I would suggest going to the latest 2.6.10 kernel.  I have it running
with several ethernets running on all the 82xx processors.=20

I ported it to the Embedded Planet ep8260 board with FCC3, ep8248 board
with FCC1 and FCC2 and ep8280 with FCC2 and FCC3.  I had to make very
little, if anything, to get it to work.  I did not try 2.6.9.  I am
currently using 2.6.10-rc3 which I believe after the last merge is now
2.6.10.  I did practically nothing to get all of these to work.=20

Hi all

I wish to discuss some strange issues that I faced with respect to the Linux
2.6.8 kernel (downloaded from kernel.org). Firstly, I wish to know whether
this has been known to work on an MPC8260 PowerPC target.

Secondly, when I tried to compile the Linux kernel with my toolchain (built
with Dan Kegel's crosstool for the PowerPC 603e core, which is what my
processor has), I got some errors which I found to rather queer after
investigation. Firstly, let me state the errors that I got:

------------------------------------------------------

  LD      init/built-in.o
  LD      .tmp_vmlinux1
arch/ppc/8260_io/built-in.o(.text+0x103c): In function `mii_queue_relink':
arch/ppc/8260_io/fcc_enet.c:1254: undefined reference to `schedule_task'
arch/ppc/8260_io/built-in.o(.text+0x1074): In function `mii_queue_config':
arch/ppc/8260_io/fcc_enet.c:1263: undefined reference to `schedule_task'

------------------------------------------------------

On further investigation, I find that 'schedule_task()' is simply not
defined anywhere in the 2.6.8 kernel sources. This is quite wierd! However,
it is defined in a file 'context.c' (linux-src/kernel) in the 2.4.27 kernel
sources, which we were using earlier. How is it that a function is being
called but its definition has been removed from the sources?

Another such example is with the structure 'tq_struct'. It is referred to in
the file 'fcc_enet.c' (linux-src/arch/ppc/8260_io) but it's not defined
anywhere! Again, after checking in the 2.4.27 sources, I find that it's
defined in the file 'tqueue.h' (linux-src/include/linux)!

A third thing is that the 2.4.27 kernel source file 'uart.c'
(linux-src/arch/ppc/cpm2_io) is not present in the corresponding folder in
the 2.6.8 source (linux-src/arch/ppc/8260_io). There is one 'uart.c' in the
folder '8xx_io', but it doesn't get compiled during the kernel build
process. Will my UART work correctly with this build?

Can someone please tell me if there's some explanation for this that I'm
unaware of? Which would be the proper forum to report this? Again I would
like to ask: Has the 2.6.8 kernel been tested successfully on the MPC8260
PowerPC platform?

Lastly, where can I get the latest stable Linux kernel source for the
PowerPC platform?

Regards

Vijay Padiyar
