| # 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. |
