Questions about RME-DA and on-chip devices

Hi all,

I read the latest verion (vB.a) of the manual Arm Realm Management Extension (RME) System Architecture (https://developer.arm.com/documentation/den0129/latest/). Now I have several questions on page 17, Figure A1.1: RME System Architecture.

Q1: It seems that RME-DA supports PCIe devices but does not support on-chip devices. Is it correct? If yes, will RME-DA support it in the future?

Q2: Another problem is: How to define the on-chip device or peripheral? For example, if I use a Hikey960/JunoR2 board, will the SoC Mali GPU be an on-chip device, or a peripheral, or neither?

Can someone help me?
