In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
A virtual stateless decoder device for uAPI development purposes.

A userspace implementation can use visl to run a decoding loop even
when no hardware is available or when the kernel uAPI for the codec
has not been upstreamed yet. This can reveal bugs at an early stage.

When in doubt, say N.
