ibm emac driver update

ibm emac driver update

[Simon Haynes]

I am running a Ebony board with linux-2.6.12-rc1 and I amd having intermittent 
network problems. Having searched the archives it would seem that the driver
for the IBM EMAC is buggy ? 

I have tried to patch my kernel with 

http://kernel.ebsname.net/emac/4xx_napi_emac.diff

I believe this is almost a total driver re-write. Is this correct ?

After having a couple of problems applying the patch, Kconfig and 
ibm_emac_core.c. I fixed up the original code and applied the patch.

On compilation the build fails with missing references to kzalloc,
which I guess I could easily fix with kmalloc and memset. 

However there is also an undefined field,  dcr_base, in the ocp_func_mal_data
structure.  This structure appears to be defined in include/asm/ibm_ocp.h and 
this file does not appear to be changed by the patch. I guess this patch is 
for a later kernel.

Can anyone point me in the direction of a suitable patch for this kernel ?

Many Thanks

Simon.

I'm not sure about 2.6.12-rc1, but you can try GIT tree/patches at 
http://kernel.ebshome.net. 

Hint: you can assume that in addition to emac_3-2.6-28.diff, there are 
also emac_3-2.6-NN.diff (NN < 28) on my website which were made for 
earlier kernel versions :).

Alternatively, you can backport all relevant stuff from current 2.6 or 
you can pay someone to do this for you.

Eugine,

Thanks for the reply. I am not familiar with git and I do not
have it installed on my system. I have looked for rpms and
tried to build git. It seems that I will need to make a lot of changes
to my system to get this going.

In a response from Wolfgang he lists a url which can be used to access 
his git tree via a browser. I can not find these patch files on his git tree
but I was wondering if you made the files available in a similar way.

Alternatively can you mail the file to me ?

Or can you tell me if the files are somewhere on

http://www.denx.de/cgi-bin/gitweb.cgi?p=linux-2.6-denx.git

If not I guess I will just have to get all the bits together to run
git and learn how to drive it.

Many Thanks

Simon.

I have eventually got git going. I am not familiar with it but following a 
tutorial I did

git clone rsync://kernel.ebshome.net/linux-2.6-emac.git
cd linux-2.6-emac
git checkout

I then ran find looking for a patches dir and could not find one.

Could you please tell me how to locate the emac_3-2.6-NN.diff files.

Cheers

Simon

Patches have been posted on this list. See the archives.

Hello,
Could you tell me where to set base address and IRQ in kernel?mabe in 
serial.c or correlative head file? I searched the list mails and found 
somebody said there are explanation in DENX CVS LABEL_2003_03_11_2055 to 
LABEL_2003_03_11_2110,but how can I get them?

you can modify serial.c:
static int __init rs_init(void)
{
	my_uart_init();
	....
	....
}

add my_uart_init(), it init OR and BR where your board uart use,
and fill rs_table with IRQ and IOBASE.
