* 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>;
|
|
};
