CONFIG_VIRTIO_PCI: PCI driver for virtio devices

General informations

The Linux kernel configuration item CONFIG_VIRTIO_PCI has multiple definitions:

PCI driver for virtio devices found in drivers/virtio/Kconfig

The configuration item CONFIG_VIRTIO_PCI:

• prompt: PCI driver for virtio devices
• type: tristate
• depends on: CONFIG_PCI
• defined in drivers/virtio/Kconfig
• found in Linux kernels: 3.9–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD
• modules built: virtio_pci

Help text

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.

PCI driver for virtio devices (EXPERIMENTAL) found in drivers/virtio/Kconfig

The configuration item CONFIG_VIRTIO_PCI:

• prompt: PCI driver for virtio devices (EXPERIMENTAL)
• type: tristate
• depends on: CONFIG_PCI && CONFIG_EXPERIMENTAL
• defined in drivers/virtio/Kconfig
• found in Linux kernels: 2.6.25–2.6.39, 3.0–3.8
• modules built: virtio_pci

Help text

This drivers 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).

Currently, the ABI is not considered stable so there is no guarantee that this version of the driver will work with your VMM.

If unsure, say M.
