[PATCH] Wrong IRQ for USB on Sony Vaio (dmi_scan.c, pci-irq.c)

[PATCH] Wrong IRQ for USB on Sony Vaio (dmi_scan.c, pci-irq.c)

[Jan Slupski]

Hi,

I'm writing once more about problem with IRQ assignment 
for Sony Vaio Laptops.

Broken BIOS of these notebooks assigns IRQ 10 for USB,
even though it is actually wired to IRQ 9.

I use PCG-FX240 model of Sony Vaio, but I have proofs of other users, 
that exactly the same problem exists on models:
FX200, FX220, FX250, FX270, FX290, FX370, FX503, R505JS, R505JL
These models use Intel's 82801BA controller, and Phoenix bios.

I wrote the patch that fix this. It is written on example of
patch for HP Pavillion (taken from 2.4.19-pre7-ac1).

This patch was tested on FX240. 
It is build for 2.4.18-pre7-ac1.

Only problem is I don't have DMI Product names for all involved models.
That's why I left pretty general:
  MATCH(DMI_PRODUCT_NAME, "PCG-")

I can help find exact Product Names for all models listed above, but
still new models of Vaio laptops are released with this bug.
I think checking of PCI Vendor & Device number should be enough proof
of broken bios.

If you think it should be tested on all models listed above, I can ask
their owners to do this. (They are now using my previous, even more ugly hack)

Some more description, and logs can be found on my Sony Vaio site:
http://www.pm.waw.pl/~jslupski/vaio/
I can provide any additional data, if needed.

Jan

Too generic. This matches my Z600 for example, which does not have this bug.

I know.
But it PCI id/vendor probably will not match.

But if you think, it's better to add all 12-15 models separately,
why not?
I can start asking for this information...

FX240 will have:
MATCH(DMI_PRODUCT_NAME, "PCG-FX240(UC)")
probably 
MATCH(DMI_PRODUCT_NAME, "PCG-FX240")
is enough.

Do you know any simple tool to retrieve DMI information?
I did it by enabling debug output in kernel, but it would be easier
if I haven't to ask everybody to do thi...

On my machine (Toshiba Satellite Pro 4300 series) running dmidecode
gives me this....

And keeps repeating...

Any hint why?

My Z505JE works perfectly without it. In general Z505's are
known to work.

So...

	if (dev->irq == 9) {
		dev->irq = 9;
	}

Are you sure it's right?

Not sure. For some reason the read at 0x0fffffff was failed by the kernel

I don't know nothing more than this...
I already send an email, and I hope I'll get DMI & PCI informations
for these computers.

Thanks for your USB patch. I got the USB mouse to work
on Sony Vaio PCG-R505JL. I installed RedHat 7.2 first
and the mouse would work for a few minutes and die
(with timeout messages appearing on
/var/log/messages). I did not find the source code for
redhat on the CD. So I ended up compiling the latest
kernel (2.4.18). This is the first time I compiled the
linux kernel, couldn't have been easier!

I had the same USB problem on the Sony PCG-R505JS laptop. Your kernel
patch worked perfectly. At least on the 2.4.18 kernel.

OK.
This line isn't very important. ;)
Other two are!

I just modified HP Pavillion code taht do the same, but 
numbers are other .

Quite some time ago (~ November) Manfred posted a cleanup patch which
fixes this in a more generic way.  You might want to ask him about it.

My FX150 is inflicted when using Sony's WinXP or Win2K BIOS.
The WinME BIOS it shipped with was fine... If you need to identify
problematic machines, I don't think the DMI product name check is
going to be sufficient... better match on BIOS revision also.

Note that the ACPI IRQ routing in the recent (20020329 for me)
ACPI patches is an effective workaround as well. It's turned
on by default when you enable ACPI, which you probably want to do
anyway on most of these laptops to get battery status, poweroff
on shutdown, etc.
