- # 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.
