| 6 | # VirtIO is a virtualization standard for network and disk device drivers |
| 7 | # where just the guest's device driver "knows" it is running in a virtual |
| 8 | # environment, and cooperates with the hypervisor. This enables guests to |
| 9 | # get high performance network and disk operations, and gives most of the |
| 10 | # performance benefits of paravirtualization. In the U-Boot case, the guest |
| 11 | # is U-Boot itself, while the virtual environment are normally QEMU targets |
| 12 | # like ARM, RISC-V and x86. |
| 13 | # |
| 14 | # See http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf for |
| 15 | # the VirtIO specification v1.0. |
