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. menu "VirtIO Drivers" 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 PCI select VIRTIO help This driver provides support for virtio based paravirtual device drivers over PCI. config VIRTIO_PCI_LEGACY bool "PCI driver for legacy virtio devices" depends on PCI select VIRTIO default VIRTIO_PCI help This driver provides support for legacy 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_SANDBOX_EMUL bool "Sandbox MMIO emulator for virtio devices" depends on SANDBOX select VIRTIO help This driver provides an MMIO interface to an emulation of a block device. It is used for testing purpose only. config VIRTIO_NET bool "virtio net driver" depends on VIRTIO && NETDEVICES 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 select BLK help This is the virtual block driver for virtio. It can be used with QEMU based targets. config VIRTIO_RNG bool "virtio rng driver" depends on DM_RNG depends on VIRTIO default y help This is the virtual random number generator driver. It can be used with QEMU based targets. config VIRTIO_FS bool "virtio filesystem driver" depends on VIRTIO && FS default y help Provides support for virtio-fs which provides access to host files within the guest OS. This needs a user-space helper (virtiofsd) when running QEMU - see https://virtio-fs.gitlab.io/ for details. A specification for the protocol is available at https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html config VIRTIO_SCSI bool "SCSI driver for virtio devices" depends on SCSI select VIRTIO default y help This driver provides support for virtio-based paravirtual SCSI. It allows access to storage devices using the A specification for the protocol is available at https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html endmenu |
