Why are you trying to emulate a 2E system? OpenBSD/loongson has never been tested on a Fuloong 2E system and I wouldn't be surprised if it did not work at all on such a machine (and I've been unable to find one on the second hand market). You are likely yo get better results trying to emulate a 2F system. In any case, I'll conveniently blame qemu here, since there is no reason access to this register would fail. Miod
