Thanks for the insight into the current state. As I understand, some parts of AArch64 and AArch32 EL2 modes share a some functionality. For example, * VGIC - compatible * Exception Routing - different interface but same function * Pagetable format - implemented with LPAE * Generic Timer - different interface but same function Are these assumptions correct? I hope I didn't simplify it to much. And also: does it make sense to work with your code? Are you planing to commit the changes before May? Would someone mentor this project? Best regards, Merten
