Re: [linuxsh-dev] problems with PCI on SH7751 board

[Paul v. G. <pau...@ri...>]

BTW turning on PCI debugging I see the following:

PCI: Starting intialization.
PCI: Using configuration type 1
SH7751 PCI: Finished initialization of the PCI controller
PCI: Probing PCI hardware
Setting IRQ for slot 00:00.0 to 13

PCI: Resource 00000080-000000ff (f=101, d=0, p=0)

PCI: Resource 00002000-00002fff (f=200, d=0, p=0)
PCI: pcibios_allocate_resources pass 1 called
PCI: pcibios_assign_resources called

So it seems my WiFi card has the same IRQ as my Ethernet card (13)  and that
the sound card is having trouble mapping its IRQ.

I added a printk in the else statement and I see a bunch of them. I added:

                        if (!r->start && r->end)
                                pci_assign_resource(dev, idx);
+                       else {
+                               printk("pvg slot %s\n", dev->slot_name);
+                       }

And it produced:

pvg slot 00:00.0
...
pvg slot 00:00.0
...
pvg slot 00:00.0
...
pvg slot 00:00.0
...
pvg slot 00:0f.0
