config VIRTIO
tristate
---help---
This option is selected by any driver which implements the virtio
bus, such as CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_MMIO, CONFIG_LGUEST,
CONFIG_RPMSG or CONFIG_S390_GUEST.
menu "Virtio drivers"
config VIRTIO_PCI
tristate "PCI driver for virtio devices"
depends on PCI
select VIRTIO
---help---
This driver provides support for virtio based paravirtual device
drivers over PCI. This requires that your VMM has appropriate PCI
virtio backends. Most QEMU based VMMs should support these devices
(like KVM or Xen).
If unsure, say M.
config VIRTIO_PCI_LEGACY
bool "Support for legacy virtio draft 0.9.X and older devices"
default y
depends on VIRTIO_PCI
---help---
Virtio PCI Card 0.9.X Draft (circa 2014) and older device support.
This option enables building a transitional driver, supporting
both devices conforming to Virtio 1 specification, and legacy devices.
If disabled, you get a slightly smaller, non-transitional driver,
with no legacy compatibility.
So look out into your driveway. Do you have a flying car? If
so, you can happily disable this option and virtio will not
break. Otherwise, leave it set. Unless you're testing what
life will be like in The Future.
If unsure, say Y.
config VIRTIO_BALLOON
tristate "Virtio balloon driver"
depends on VIRTIO
select MEMORY_BALLOON
---help---
This driver supports increasing and decreasing the amount
of memory within a KVM guest.
If unsure, say M.
config VIRTIO_INPUT
tristate "Virtio input driver"
depends on VIRTIO
depends on INPUT
---help---
This driver supports virtio input devices such as
keyboards, mice and tablets.
If unsure, say M.
config VIRTIO_MMIO
tristate "Platform bus driver for memory mapped virtio devices"
depends on HAS_IOMEM
select VIRTIO
---help---
This drivers provides support for memory mapped virtio
platform device driver.
If unsure, say N.
config VIRTIO_MMIO_CMDLINE_DEVICES
bool "Memory mapped virtio devices parameter parsing"
depends on VIRTIO_MMIO
---help---
Allow virtio-mmio devices instantiation via the kernel command line
or module parameters. Be aware that using incorrect parameters (base
address in particular) can crash your system - you have been warned.
See Documentation/kernel-parameters.txt for details.
If unsure, say 'N'.
