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?
