0007 This enables support for IBM Virtual Accelerator Switchboard (VAS).
0008
0009 VAS devices are found in POWER9-based and later systems, they
0010 provide access to accelerator coprocessors such as NX-GZIP and
0011 NX-842. This config allows the kernel to use NX-842 accelerators,
0012 and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV
0013 and POWER10 PowerVM platforms.
