I'm on vacation now, I can't test it until I'm back, but that looks quite good overall (except maybe the MacOS-like constant naming for kXXXX :) However, does it work with more than 2 CPUs ? It seem to be rather dual CPU centric from my understanding of the ack mecanism... The TB sync code is also used on 4 CPU daystar machines and possibly some other chrp with more than 2 CPUs. Paul, any comment ? Ben. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
