VAIO IRQ assignment problem of USB controller

VAIO IRQ assignment problem of USB controller

[Brian Lavender]

I have a Sony VAIO PCG-GR170K laptop with a memory stick which operates
off of the USB controller with device ID 00:1d.2. The laptop has a total
of three USB controllers.  The first two are getting IRQ's, but the third
one is not. Under Win2k, it assigns all three USB controllers IRQ 9. I
checked the bios for USB options, and the only option I could find is to
set a "Non PNP" OS.  I found no other USB options. I am currently using
kernel 2.4.9 from Redhat compiled from the source RPM.  I am guessing
that this must be a problem somewhere in the PCI IRQ configuration.
Any other suggestions aside from downloading 2.4.17?

Here's the code from UHCI that configures the device. It looks like if
it can't see an IRQ, it can't configure the device.

/usr/src/linux/drivers/usb/uhci.c

   2856 static int __devinit uhci_pci_probe(struct pci_dev *dev, const struct pci_device_id *id)
   2857 {
   2858         int i;
   2859 
   2860         if (!pci_dma_supported(dev, 0xFFFFFFFF)) {
   2861                 err("PCI subsystem doesn't support 32 bit addressing?");
   2862                 return -ENODEV;
   2863         }
   2864         dev->dma_mask = 0xFFFFFFFF;
   2865 
   2866         /* disable legacy emulation */
   2867         pci_write_config_word(dev, USBLEGSUP, 0);
   2868 
   2869         if (pci_enable_device(dev) < 0)
   2870                 return -ENODEV;
   2871 
   2872         if (!dev->irq) {
   2873                 err("found UHCI device with no IRQ assigned. check BIOS settings!");
   2874                 return -ENODEV;
   2875         }

Hey Brian,

the mem stick + 2 usb ports my Z505LS work fine with 2.4.16+
(both usb ports have been tested, but the mem stick not [however, it shows
up fine at boot time]).

You might also want to run 2.4.teen because of the new support for the
Sony programmable controller (althought that seems to have gone into 2.4.5)
(under char devices, i believe).

See: http://groups.google.com/groups?q=linux+sony+programmable+controller&hl=en&selm=linux.kernel.20010604153515.A31991%40ontario.alcove-fr&rnum=1

I think I told you about the GVaioControl app that I use for brightness at the
big installfest over the summer, but this seems to actually enable the function
keys.

ps. heh, it's weird seeing people you know on LK :)

I downloaded the 2.4.17-pre3 kernel from Redhat's site with their patches,
and I compiled it. Still having the same problem with the IRQ. Below is
what I get from lspci and dmesg. This time I did not pass the kernel
pci=biosirq which I had done in the past. Is this something that the
bios just isn't reporting or is there some sort of fix I can do?

$ lspci -vv

This is another device that Sony has decided to configure via ACPI.

You'll need to check out the Linux ACPI project, and see about getting
the ACPI IRQ routing patch.

No, I don't know where it's at exactly..  try using google.

Having just this problem occur...  My Sony VAIO R505tsk needed this for
not just the card slot, but the USB too!  (I'm running Sony's update
WinXP bios on it).

Here's the article with the patch:
