I think so too.

I think that PCI Interrupt Link Devices were originally intended to map
PIRQs down into PIC IRQs with standard PCI semantics -- obsoleting the
bogus chip-set specific PIRQ router "standard". But the BIOS can ask us
to do just about anything, and I'm finding that some system designers
and BIOS writers have become much more creative in their use;-)
Marco,
Please file a bug per below and attach the output of acpidmp and lspci
-v with full dmesg so I can decode what the BIOS is really asking us to
do.
Perhaps you can also add the dmesg and /proc/interrupts from the version
of 2.4 that worked. I'm puzzled at what 2.6-specific change provoked
this failure.
Thanks,
-Len
How to file a bug against ACPI:
http://bugzilla.kernel.org/
Category: Power Management
Component: ACPI
Please attach the output from acpidmp, available in /usr/sbin/, or in
here
http://www.intel.com/technology/iapc/acpi/downloads/pmtools-20010730.tar
.gz
Please attach /proc/interrupts, lspci -v and the dmesg output showing
the failure, if possible.

Actually, it _does_ seem to make a difference. The irq probe doesn't
report failure any more:

so now we have happily apparently probed the irq, but the problem is that
it continues to scream afterwards. So we're still unhappy, but something
did actually change.
I wonder why ACPI matters. It must be changing the polarity or trigger of
the irq somehow - but your earlier dmesg output seems to imply that it
only changes ELCR for irq9, so it must be somewhere else. Len, ideas?
Also, Marco, it might actually be a VIA IDE driver bug, that leaves the
interrupt on during setup somewhere (and the bug just doesn't matter when
the IRQ is edge-triggered). So it would be interesting to know what
happens if you disable the VIA-specific IDE support...
(Btw, thanks for being so good at testing, despite the lack of major
progress).

There was nothing before this?
The probe failed _before_ the first warning?
If so, that means that the probing didn't try IRQ 15 for some other reason
than it already being requested for a device. That other reason is most
likely that IRQ 15 was "screaming" when the IRQ probe already started,
which would have made the irq probing turn it off.
So something in the ACPI code made IRQ15 active, or caused there to be a
pending interrupt. I'd guess that ACPI incorrectly turns the legacy IDE
interrupts to be PCI interrupts (level-triggered, active low) instead of
legacy interrupts (edge-triggered, active high).
But I also have to admit that the IDE irq probing code looks a bit
fragile. We could be more careful about making sure that the IDE
controller has its interrupt turned off before we start probing. So a
patch like this might be in order - it should just make autoprobing a bit
more robust.
Does this one make a difference?
Len - does ACPI ever change the polarity of an interrupt? Just turning the
irq level-triggered shouldn't matter that much, but if some part of ACPI
switches polarities around (and gets the wrong one) that would be deadly
and would cause screaming interrupts when no event is pending.

Was ACPI enabled on the version of 2.4 that worked? If yes, I'd like to
see the 2.4 dmesg and /proc/interrupts.
[BTW Marco, If you collect a lot of info related to this failure, please
be encouraged to attach it to a bug report --
http://bugzilla.kernel.org/ Category: Power Management, Component: ACPI
-- the output from acpidmp would be helpful]
> noapic
This will have no effect -- we're already in PIC mode.
I don't know anything about the ide layer probing interrupts, but this
one is an interesting case at the low level.
> ACPI: PCI Interrupt Link [LNKH] (IRQs 3 4 5 6 7 9 10 11 12)
Here the BIOS gives us a lot of possible choices for where to send LNKH,
but the list does not include 15.
> ACPI: PCI Interrupt Link [LNKH] enabled at IRQ 15
> -> edge<6>PCI: Using ACPI for IRQ routing
Here we program LNKH to 15, which means the BIOS told us it was already
active on 15 -- there's no way we would have selected 15 based on the
list of possibles above.
Then we set the interrupt to level triggered -- as we do with all PCI
interrupts. This may be a bad assumption -- though we do exactly the
same thing in 2.4... In any case, Marco, perhaps you can try this quick
hack to skip that setting for 15 and perhaps that will add a clue.

