I'm trying to get a TI pci cardbus bridge working on a TXPro/TX-Two based
board.
With the normal PCI configuration methods no IRQ's ever get routed to the
board afaict. Using pci=biosirq oops's as soon as it tries to assign an
irq to a device.
I'm using 2.4.9 patched for lvm-1.0.1-rc1 and ext3-2.4-0.9.6-249. The
same occurs on vanilla 2.4.9
I'm using the pcmcia modules from pcmcia-cs-3.1.28 and linux-wlan-ng-0.1.9
because the kernel modules don't provide the features I need for my
application. The kernel yenta_socket doesn't load because it
cant get the irq's routed.. The linux-wlan and pcmcia-cs drivers do get
loaded but don't actually get the irq's routed.
The relevant config:
CONFIG_PCI=y
# CONFIG_PCI_GOBIOS is not set
# CONFIG_PCI_GODIRECT is not set
CONFIG_PCI_GOANY=y
CONFIG_PCI_BIOS=y
CONFIG_PCI_DIRECT=y
CONFIG_PCI_NAMES=y
# CONFIG_EISA is not set
# CONFIG_MCA is not set
# CONFIG_HOTPLUG is not set
# CONFIG_PCMCIA is not set

[ endless stream of oopses snipped ]
c00fde03 is not in my System.map, c0107050 is inside show_trace.
I've narrowed down the problem to an lcall inside pcibios_set_irq_routing,
it goes into the call and oopses from there.
__asm__("lcall (%%esi); cld\n\t"
"jc 1f\n\t"
"1:"
: "=a" (ret)
: "0" (PCIBIOS_SET_PCI_HW_INT),
"b" ((dev->bus->number << 8) | dev->devfn),
"c" ((irq << 8)) | (pin + 10)),
"S" (&pci_indirect));
Some poking around shows that %esi remains unch, %eax and %ebx are
clobbered and %ecx is untouched. It does appear that the inputs are
correct for the call. I can't confirm that the call address c02140cc, or
the device function 0x20 is correct however.
The card is attempting to take irq 11, if I swap things around to get it
to take 10, %ebx goes to dde3.
The board is an Amptron PM-9600 which uses a TX-Two labeled chipset,
really its the same as a TXPro/ALi 1531, infact you can use many TXPro
bios's with it. The bios date is 5/13/99 S, it's the last bios update for
this board. A PC Chips m565 (402s) bios also works but has the same
results.
No bios settings have an effect.
I'll be glad to poke around some more or test changes.
Do I have any hope of getting irq routing over this bridge working on this
board?
Thanks,
John..
