+ This enables support for IBM Virtual Accelerator Switchboard (VAS).
+
+ VAS devices are found in POWER9-based and later systems, they
+ provide access to accelerator coprocessors such as NX-GZIP and
+ NX-842. This config allows the kernel to use NX-842 accelerators,
+ and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV
+ and POWER10 PowerVM platforms.
+
+ If unsure, say "N".
