Please send dmesg from both a working kernel and a patched kernel, and
/proc/interrupts from both too.

The most recent VIA IRQ quirk changes have broken various VIA devices for
some users. We are not able to add these devices to the blacklist as they
are also available in PCI-card form, and running the quirk on these devices
brings us back to square one (running the VIA quirk on non-VIA boards where
the quirk is not needed).
This patch, based on suggestions from Sergey Vlasov, implements a scheme
similar to but more restrictive than the scheme we had in 2.6.16 and
earlier. It runs the quirk on all VIA hardware, but *only* if a VIA
southbridge was detected on the system.
Based on suggestions and much investigation from from Sergio Monteiro Basto,
this patch also partially reverts commit
93cffffa19960464a52f9c78d9a6150270d23785 from Bjorn Helgaas. It is not clear
if this was ever the correct fix, see http://lkml.org/lkml/2005/9/26/183
This patch additionally includes a change suggested by Linus in that thread,
where we only quirk devices on non-legacy IRQs.
There is still a downside to this patch: if the user inserts a VIA PCI card
into a VIA-based motherboard, in some circumstances the quirk will also run on
the VIA PCI card. This corner case is hard to avoid.

Andrew, please replace the current -mm patch with this one. The general idea
is that we consider applying the quirk to a lot more devices than we currently
do (more comparable to 2.6.16 and previous), but we add various bail-out
conditions to actually end up applying the quirks much less.
I am fairly confident that we'll still be quirking enough hardware to not
cause any breakage, but we can't be sure until it has seen some testing. This
is compile-tested only.
Stian Jordet: You're on CC due to a discussion linked to from above where
it appeared that you needed Bjorn's patch. Please test this patch against
unmodified 2.6.17 or 2.6.18-rc and let us know if there are any problems.

No more usb for me with this patch :P
When usb is loaded I get this in dmesg:
irq 9: nobody cared (try booting with the "irqpoll" option)
[<c01302d3>] __report_bad_irq+0x2b/0x69

handlers:
[<c024616a>] (acpi_irq+0x0/0x14)
Disabling IRQ #9
and while USB has the same irq in /proc/interrupts now as earlier, usb
doesn't work (or sometimes it does, just dog slow!). Acpi is of course
disabled, so no acpi events neither.
I have to admit, that this computer have some weird behaviour - see
http://bugzilla.kernel.org/show_bug.cgi?id=2874 - but still, it's been
working well for many years now, before this patch. While I do
understand that I seem to be the only one affected by this bug, I hope
someone will help me look into another way to solve my problems if this
patch get applied.
Thanks.

Here dmesg and /proc/interrupts with and without the patch. Both are

Sergio,
Stian appears to be walking proof that quirks are sometimes required in
IO-APIC mode.
My next move would be to modify the patch to not revert Bjorn's changes
(but leave Linus' modification in place, alongside the southbridge
detection). Any thoughts?
Daniel

Hi Daniel, since you ask for thoughts :)
yap, is the obvious conclusion, but no, my bet is one problem with USB
and USB guys could put the USB things working.
I just had remember, my Asrock with VIA8237 and VIA SATA (where I am
write now) is working without quirks and USB guys made a patch, by
coincidence. Since then have been working great.

«(it used to say "if we have an IO-APIC, don't do this" (my patch), now
it says "if this irq is bound to an IO-APIC, don't do this")»
Or my patch or the Linus patch, not both.

About Stian computer, looking for /proc/interrupts
11: 30696 27559 IO-APIC-level uhci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3
have USB on irq 11, with IO-APIC-level, which less acpi is not normal on
low numbers ( <=15 ) be IO-APIC-level, normally is IO-APIC-edge.
Could be a ACPI problem .

I'm not convinced, I'm pretty sure they'd say something like "this
appears to be an IRQ routing problem" and send it somewhere else. I saw
a bug report (introduced by the recent mainline via_irq_quirk() changes)
where exactly this happened, but I can't find it.

Where's the patch?
This report seems to be inconclusive. Your USB problem (comment #19) was
clearly something to do with UHCI itself, whereas Stian's problem is
much more generic and outside the control of the USB HCD: nobody cared
Plus the only issue related to IRQ routing on that bug is triggered by
the closed nvidia driver...

Sorry, I can't figure out what you are trying to say here. Can you
rephrase it?

I think you might be right here. Firstly IRQ 15 is a legacy IRQ,
secondly the existing "&15" thing has no effect on IRQ 15 obviously.

No, there is no bug, think about the logic:
We bail out if dev->irq is higher than 15. Therefore when we get to the
lines of code in question, dev->irq is 15 or less. Performing a logical
AND operation with the value 15 (0xf) is going to have no effect at all.

I beg to differ. Usually APIC interrupts are level triggered. In fact
(just as an example!) most NAPI-based network drivers will not work with
edge-triggered interrupts. Additionally, if my understanding is correct,
multiple devices sharing an edge triggered interrupt is bad news
(interrupts likely to get lost so devices do not get serviced).

the statment was write by Linus on http://lkml.org/lkml/2005/9/27/113
my patch don't quirk any device if we are working on IO-APIC,
Linus simply know if a interrupt is > 15 we are working on IO-APIC and

After a quick test tonight, this patch seems to work nicely for me. (I
know I told Linux that it didn't, don't know what's changed). Does this
fix the problems other people is having as well? If so, that would be
nice :)
Thanks.
