	int "Virtio PCI Polling Period (us)"
	depends on DRIVERS_VIRTIO_PCI
	default 0
	---help---
		if Polling Period <= 0, not support polling mode.
		if Polling Period > 0, support polling mode, and it represent
		polling period (us).

	---help---
		The buffer number in each virtqueue. (We have 2 virtqueues.)
		If this value equals to 0, use CONFIG_IOB_NBUFFERS / 4 for each.
		Normally we get just a little improvement for >8 buffers, and very little for >32.

	select SERIAL_CONSOLE
	---help---
		This enables using first virtio serial device as console.

config DRIVERS_VIRTIO_SERIAL_NAME
	string "Virtio serial driver name"
	default ""
	---help---
		Using this config to custom the virtio serial registered device name,
		using ";" to split the names.
		For example, if DRIVERS_VIRTIO_SERIAL_NAME = "ttyBT;ttyTEL" and pass
		three virtio-serial devices to the qemu, we will get three uart devices
		with names: "/dev/ttyBT", "/dev/ttyTEL", "/dev/ttyV2"
