a question in Tutorial 09 - Privilege Level

[sunshine-lcc]

In the article in Tutorial 09 - Privilege Level, I realize how to switch to EL1, but I have a question that if I want to pass some parameter to EL1 function, like kernel_init(arg1, arg2), what can I do for this? Could you please help me?

You‘ll need to put these arguments in the CPU registers before the eret.

arg1 == x0, arg2 == x1, etc.
