| 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". |
