I understand that the existing behavior is suboptimal for power, but on the other hand, code that goes out of its way to *clear* the L1 flag doesn't just pop up out of nowhere. Somebody clearly wrote that! If it just meant "we didn't verify L1 at first", then maybe it's fine to enable it unconditionally and see what happens, but if it meant "we tried L1 on some old chip XXXX and it caused problems", then it would be nice to know what those problems were. Or maybe that is hard to figure out, given there's no public git history tracking the original code, and we just need to try it out. Anyway, I'm giving it a try here, but I just wanted to ask :) Thanks, Brian
