as mentioned in the question, I want to know if there is a possibility to read out a e.g. core register to get the current privilege state in user mode. (MSR PR-Bit).
Problem is that the MSR is not readable in user mode.
We'd like to add a mechanism to determine whether we need a system call to access specific memory regions (e.g. peripherals which are only accessible in supervisor mode) or not (Performance issues).
The solution should be usable for all e200zX cores.
Thank you in advance and best regards
