Ok, so we either don't enable some interrupts or we enable the wrong
ones for whatever reason.
Which interrupts does snapper use on your machine?
Looks like 30 for state changes, 1 for output and 2 for input. Irq 1
and 2
look strange because all other interrupts are in a region above 20.
OF shows the same.
That looks right, my iBook uses the same:
interrupts 0000001e 00000001 00000001 00000000 00000002 00000000
Please check if the
interrupt the cardbus bridge uses matches the interrupt register and
the OF node. It wouldn't be the first time that one of them is lying.
Pcidump shows the same interrupt (53) as in dmesg. The cardbus
memory and
i/o regions look a bit strange, but maybe that's ok when no card is
inserted?
CardBus memory region 0:
base register: 0xfffff000
limit register: 0x00000000
CardBus memory region 1:
base register: 0xfffff000
limit register: 0x00000000
CardBus I/O region 0:
base register: 0xfffffffc
limit register: 0x00000000
CardBus I/O region 1:
base register: 0xfffffffc
limit register: 0x00000000
Interrupt line: 0x35
Interrupt pin: 0x01 (pin A)
Looks the same here except for the different interrupt - the Pismo
uses 0x3a.
You may want to sprinkle some printf()s over arch/powerpc/pic/
pic_openpic.c and friends to verify that the right interrupts are
being enabled, aren't blocked elsewhere, are the right type ( as in
edge vs. level triggered ) etc.
The interrupt map in OF doesn't seem right to me:

Looks almost the same here.
Looking at the OF tree I should use the "name" or "compatible"
property for
"audio-gpio" and "reg" for "AAPL,address". But the contents of "reg"
is not
the final address and has probably to be added to some base
address of
obio?
It /should/ be relative to obio/gpio although sometimes it's relative
to obio. The whole thing is a mess thanks to Apple being inconsistent
even withing a single OF variant - my iBook has some gpios with
addresses relative to obio and others - on the same parent node -
relative to obio/gpio and the code tries to guess which one it is. So
please leave existing functionality intact no matter how insane it
looks, it's there for a reason.
Ok!
I have just committed a modified deq.c, which matches the PowerBook5,6
codec, while leaving the existing functionality intact. :)
Thanks :)
On my iBook the gpio node has an address of 0x50 which is relative to
obio. Some of its child nodes have addresses < 0x50 which we treat as
relative to gpio, others have offsets > 0x50 which we treat as
relative to obio. This works on my iBook G4, it may or may not work
on
other machines with different variants of this insanity.
Ok. I think I have already seen that in the gpio code of obio.c.
I wonder why the hell they couldn't just pick one addressing scheme
and stick with it or at lease be consistent within the same OF tree.
That's great! I hope I didn't break anything now. Can you also test
with my
patched ofwboot?
I will. Do you have a beige G3 to confirm?
No, unfortunately not. Besides the new PowerBook I have only a
PowerMac G4
(400) and a Mac Mini.
All UniNorth machines, as far as NetBSD is concerned there's little
difference between them.
have fun
