Hi Martin!

While moving from 2.4.0-test9 to 2.4.0 I got the following problem:
Linux thinks my usb controller is on IRQ 12 instead of IRQ 9.
The 'BIOS box' (on boot) still states that usb is on IRQ 9.

Under test9 pci-irq-behaviour was okay for me, but with 2.4.0 I cant
load the usb-modules (the kernel panics and reboots).

I attached the kernel output (with #define DEBUG) and 'lspci -vvx'.

I hope you can help me; otherwise I need a good pointer to pci
configuration specs...


Thanks,
	Robert

No, but that's really interesting..

Your "link" values are in the range 1-4. Which makes perfect sense, but
that's absolutely _not_ what the Linux SiS routing code expects (the code 
seems to expect them to be ASCII 'A' - 'D').

It looks very much like "pirq_sis_get()" and "pirq_sis_set()" in
arch/i386/kernel/pci-irq.c are broken for your setup.

Can you replace them with the following:

	static int pirq_sis_get(struct pci_dev *router, struct pci_dev *dev, int pirq)
	{
		if (pirq <= 4) {
			u8 x;
			pci_read_config_byte(router, 0x40+pirq, &x);
			return (x & 0x80) ? 0 : (x & 0xf);
		}
		printk("Unknown SiS pirq value %d\n", pirq);
		return 0;
	}

and

	static int pirq_sis_set(struct pci_dev *router, struct pci_dev *dev, int pirq, int irq)
	{
		if (pirq <= 4) {
			pci_write_config_byte(router, 0x40 + pirq, irq);
			return 1;
		}
		printk("Unknown SiS pirq value %d\n", pirq);
		return 0;
	}

and see if that changes the behaviour. 

Anybody else with SiS chipsets that want to try the above? Please..

		Linus

In reading the PIRQ specs, and making it work for our board, I thought
about this.  PIRQ states that link is chipset-dependant.  No chipset that I
have seen specifies what link should be.  So, as this case demonstrates, it
may be 'A' - the value the chipset expects, or 1, the logical index.
Either one makes sense, assuming the PIRQ routing code knows what link
means.  Here we see two BIOS vendors/versions that apparently do it
differently for the same chipset.    Grrr.

They _may_ do the same thing for the same chipset, it's just that we don't
know exactly what that "same" thing is.

Ok, I want to see what people have. ANYBODY who has a SiS chipset, please
take 5 seconds to do this as root (yes, you need to be root):

	dump_pirq | mail -s "dump_pirq" torvalds@transmeta.com

and I'm attaching the "dump_pirq" perl script here in this email so that
you don't even have to go to the bother of finding it on the net.

Oh, before you bombard me with email, please check that dump_pirq actually
prints out a PIRQ table. If it says

	No PCI interrupt routing table was found.

followed by a router dump, it's not interesting, and I'd rather not get
a million of those particular emails, ok?

In fact, even if you don't have a SiS chipset, you could do the above. The
exception to that rule is if you have an Intel PIIX router, in which case
we pretty much _know_ that we do the right thing already. 

(And _please_ don't make the subject line anything fancy. I want that
subject line to be "dump_pirq" and nothing else, ok?)

hmmm, would these sis-related pirq problems be related to the current
problems lots of people with a via chipset (at least the apollo pro 133a
chipset) and an smp-enabled kernel are seeing?  currently, people with
this chipset and an smp-enabled kernel have to disable apic if they wish
to use usb.  i've been told a few times that it's a problem with pci irq
routing, but have been able to find a fix.  reports of this problem pop
up every-so-often on the linux-usb list.

here's my dump_pirq output:

Your pirq values are different - they are in the 0x41-0x44 range, like the
old SiS router code assumes. Except for one that has value 0x62, which the
old SiS code actually refused to set because it refused anything that
matches (x & 0x20).

I suspect that the low bits are the "PCI interrupt number", and that the
high bits are some other state information. (ie 0x02, 0x42 and 0x62 all
imply PCI irq INTB, just with different flags set for some reason).

Which one was it you got a PIRQ conflict for before? as it te device at
00:01.00 with the strange "0x62" entry?

How about you try adding the line

	pirq = (pirq-1) & 3;

at the top of both pirq_sis_get() and pirq_sis_set() (with my "alternate"
SiS routines). What happens then?

You've got the pirq setup from hell.

