Ah, right, thanks. I changed it to:
if (nr_ioapics && !skip_ioapic_setup)
return;
Is that better?

Yes, I was worried about that, too. I added it back.
> ps. we need to fix this on 2.4 also.
Here's yet another iteration for 2.6. If this works OK,
I can back-port it to 2.4.
In PIC mode, some Via devices update IRQ routing when
PCI_INTERRUPT_LINE is written. So if we've updated the
device's IRQ, we also need to update PCI_INTERRUPT_LINE.
This also restores the mysterious "udelay(15)" before the
update because we don't know whether it's necessary and
haven't seen an argument for its removal.

Re: [ACPI] Re: Fw: Anybody? 2.6.11 (stable and -rc) ACPI breaks USB
Bjorn, I like how pci_fixup_device() invokes the quirk when we want at pci_enable_device() time w/o cluttering the code with VIA specific hooks. I think you've also identified an improvement by checking acpi_irq_model -- as the PCI config space IRQ register is defined only in PIC-mode -- so one must assume that the quirky via HW can't depend on us writing reserved bits for IRQs > 15. But checking skip_ioapic_setup in the non-ACPI case isn't quite right. This is set for "noapic". But it is not set in the PIC-mode case where the kernel supports IOAPIC but the hardware does not -- in that case the quirk would erroneously exit. Also, the original quirk_via_irqpic() had a udelay(15) before the write -- I have no idea if that was significant or not -- maybe soembody else on the list does -- as none of us have VIA documentation... thanks, -Len ps. we need to fix this on 2.4 also. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Good. Thanks for all the help in refining this!
Andrew, can we put this in -mm?
BTW, I also have a report that this fixes a problem like
the following. I've had several similar reports that initially
seemed to be related to "pci=routeirq", so I'm optimistic that
fixing this Via problem will help several folks.

OK. Try this one for size. It differs from what's currently in
the tree in these ways:
- It's a quirk, so we don't have to clutter acpi_pci_irq_enable()
and pirq_enable_irq() with Via-specific code.
- It doesn't do anything unless we're in PIC mode. The comment
suggests this issue only affects PIC routing.
- We do this for ALL Via devices. The current code in the tree
does it for all devices in the system IF there is a Via device
with devfn==0, which misses Grzegorz's case.
Does anybody have a pointer to a spec that talks about this? It'd
be awfully nice to have a reference.
Grzegorz, can you check to make sure this still works after all the
tweaking?

I think it's good to limit the scope of the quirk as much as
possible because that makes it easier to do future restructuring,
such as device-specific interrupt routers.
The comment (before quirk_via_acpi(), nowhere near quirk_via_irqpic())
says *on-chip devices* have this unusual behavior when the interrupt
line is written. That makes sense to me.
Writing the interrupt line on random plug-in Via PCI devices does
not make sense to me, because for that to have any effect, an
upstream bridge would have to be snooping the traffic going through
it. That doesn't sound plausible to me.

I feel we concerned too much. Changing the interrupt line isn't harmful,
right? Linux actually ignored interrupt line. Maybe just a
PCI_FIXUP_ENABLE(PCI_VENDOR_ID_VIA, PCI_ANY_ID, quirk_via_irq) is
sufficient.

This just feels like a sledgehammer approach, i.e., we're
programming PCI_INTERRUPT_LINE in more cases that we actually
need to. I especially don't like that any Via device with
devfn==0 triggers the quirk. That doesn't seem like the
right test if we're really looking for a Via bridge.

Yes, that's what I meant by the above probably not being sufficient.
The main thing the debug patch did was to move the write to after
the IOAPIC programming. (And I think it added back the mysterious
udelay().) My point is that the write could just as easily be done
in a pci_enable fixup, because that also happens after the IOAPIC
update.
The quirk would have to be something like this:
static void __devinit quirk_via_irq(struct pci_dev *dev)
{
if (!via_interrupt_line_quirk)
return;
/* update PCI_INTERRUPT_LINE */
...
}
DECLARE_PCI_FIXUP_ENABLE(PCI_ANY_ID, PCI_ANY_ID, quirk_via_irq);
with a PCI_FIXUP_HEADER quirk that sets via_interrupt_line_quirk when
we find a Via bridge.
But I'm uneasy even about this -- what if there are multiple bridges,
with only one of them being a Via? Why would we want to apply this
quirk to the devices under the non-Via bridges? Wouldn't it be better
to search up the hierarchy of each device, looking for a Via bridge,
and apply the quirk only if we find one?

VIA bridges allow for IRQ routing updates by programming
PCI_INTERRUPT_LINE, so it is supposed to work even if we do it for all the
devices, so it appears to be a board/bios specific problem.

