Subject: pcmcia problems with IDE & cardbus


hi,

I've been trying to get a CompactFlash act as an IDE-drive, 2nd or 3rd
ide-channel, that is, IDE1 or IDE2 resp. Didn't work. Seems to be driver
related.

I downloaded 2.4.18 and pcmcia-3.1.31, from the later I got "ide_cs.o"

The hardware I am using a a two socket PCI to PCMCIA bridge:

hale-bopp:~ # cat /proc/interrupts
[...]
10: 1 XT-PIC Texas Instruments PCI1221, Texas Instruments PCI1221 (#2)


when the init-script starts the pcmcia modules + cardmgr, the following
messages will appear in the kernel-log:

"unable to get IRQ 10" is somewhat funny, since IRQ-10 is used by
the cardbus device. what I don't understand is if the IDE-drive
sould get its own interrupt or not.

"ports already in use" doesnt go away even when I remove all IDE-drives
(one CDROM, that is ;-) from ide1 and try to have the CompactFlash as
2ndry IDE (the message would then read: ide1: ports alread yin use,
skipping probe).

and finally an ugly detail: when removing the ComapctFlash and
unloading pcmcia, ide_cs will still have the ioport-ressources
clailed form /proc/ioport. seems there's a call to *_unregister
missing.

Apart from your problem I finally found out that all dldwd_* stuff in 2.4.18
has been renamed to orinoco_*, so pcmcia-3.1.31 is not usable with 2.4.18...

Gunther,

I gave this the heads up and verified a long time ago.
I am puzzled why this has not been adopted.
It at least made it into 2.5.3.

Marcelo, please take this fix!

The card should (must) share the PCI interrupt with the CardBus bridge
device. However, the IDE driver assumes that it should have exclusive
use of the interrupt, because it doesn't believe that this is a PCI
IDE device (well, it is sort of an ISA IDE device sitting behind a PCI
bridge).

The ide_cs driver does call ide_unregister(). The problem is that the
IDE driver doesn't clean up properly if you hot-eject an interface
that has active devices associated with it. Use "cardctl eject"
before you eject an IDE card.

Err what?

Why would the names of functions in the orinoco_cs driver affect the
usability of the pcmcia-cs package on a particular kernel?

I think you're doing something wrong. The only circumstance I could
imagine this making a difference is if you're trying to mix some of
the orinoco modules from the kernel tree with other orinoco modules
from the pcmcia-cs tree.

Did you read my explanation?

You've somehow ended up loading the hermes module from the 2.4.18
kernel tree, and the orinoco_cs module from the pcmcia-cs package.
"modprobe" is probably getting confused by having several modules with
the same names, in different directories.

If you use just the pcmcia-cs modules, (or just the kernel modules),
then everything should work fine on 2.4.18.
