Functions
VirtIO endian conversion helpers
VirtIO prior to version 1.0 (legacy versions) normally send values to the host in the guest systems native byte order. This is going to change in version 1.0 which mandates little endian. We currently only support the legacy version of VirtIO (the new and shiny standard is still in a draft state and not implemented by the kernel). Once we support the new standard, we should negotiate the VirtIO version with the guest and automatically use the right type of byte swapping.
