src/sys/arch/macppc/conf: GENERIC GENERIC_601 MAMBO
Remove legacy comment regarding the instability of awacs(4)
Enable awacs(4), skipping MAMBO config as it is for an emulator.
"that warning about the awacs driver making some
machines lock up can probably go. It's ancient and I've never seen it
actually happen, I have several oldish macs with different awacs
variants and it's enabled in all my configs. In fact it predates my
macppc interrupt cleanup ( I think I did that in 2005 or so ) and I
strongly suspect that fixed the problem.
( the ancient code didn't properly distinguish between edge and level
triggered interrupts on grand central / heathrow type hardware, IIRC it
always just checked the level register(s) which resulted in edge
triggered interrupts being missed or misdetected. Most of the mac-io
goop from that time uses edge triggered interrupts, which includes
If this actually happens to anyone I'd like to know about it"
