  1. config VIRTIO
  2. tristate
  3. ---help---
  4. This option is selected by any driver which implements the virtio
  5. bus, such as CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_MMIO, CONFIG_LGUEST,
  6. CONFIG_RPMSG or CONFIG_S390_GUEST.
  7. menu "Virtio drivers"
  8. config VIRTIO_PCI
  9. tristate "PCI driver for virtio devices"
  10. depends on PCI
  11. select VIRTIO
  12. ---help---
  13. This drivers provides support for virtio based paravirtual device
  14. drivers over PCI. This requires that your VMM has appropriate PCI
  15. virtio backends. Most QEMU based VMMs should support these devices
  16. (like KVM or Xen).
  17. Currently, the ABI is not considered stable so there is no guarantee
  18. that this version of the driver will work with your VMM.
  19. If unsure, say M.
  20. config VIRTIO_BALLOON
  21. tristate "Virtio balloon driver"
  22. depends on VIRTIO
  23. ---help---
  24. This driver supports increasing and decreasing the amount
  25. of memory within a KVM guest.
  26. If unsure, say M.
  27. config VIRTIO_MMIO
  28. tristate "Platform bus driver for memory mapped virtio devices"
  29. depends on HAS_IOMEM
  30. select VIRTIO
  31. ---help---
  32. This drivers provides support for memory mapped virtio
  33. platform device driver.
  34. If unsure, say N.
  35. config VIRTIO_MMIO_CMDLINE_DEVICES
  36. bool "Memory mapped virtio devices parameter parsing"
  37. depends on VIRTIO_MMIO
  38. ---help---
  39. Allow virtio-mmio devices instantiation via the kernel command line
  40. or module parameters. Be aware that using incorrect parameters (base
  41. address in particular) can crash your system - you have been warned.
  42. See Documentation/kernel-parameters.txt for details.
  43. If unsure, say 'N'.
