atm8260-1.0.1

[shagitgy]

Hi
I have an mpc8260 board and Linux running on it (I uses Lineo's BSP with kernel
2.4.1). I want to run the atm8260-1.0.1 on my board. My phy is s/uni pm 5350-
rc.
My question is:
Can I use the package from:  https://sourceforge.net/projects/atm8260/ as is?
How can I use it? should I compile it with the kernel, or can I insert it as a
loadable module (I didnt find the module_init() call).

Any answer will be very helpful!!!
Thanks a lot,
Hagit Guy

You can use it. Just unpack the files in arch/ppc/ppc/8260_io.

Add this line to the Makefile in that directory:

obj-$(CONFIG_UTOPIA)	+= mpc8260sar.o mpc8260sar_detect.o intpool.o mpool.o \
			   risctimer.o mm.o cpmtimer.o utopia.o debug.o mpc8260iop.o

and this line to Config.in (same directory):

bool 'CPM FCC ATM/UTOPIA' CONFIG_UTOPIA

For the kernel config file you need to enable at least these options:
CONFIG_ATM=y
CONFIG_UTOPIA=y

PS. Check the #defines in the unpacked files if they are correct for your
situation.

You can't use it as a loadable module, just compile it directly in the kernel.

Hello all.

I am using the mpc8260ads board running the 2.4.4 kernel and the phy is
also the pm5350.

In reference to the message below, why can't you use the code as a
loadable module?  I have tried it this way, and it does eventually
compile and insert, although it doesn't do much else at the moment.

I have also tried to compile the code into the kernel, but that is
proving to be more difficult than just doing what you stated below.
There are a whole lot of undefined reference errors.

By the way, the module_init() is in the file mpc8260sar_detect.c.

Please let me know why you say that it must be compiled into kernel, and
also any other steps or defines that I may need.

You also don't make any mention of the suni/phy code below. How should
that be compiled in or included?

Thank you.

CONFIG_ATM=y
CONFIG_UTOPIA=y

You also need to set the kernel configuation variable:
CONFIG_ATM_VADS=y

and extend the Makefile with vads_phy.o:
obj-$(CONFIG_UTOPIA)	+= mpc8260sar.o mpc8260sar_detect.o intpool.o mpool.o \
			   risctimer.o mm.o cpmtimer.o utopia.o debug.o \
			   mpc8260iop.o vads_phy.o

Allocation and de-allocation of buffer descriptors and other buffers in
dual-port memory might give problems.

Such as? I compiled it without problems (but without vads_phy.o).

Hello Willy.

Thanks for the prompt reply.

Did that, and also what's below. One difference however, is that there
is no risctimer.c file to create an object file, only the risctimer.h
which is included in some files. I also added the suni.o object to the
list of objects below (the suni.c and suni.h files are included in the
dir). Is that correct?

I was getting reference errors referring to 'debug_print' but they were
originating from the unrelated uart.c file.

I did eventually get it to compile by not using that function and fixing
some other errors on my part.

At the moment, on boot up of the kernel, it says that:

utopia (itf 0): no signal

after a couple of read and write to the suni.

Still trying to debug this, but thanks for the help so far. I woiuld
appreciate any further advice on your part.
