yenta-cardbus IRQ0

Post by Robert Bispin » Sat, 01 Feb 2003 13:00:54



i have been trying to set up a cardbus card on my thinkpad 760ED for about
the last month and it keeps coming up with IRQ0 and telling me it cant find a
irq for pin A. what would be causing this and how do I correct it i have
already tried APCI and it does not work on my laptop so that is no help. I
have compiled SMP into the kernel though I dont have a dual processor (of
course) to gain the added functionality. I have recompiled my kernel about
150 times with different setting hoping it might just be a conflict in the
kernel with no luck.  I looked at the yenta driver it's self and noticed that
it accepts IRQ0 as a valid irq but that appears to mean no irq at all. which
config file would i use to force it to set a irq?

Thanx for any assistanc you might give

Enter your bios and assign one.

But anyway, this could be anything. Most probably unsupported
controller for something. Does the 760 do cardbus? Did you compile for
cardbus? What are you doing about loading the driver (it's handled by
pci hotplug, not pcmcia, as far as I know).

Why?

Eh? SUrely your 760 doesn't have a recent processor?

None. ANd there's nothing wrong with no irq in itself, but it usually
is a symptom of something wrong. You can do your bit with setpci.

Try the i82365 driver.

uhmm, 1th try to upgrade to a newer one, then I experienced the same problem with a
custom board... the problem was triggered by the Base Address too high:

  Region 0: Memory at 10812000 (32-bit, non-prefetchable) [size=4K]

moving id_sel (in the PCI core of the board) in order to obtain a lower bar all worked.

BTW, has anybody there ever heared about such a costraint in the PCI specification ??
Why I got this strange behaviour ???

ok, can you give me some more specifics? i.e how do i do that or what
howto/man etc. (not the kernel part the id_sel part) thanx

I think you can't do that if you are not able to put your hand in the HW.
There's nothing you can do from linux, that I know...

You can take a look to the PCI specification, but i don't think it will aid
you so much...

1. PCI-2-Cardbus bridge, Kernel PCMCIA services and Cardbus

Hi people,

I have a strange problem with virtually all 2.4 kernels,
(tried 2.4.18 to 2.4.20-rc1). I'm developing a driver
for a wireless card for our customer. Since it's a Cardbus
wireless card and my dev machine is a desktop, I'm using
a Ricoh 5c475 based PCI-2-Cardbus bridge.

My problem is that the yenta_socket.o driver (or pcmcia_core.o)
indeed create  Cardbus bus with my device on it, but the BAR's
are all messed up. I get negative len ranges on the MMIO addresses
(0xE7010000 - 0xE7003FFF).

I'm not sure this is a problem in the Kernel PCMCIA drivers, because
even with them not loaded, the Ricoh device (Cardbus bridge) contains
weird bridge resources (offset 0x1C and forward in the PCI
config space headertype 0x02). This doesn't happen only with my
customers wireless card, but with one another different vendors wireless
card too.

I've even tried Alan Cox' 2.4.20-pre10-ac2 patch with no success.

Anyone seen this before and know where I might throw my search lights ?

Thanks,
George.
