Hello reneeamossberg-r2388c‌

I have some questions about "Resource Domain Protection" in this document.

What is a minimum unit of CPU's to separate each domain partition?

In page 29, it have a partition between 4xCA53 and 2xCA72 CPUs.

I understand that it is reasonable to separate it because these CPUs are different core complex.

In page 30, it have a partition between 2xCA53 and 2xCA53+2xCA72.

Does it can separate 4xCA53 core to different partition like page 30 and 32?

You say "Each IP Block has Hardware-based resource protection ‘stitched’around it" in page 29.

Can it keep a "Hardware-based resource protection" following resource combination?

CPU1:CA53, CPU2:CA53 -> Linux

CPU3:CA53, CPU4:CA53, CPU0:CA72, ,CPU1:CA72 -> Android

I hope to know that different OS like Android and Linux can work with these CPU partitioning.

I look forward to hearing from you.

Best regards,

Ishii.
