962306a36Sopenharmony_ci	  VAS devices are found in POWER9-based and later systems, they
1062306a36Sopenharmony_ci	  provide access to accelerator coprocessors such as NX-GZIP and
1162306a36Sopenharmony_ci	  NX-842. This config allows the kernel to use NX-842 accelerators,
1262306a36Sopenharmony_ci	  and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV
1362306a36Sopenharmony_ci	  and POWER10 PowerVM platforms.
