pnp missing proc entries?

[Mark Hindley]

Hi,

I have just switched to 2.6 and am trying to resolve and irq conflict
between a sound card and internal modem.

Looking in Documentation/pnp.txt there should be files in
proc/bus/isapnp/<node>/{id,resources,options}.

However all I have is plain node at /proc/bnus/isapnp/<node> that dumps
some binary data.

Is the documentation out of date? I can see the calls to make the
missing nodes in pnp_add_device() but can't find it called from
anywhere. Is this a deliberate omission?

Thanks

Mark

Is the pnp layer complaining about this conflict?  Are you using pnpbios 
support?  Are both the sound card and internal modem isapnp devices?

Thanks for bringing this to my attention.  I'll update the documentation 
soon.

You can access this information through sysfs.

try something like this:
mkdir /sys
mount -t sysfs none /sys

Thanks,

Both are internal -- Rockwell/ALS100. I get no complaints from the pnp
layer, other than a refusal to config one if the other modules is
loaded. Both want to use irq 5. I have pnpbios in too.

I have just fixed a problem with unloading the 8250_pnp module, so am
hoping I can delve into this a bit more.

It seems that pnp is only trying the first config option for the device
and then bailing out if that won't fit with what else is setup.
