Description

I am conducting tests on the RISCV multi-core processor AIA to enhance the efficiency of automatic testing. Independent of Linux, I am using OpenSBI as the fundamental environment to run test codes. Currently, I have managed to get OpenSBI to run on multiple cores. It seems that OpenSBI does not support handling interrupts of different privileges. I would like to ask why OpenSBI does not support running in other privileges? Will OpenSBI support handling interrupts of different privileges?

Research direction

No source file, test, or entry point is named. First identify OpenSBI's interrupt-handling path for multiple harts and privilege levels, then define the supported behavior and tests needed to demonstrate it.
