ppc linux kernel 2.4.4 for ppc440/EBony using ELDK 2.0.2?

ppc linux kernel 2.4.4 for ppc440/EBony using ELDK 2.0.2?

[Xiaolong Li]

Hello:

I am currently working on IBM's 440GP Ebony evaluation board,
trying to run Linux on it. I installed ELDK 2.0.2 on RedHat 7.1,
and sucessfully compiled ppcboot, which runs smoothly on 440GP.

Now I am trying to build a Linux kernel 2.4.4 (which is included in
ELDK 2.0.2), but I see some errors regarding to mfdcr/DCRN_EXISR.

My question is: have anybody successfully built a Linux 2.4.4 kernel
for ppc 440GP/Ebony board? what changes did you make to the
kernel source to have it work? is there any patch available?

Thanks,

El

The 2.4.4 LInux kernel as included in this version of the ELDK is not
suitable for 4xx systems. Please use  the  linuxppc_2_4_devel  kernel
tree instead; see http://penguinppc.org/dev/kernel.shtml

Randal said it would be tough to do in sed. He didn't say  he  didn't
understand  sed.  Randal  understands sed quite well. Which is why he
uses Perl. :-)         - Larry Wall in <7874@jpl-devvax.JPL.NASA.GOV>

Thanks Wolfgang.

I've got the linuxppc_2_4_devel tree, made config for 440/Ebony,
then when I compiled the kernel, I got this problem:

This is indeed weird, how could ppc_4xx-gcc not find "stdarg.h"? the same
version
still works for the stable linuxppc-2.4.4, and I saw
/home/lxl/linuxppc_2_4_devel/include/linux/kernel.h
also has #include <stdarg.h> but ppc_4xx-gcc has no problem finding
stdarg.h.
I doubt checked and made sure I have stdarg.h at
$(eldk_root)/ppc_4xx/usr/lib/gcc-lib/ppc-linux/2.95.4/include/stdarg.h

Anybody has this problem? or has any idea how I can make it work?

Thanks,

El

Search EBony and ELDK in this mail list. THis topic has been discussed for several times. A short answer is as follows.

#kbuild_2_4_nostdinc	:= -nostdinc -iwithprefix include
kbuild_2_4_nostdinc	:= -nostdinc $(shell $(CC) -print-search-dirs | sed -ne 's/install: \(.*\)/-I \1include/gp')

This is a known problem. We use the following modification to the top
level makefile  in  our  version  of  the  source  tree  (see  module
linuxppc_2_4_devel on our CVS server):
