Thank Bill for updating this.

I want to use this thread to follow up on the topic 'secure interrupt' given in the 1st tech forum. That is a prologue of the scheduler and interrupt designs. And I do see there are some use cases that I did not focus on, so I want to collect more user scenarios first, and then try to enhance the drafting design (will be published after I updated it base on your inputs).

About the secure interrupt usage: - A secure interrupt would be introduced by a secure service call in general; is there any scenarios that there would be an interval secure interrupt since secure service want to do something? For example, a secure timer triggers to let secure service has the chance to do things in the background (not for an ongoing secure call from NSPE) after a period of time?

And the question about the system Alan mentioned, just want to confirm if it is a pure thread mode scheduling system? How does the system handle interrupts?

Thanks.
