4 depends on (PPC_POWERNV || PPC_PSERIES) && PPC_64K_PAGES
7 This enables support for IBM Virtual Accelerator Switchboard (VAS).
9 VAS devices are found in POWER9-based and later systems, they
10 provide access to accelerator coprocessors such as NX-GZIP and
11 NX-842. This config allows the kernel to use NX-842 accelerators,
12 and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV
13 and POWER10 PowerVM platforms.
