└─>SCMI VirtIO transport Version 1 compliance
In linux kernel since version 5.2 (release Date: 2019-07-07)  
This enforces strict compliance with VirtIO Version 1 specification.

If you want the ARM SCMI VirtIO transport layer to refuse to work
with Legacy VirtIO backends and instead support only VirtIO Version 1
devices (or above), answer Y.

If you want instead to support also old Legacy VirtIO backends (like
the ones implemented by kvmtool) and let the core Kernel VirtIO layer
take care of the needed conversions, say N.
