Thread-topic: [Xen-devel] how can native driver response quickly for low FIFO device
Keir:
        For those devices like UART which has very few FIFOs and no DMA
support, how can scheduler (sedf?) help us to improve the response of
native device driver in driver domain? Otherwise the receive data may be
overwritten in driver domain and then makes the device unusable.
thx,eddie
