Re: zero filling pages

P.S. The actual page zero routine is xnu/osfmk/ppc/movc.s and my impression is that there is a lot of Voodoo in it.

As I am unwinding my goof-stack, I retract this as well, since I understand(*) the MMU, sync / isync Voodoo now.

Well on the actual topic, things have become pretty quiet here. So I suspect a big political movement towards having an option to turn zero filling off (maybe as an option in the mach header of an executable) is unlikely.

Oh well, don't say I didn't try at least :)

Ciao
Nat!

(*) Well almost, is the MMU turned off because that page is not mapped into the kernel TLBs ?