This looks like it'll only affect the PCI device associated with the
listed south bridges, which might break systems which relied on the per
device setting. Your 'debug' patch actually made sense to me, that is,
moving the PCI_INTERRUPT_LINE fixup at gsi register.
Thanks,
Zwane

The patch I sent you was just for debugging -- I think we can come
up with a cleaner fix.
I think the INTERRUPT_LINE write should actually happen in a
pci_enable_device() fixup. Then we could get rid of all gunk
in pirq_enable_irq() and acpi_pci_irq_enable().
Something like the following will probably work for you, Grzegorz,
but I expect that it won't be enough for somebody with a Via
northbridge.
The previous quirk_via_bridge() says "if the system contains any
Via device with devfn==0, then do the INTERRUPT_LINE fixup for
every PCI device in the system, regardless of what the Via
device is or where it is relative to the current device."
That seems awfully suspicious to me. So the following is
probably safe as far as it goes, but not sufficient for all
cases.

RE: [ACPI] Re: Fw: Anybody? 2.6.11 (stable and -rc) ACPI breaks USB
Hi,
This issue is quite interesting. We removed all specific VIA quirk
recently and apply a generic VIA quirk. But in this case, the MCH 00:0.0
is from AMD, and the ISA bridge and built-in devices are from VIA, this
means VIA quirk is useless, since it takes action only when the MCH is
from VIA. We possibly should enable VIA quirk if a VIA ISA bridge is
found instead of a VIA MCH found, but Bjorn's method seems ok.
If you want to put the patch into kernel, please also change the '
pirq_enable_irq' case.
Thanks,
Shaohua

You have:

(rev 40)

:00:07.3 USB Controller: VIA Technologies, Inc. USB (rev 1a) (prog-if 00

and we apparently ran the quirk for 07.2 and 07.3. I wouldn't
have thought those would have one of the above device IDs. The
"lspci -vvn" should tell us for sure.
2.6.11 removed that quirk and runs quirk_via_bridge() for
all VIA devices, but only sets via_interrupt_line_quirk if
(pdev->devfn == 0), which you don't have. So that's why
my patch didn't do anything.
Also two more questions:
1. What is VIA fixup? Is it some hardware bug? Or BIOS problem? Why is it
needed? On what hardware / software it is needed?
I really don't know much about the VIA fixup. I just noticed
that we seem to be doing it slightly differently in 2.6.11 than
we did in 2.6.9, and thought maybe it was related to your problem.
Here's a changeset that has a couple pointers:

Re: [ACPI] Re: Fw: Anybody? 2.6.11 (stable and -rc) ACPI breaks USB
Can you do an "lspci -vvn"? I'm looking at quirk_via_irqpic() in
2.6.9, which is what printed this:
> >PCI: Via IRQ fixup for :00:07.2, from 9 to 10
> >PCI: Via IRQ fixup for :00:07.3, from 9 to 10
but it looks like it should only run for PCI_DEVICE_ID_VIA_82C586_2,
PCI_DEVICE_ID_VIA_82C686_5, and PCI_DEVICE_ID_VIA_82C686_6.
You have:
:00:07.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South]
(rev 40)
:00:07.1 IDE interface: VIA Technologies, Inc.
VT82C586A/B/VT82C686/A/B/VT8233/A/C/VT8235 PIPC Bus Master IDE (rev 06)
:00:07.2 USB Controller: VIA Technologies, Inc. USB (rev 1a) (prog-if 00
[UHCI])
:00:07.3 USB Controller: VIA Technologies, Inc. USB (rev 1a) (prog-if 00
[UHCI])
and we apparently ran the quirk for 07.2 and 07.3. I wouldn't
have thought those would have one of the above device IDs. The
"lspci -vvn" should tell us for sure.
2.6.11 removed that quirk and runs quirk_via_bridge() for
all VIA devices, but only sets via_interrupt_line_quirk if
(pdev->devfn == 0), which you don't have. So that's why
my patch didn't do anything.

I really don't know much about the VIA fixup. I just noticed
that we seem to be doing it slightly differently in 2.6.11 than
we did in 2.6.9, and thought maybe it was related to your problem.
Here's a changeset that has a couple pointers:

I have no idea about this. But it's only a couple hundred bytes.
So here's another patch to try (revert the first one, then apply this).

