You are right! Thank you very much for your help! I have successfully executed the jailhouse on my device.
But I have another question. I noticed that Jailhouse shuts down the CPU virtually instead of physically. What's the purpose of this? I tried to power off the CPU without going through EL2, but the result was that it could not be powered back on. Of course I changed some parameters state parameters in the structure, if not ignored ones. Is it feasible? Thank you again for your time~ 在2022年8月16日星期二 UTC+8 21:09:43<[email protected]> 写道： > You are using Android with Trusty in inmate cell? jailhouse not support > trusty SMC handler.
