This enables support for IBM Virtual Accelerator Switchboard (VAS).
|
||
|
|
|
||
|
|
VAS allows accelerators in co-processors like NX-GZIP and NX-842
|
||
|
|
to be accessible to kernel subsystems and user processes.
|
||
|
|
|
||
|
|
VAS adapters are found in POWER9 based systems.

If unsure, say N.
