src/sys/arch/macppc/conf: GENERIC GENERIC_601 MAMBO
Log Message:
Remove legacy comment regarding the instability of awacs(4)
Enable awacs(4), skipping MAMBO config as it is for an emulator.
>From <macallan>
"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
awacs )
If this actually happens to anyone I'd like to know about it"