Good point.
Thanks for posting the 2.6.9 output as well. It contains this:
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 10
ACPI: PCI interrupt :00:07.2[D] -> GSI 10 (level, low) -> IRQ 10

In 2.6.9, we did all the ACPI IRQ routing early, then did the
Via IRQ fixups. In 2.6.11, ACPI IRQ routing is done only when
a driver claims a device, and the Via IRQ fixup is done a little
differently. In fact, the Via fixup happens before we twiddle
the IOAPIC, where in 2.6.9, it happened after.
Can you try the attached patch to see whether it makes any

Good point.
Thanks for posting the 2.6.9 output as well. It contains this:
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 10
ACPI: PCI interrupt :00:07.2[D] -> GSI 10 (level, low) -> IRQ 10

PCI: Via IRQ fixup for :00:07.2, from 9 to 10

In 2.6.9, we did all the ACPI IRQ routing early, then did the

Unfortunatelly its 3 years ABIT KG7-Lite. I was begging ABIT for update (to fix some other problems with new CPUs) some time ago but they refused to make new BIOS for this board. And I have the newset release. And if this is a BIOS issue then why it worked for 3 years with all kernels up to at least 2.6.9 (only -mm kernels had some problems with USB and other subsystems since I think 2.6.3-mm? or something like that - I stopped using them soon after)? BTW. My mainboard manual says: "PCI-4 and USB controllers share an IRQ" (the manual is on www.abit.com.tw so you can check it). But ACPI is telling us they're on IRQ10, which seems like a BIOS bug. Maybe this is just some off-by-one in recent kernels? ;-) Can you also post the complete dmesg log without "acpi=off"?

Can you check to see whether there are any BIOS updates available for your box? It looks to me like your USB controllers are wired to IRQ9, and that's how the BIOS is leaving them configured. But ACPI is telling us they're on IRQ10, which seems like a BIOS bug. Can you also post the complete dmesg log without "acpi=off"? There might be an ACPI interrupt link device for the USB controller, and maybe there's something wrong there. > My log (2.6.11 without acpi=off): > Mar 2 23:36:56 kangur USB Universal Host Controller Interface driver v2.2 > Mar 2 23:36:56 kangur ACPI: PCI interrupt :00:07.2[D] -> GSI 10 (level, > low) -> IRQ 10 > Mar 2 23:36:56 kangur uhci_hcd :00:07.2: UHCI Host Controller > Mar 2 23:36:56 kangur uhci_hcd :00:07.2: irq 10, io base 0xc800 > Mar 2 23:36:56 kangur uhci_hcd :00:07.2: new USB bus registered, > assigned bus number 1 > Mar 2 23:36:56 kangur hub 1-0:1.0: USB hub found > Mar 2 23:36:56 kangur hub 1-0:1.0: 2 ports detected > Mar 2 23:36:56 kangur ACPI: PCI interrupt :00:07.3[D] -> GSI 10 (level, > low) -> IRQ 10 > Mar 2 23:36:56 kangur uhci_hcd :00:07.3: UHCI Host Controller > Mar 2 23:36:56 kangur uhci_hcd :00:07.3: irq 10, io base 0xcc00 > Mar 2 23:36:56 kangur uhci_hcd :00:07.3: new USB bus registered, > assigned bus number 2 > Mar 2 23:36:56 kangur hub 2-0:1.0: USB hub found > Mar 2 23:36:56 kangur hub 2-0:1.0: 2 ports detected > My log (2.6.11 with acpi=off): > Mar 3 01:45:48 kangur USB Universal Host Controller Interface driver v2.2 > Mar 3 01:45:48 kangur PCI: Found IRQ 9 for device :00:07.2 > Mar 3 01:45:48 kangur PCI: Sharing IRQ 9 with :00:07.3 > Mar 3 01:45:48 kangur PCI: Sharing IRQ 9 with :00:0b.0 > Mar 3 01:45:48 kangur uhci_hcd :00:07.2: UHCI Host Controller > Mar 3 01:45:48 kangur uhci_hcd :00:07.2: irq 9, io base 0xc800 > Mar 3 01:45:48 kangur uhci_hcd :00:07.2: new USB bus registered, > assigned bus number 1 > Mar 3 01:45:48 kangur hub 1-0:1.0: USB hub found > Mar 3 01:45:48 kangur hub 1-0:1.0: 2 ports detected > Mar 3 01:45:48 kangur PCI: Found IRQ 9 for device :00:07.3 > Mar 3 01:45:48 kangur PCI: Sharing IRQ 9 with :00:07.2 > Mar 3 01:45:48 kangur PCI: Sharing IRQ 9 with :00:0b.0 > Mar 3 01:45:48 kangur uhci_hcd :00:07.3: UHCI Host Controller > Mar 3 01:45:48 kangur uhci_hcd :00:07.3: irq 9, io base 0xcc00 > Mar 3 01:45:48 kangur uhci_hcd :00:07.3: new USB bus registered, > assigned bus number 2 > Mar 3 01:45:48 kangur hub 2-0:1.0: USB hub found > Mar 3 01:45:48 kangur hub 2-0:1.0: 2 ports detected - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