Mind doing that "dump_pirq" thing, preferably run on an _unmodified_ 2.4.0
kernel (ie none of my test-hacks) or on a 2.2.x kernel (that doesn't even
_try_ to do any routing at all - or you can get the same effect by just
making "set_sis_pirq()" always just return 0 without doing anything)?

I don't want to get quantum effects of the observer changing what is being
observed..

Not any better. The thing just moves around, it seems.

I'll think about this, and try to find the SiS irq routing register spec
somewhere..

| Your "link" values are in the range 1-4. Which makes perfect sense, but
| that's absolutely _not_ what the Linux SiS routing code expects (the code
| seems to expect them to be ASCII 'A' - 'D').
| It looks very much like "pirq_sis_get()" and "pirq_sis_set()" in
| arch/i386/kernel/pci-irq.c are broken for your setup.

My ASUS SP97-V complains about PIRQ conflicts so I gave this a whirl
(It is SiS 5598 based)

| Anybody else with SiS chipsets that want to try the above? Please..

Here is my dmesg:

It doesn't.   A diff from the kernel output is following. Maybe it
helps...

Actually, this looks like it _did_ fix something - now the kernel no
longer thinks there is a IRQ routing conflict, so it does seem to be
happier.

Also, while you're unhappy that it assigns irq 12 instead of 9, the pirq
table actually says that it's ok, and again the code seems to say that
this was actually what the system was set up for.

Can you re-iterate what the failure mode is, again? Preferable with this
kernel that definitely looks like it at least agrees with what the BIOS
tells it.

Oh, and please do a "lspci -vvvxxx" as root and send me that as well.

Thanks,

		Linus

I'm not just unhappy to be unable to control the IRQs with the bios
anymore, sym53c8xx doesn't want to share IRQs with the usb
subsystem in this case... (kernel panic (killing interrupt handler(?))
and reboot (rebooting in 60 seconds))

2.4.0-test9 behaviour was different. It really used what the 'bios
box' stated during bootup. - A way to set the IRQ distribution via
kernel-params is okay for me, too.

I'm native German - what is 'failure mode'?

2.4.0-test9 agrees with the bios. [Currently I gave my VGA card (the
S3) an IRQ - without one in the bios 2.4.0-test9 was happy, but 2.4.0
gave it IRQ 8 on its own.]

> Oh, and please do a "lspci -vvvxxx" as root and send me that as
> well.

Okay. For 2.4.0-test9 it's following immediately. After that a
diff of "lspci -vvx" from 2.4.0-test9 to 2.4.0 is included.

Full "lspci -vvx" are in my original post:
http://boudicca.tux.org/hypermail/linux-kernel/latest/0130.html

To mention it: I have also an ASUS SP97 like Aaron Tiensivu. But the
XV version with (unused) onboard VGA.

Further I always see '09' in the Configuration Space at Interrupt_Line
(0x3c) for the 00:01.2 USB Controller. But 2.4.0 says:
  Interrupt: pin A routed to IRQ 12
while 2.4.0-test9 states:
  Interrupt: pin A routed to IRQ 9

Please tell me if it helps te see a "lspci -vvvxxx" from 2.4.0 and
whether I should give some 2.4.0-test?? a try...
I must go to bed now - otherwise my mother kills me when she reads
linux-kernel tomorrow... (-:

Ahhah!

I bet it's the code that goes through all PCI devices, and tries to find
devices that have the same "pirq" (aka "link") value in the tables.

How about this patch? I bet that you'll get a message about pirq table
conflicts. Does USB end up working afterwards?

The patch is good! (:  Currently I'm using 2.4.0 with both the
patch and the alternate pirq-sis-functions.

Here some lines from the kernel after loading usb-ohci:

 usb.c: registered new driver hub
 IRQ for 00:01.2:0 -> PIRQ 01, mask 1eb8, excl 0000 -> newirq=9 -> got IRQ 12
 PCI: Found IRQ 12 for device 00:01.2
 PCI: The same IRQ used for device 00:01.1
 IRQ routing conflict in pirq table for device 00:01.2
 PCI: The same IRQ used for device 00:0c.0
 usb-ohci.c: USB OHCI at membase 0xc8901000, IRQ 9


I send two diffs: the first of "dmesg" from a nonworking 2.4.0 to my
current (working) kernel, the second of "lspci -vvvxxx" from a working
2.4.0-test9 to the working 2.4.0 I use now.


Many thanks, Linus!
			Robert