That doesn't explain the lack of autodetection, and the early irq15
registration.
That would explain why no interrupts make it at all, but why do we not
even probe for irq15 here?

It's a long standing bug in how we handle VIA on board devices in ACPI.
It was a big problem on x86-64 too until I cheated and used only
PIC mode when there is a VIA southbridge.
Basically VIA has very specific rules on what interrupts can be assigned
to the onboard devices and they use an unusual ACPI construct for that
See http://bugme.osdl.org/show_bug.cgi?id=1530 for some more details.
(the same problem applies to 2.6 afaik)
Here's also some older description from VIA about the issues I saved:
>>
1) The _SRS method can only cope with IRQs <= 15 if SB is before VT8233.
After VT8235, _SRS method need not report IRQ for internal devices due to they are
+hardwired to fixed IRQ in APIC mode.
[AK: that is one problem with the ACPI code - it doesn't handle that the
_SRS report doesn't report it. Even ignoring the problems with
older SBs which would need some special handling code]
The BIOS returns fixed IRQs in the _PRS method when system is in APIC mode if SB is after
+VT8235.
(IDE-IRQ20, USB-IRQ21, Audio and Modem-IRQ22, LAN-IRQ23)
2) The _CRS method is hardcoded to return 0 ALWAYS for link devices in APIC mode.
We feel strange for this situation. This control method will check internal device's
+interrupt line (Rx3C of PCI configuration) to return current IRQ setting.
Will it be possible in Linux kernel driver which will reset the Rx3C to zero ?
<<
Forcing PIC mode will at least make it work. Of course it would be
better to fix the ACPI code to handle all this properly.

Thanks. This is interesting. Looking at the IRQ probing output:
> hdc: IRQ probe failed (0x3cfa: 0). Guessing at 15
The interesting parts are the 0x3cfa and the 0:
- the "0" means that we literally didn't see any interrupt at all during
the autoprobing. Sometimes autoprobing fails because we see _multiple_
interrupts, but that wasn't the case here.
- 0x3cfa is the "probe cookie", which tells which irq's were free to be
probed. That's
1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
and what's interesting is that irq 15 wasn't even probed at all (14
wasn't either, but that's easy to explain: we took that when we probed
and registered ide channel 0 earlier. irq 0 and 2 are special - timer
and cascade respectively).
So for some reason irq 15 has already been reserved. Somebody has already
registered IRQ 15 _before_ we probe for it for that hwif. And:

this shows that the claimer of the irq is the IDE layer itself.
But why has the IDE layer already claimed that interrupt?

Interesting and good in the sense that this is another clue. Why does ACPI
interrupt routing cause the IDE layer to register irq 15 too early?
Both the PIRQ routing code and the ACPI code give irq3 to the other IDE
chip. So why has the IDE stuff registered _another_ irq15 earlier?
I don't see it.. Len, Bartlomiej, do you see anything?
Marco, can you try this appended (very very stupid) patch with ACPI on, so
that we can see where irq15 gets registered? It won't fix anything, but
I'm confused by why IRQ 15 has been registered before we probe for it..
Thanks,

Oops.
I read your report lazily, and didn't do it right. I just noticed that it
isn't actually irq3 and the raid controller at 0:0f.0 that is the problem
at all: the problem is the regular legacy stuff on 0:0f.1: hdc/hdd that is
on irq15.
The IRQ probe for hdc fails, for some silly reason.
But we actually correctly _notice_ that it's on irq15, so I
Note how we say:
kernel: hdc: IRQ probe failed (0x3cfa)
but then a few lines later we _have_ figured it out and say
kernel: ide1 at 0x170-0x177,0x376 on irq 15
The problem _appears_ to be the fact that we already registered irq15 for
the IDE driver, which will cause the probe to fail (you can't probe
something that is already in use).
Can you try this patch, and see if it makes a difference? I'd also like to
see the full "dmesg" output (regardless of whether it works or not).

Can you enable DEBUG in "arch/i386/pci/pci.h" and ACPI debugging and then
report what the system says at bootup both with ACPI enabled, and with
"pci=noacpi".
For some reason the system decides that your IDE controller is on irq3,
which is clearly wrong. It's on irq15, but somebody told the PCI layer
otherwise.
