No-IDE kernel compile link errors

No-IDE kernel compile link errors

[Hollis R Blanchard]

I've been having this problem recently with 2.2.2 source from kernel.org and
now the NMT vger snapshot:

So I 'make menuconfig'. And since I have a PowerCenter (with no IDE anything),
I turn off all IDE support, in General and Block Devices.

I get the following link error:
arch/ppc/kernel/kernel.o: In function `find_ide_boot':
arch/ppc/kernel/kernel.o(.text.init+0x1ca6): undefined reference to
`pmac_ide_count'
arch/ppc/kernel/kernel.o(.text.init+0x1caa): undefined reference to
`pmac_ide_count'
arch/ppc/kernel/kernel.o(.text.init+0x1cc2): undefined reference to
`pmac_ide_node'
arch/ppc/kernel/kernel.o(.text.init+0x1cc6): undefined reference to
`pmac_ide_node'
arch/ppc/kernel/kernel.o(.text.init+0x1cce): undefined reference to
`pmac_ide_count'
arch/ppc/kernel/kernel.o(.text.init+0x1d06): undefined reference to
`pmac_ide_count'

Awesome. Of course it can't find those symbols - I haven't compiled (and don't
want) any IDE stuff.



When I rerun 'make menuconfig', I find that the IDE stuff has been re-enabled
on me. My other changes were saved, though. Examining the .config file, I find
that CONFIG_BLK_DEV_IDE_PMAC and CONFIG_PARIDE_PARPORT are both set to y.

On a related note, I've always wondered who maintains the Makefiles for the
kernel. Is it communal, and if so, are patches to the Makefiles submitted just
like source patches?

Satadru Pramanik had the same error recently:
http://lists.linuxppc.org/listarcs/linuxppc-dev/199902/msg00373.html

There was no solution posted on the list. Maybe he has one?

I suspect that you have CONFIG_PARPORT=y and this doesn't work without
some of the IDE stuff. It's certainly a bug in the config files, like so
many others.

I think this is a problem of some defconfig or config.in file, and these
are changed whenever a driver is introduced. It looks to me that nobody
takes them very seriously. It took years to fix the xconfig stuff. I
tried to understand it once, but it is a horrible mess of self-modifying
spaghetti code.

A quote from drivers/block/Config.in which may be relevant to your
problem:

# Paride Doesn'T Need Parport, But If Parport Is Configured As A Module,
# Paride Must Also Be A Module.  The Bogus Config_Paride_Parport Option
# Controls The Choices Given To The User ...

The CONFIG_PARIDE_PARPORT is just a "test" variable, it doesn't turn
on/off anything in the code, just when the config stuff is going on.  From
what I remember of drivers/block/Config.in, that's prolly a good thing
that it's set.

It sounds like you accidently set the CONFIG_BLK_DEV_IDE to Y in the
arch-spec area (where early BootX Text and TotalImpact card support is).
This ugliiness is fixed by one of the ide patches in the patches dfir on
nmt.

I disabled all IDE everythings (I swear), including "Support for PowerMac IDE
devices (must also enable IDE)" in General setup. Note that when I disable
this and re-run menuconfig, it has been enabled again.

Also, even when I comment out all Makefile options that include the string
"IDE", I still get that link error. I (perhaps naively) assumed there's kernel
code that should be behind a #ifdef IDE but isn't.

I eventually gave in and just enabled the damn IDE stuff. Compiles on my
PowerCenter 132 take a lot longer then I'd like, and to have them fail every
time is very frustrating. This is not the machine to test this on.

However, since I really don't want anything to do with IDE in my kernel, I'll
hope this gets taken care of - or do the NMT patches mentioned fix it? FWIW, I
got my sources from NMT (the 3/7 vger snapshot).

The NMT snapshots are just what's in vger.  This patch is not.  Goto the
patch/pmac-ide-module or ide-module dir, grab that and try again.  I
think this is the same thing I ran into when I was running the iMac w/
nfsroot and had ide modularized for fun.

I seem to recall having read something about the 2.2 kernels not compiling if 
IDE isn't set.  I had the same problem, so I just compiled in IDE support, 
even though I have no IDE devices or bus.

Feel free to correct me if I'm wrong.

Please try
ftp://linuxppc.cs.nmt.edu/pub/linuxppc/patches/non-pmac-ide/ide.diff
Then rm your .config and try again.  If this works I'll bug Cort <g>

I've had the same problem.  The only way I could get rid of all traces of IDE was to run 'make config' and tediously step through each kernel option.  A pain but it worked.

A useful trick if you just want to change one kernel option is to edit
your .config to delete that particular line, then say `make oldconfig'.
It will run through and just ask you about the option you deleted.
(Don't just change the line to what you want, because make config does
several other things like setting up autoconf.h and include/config.)
