# VirtIO is a virtualization standard for network and disk device drivers
# where just the guest's device driver "knows" it is running in a virtual
# environment, and cooperates with the hypervisor. This enables guests to
# get high performance network and disk operations, and gives most of the
# performance benefits of paravirtualization. In the U-Boot case, the guest
# is U-Boot itself, while the virtual environment are normally QEMU targets
# like ARM, RISC-V and x86.
#
# See http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf for
# the VirtIO specification v1.0.

config VIRTIO
	bool
	help
	  This option is selected by any driver which implements the virtio
	  transport, such as CONFIG_VIRTIO_MMIO or CONFIG_VIRTIO_PCI.

config VIRTIO_MMIO
	bool "Platform bus driver for memory mapped virtio devices"
	select VIRTIO
	help
	  This driver provides support for memory mapped virtio
	  platform device driver.

config VIRTIO_PCI
	bool "PCI driver for virtio devices"
	depends on DM_PCI
	select VIRTIO
	help
	  This driver provides support for virtio based paravirtual device
	  drivers over PCI.

config VIRTIO_SANDBOX
	bool "Sandbox driver for virtio devices"
	depends on SANDBOX
	select VIRTIO
	help
	  This driver provides support for Sandbox implementation of virtio
	  transport driver which is used for testing purpose only.

config VIRTIO_NET
	bool "virtio net driver"
	depends on VIRTIO
	help
	  This is the virtual net driver for virtio. It can be used with
	  QEMU based targets.

config VIRTIO_BLK
	bool "virtio block driver"
	depends on VIRTIO
	help
	  This is the virtual block driver for virtio. It can be used with
	  QEMU based targets.
