* IBM Powerpc Virtual Accelerator Switchboard (VAS)
VAS is a hardware mechanism that allows kernel subsystems and user processes
to directly submit compression and other requests to Nest accelerators (NX)
or other coprocessors functions.
Required properties:
- compatible : should be "ibm,vas".
- ibm,vas-id : A unique identifier for each instance of VAS in the system
- reg : Should contain 4 pairs of 64-bit fields specifying the Hypervisor
window context start and length, OS/User window context start and length,
"Paste address" start and length, "Paste window id" start bit and number
of bits)
Example:
vas@6019100000000 {
compatible = "ibm,vas", "ibm,power9-vas";
reg = <0x6019100000000 0x2000000 0x6019000000000 0x100000000 0x8000000000000 0x100000000 0x20 0x10>;
name = "vas";
ibm,vas-id = <0x1>;
};
