config stage-2 translation

Hello, everybody!
I encountered a problem in the process of opening el2 stage2 address mapping on arm. I wanted to configure the one-to-one mapping from IPA to PA, but the error was reported as follows.

[ 37.921623] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:

I want to know how to configure TS0Z and PS in vtcr_el2 and what impact they have.
It would be better if the mailer could explain it in detail or give a sample code.
Thank you all
