if
latencies that are introduced by hypervisor intervention due to
subpaging are not an issue for you, then subpaging is probably what you
want.
