[Xenomai-help] Compiling Problems for Virtex II pro Board

[Joachim Meyer]

HI

I tried to patch my Kernel 2.6.23 with the aedos patch. But I got the error listet at the end. I was using a Kernel from the Xilinx git tree because there are all the driver included I need. Next I tried to use a the last 2.6.23 Kernel from DENX, which succeded and they also support the ml300 Board but the support for the Xilinx on-chip ethernet is missing. I need that support. So what can I do? The Xenomai patch doesn't only work with the DENX Kernels, right? But where can I look for the error?
Greetings & Thx for all help
Joachim

No, but for anything beyond 2.6.20, the DENX tree is our reference
kernel. So you are -mostly- on your own when using other trees.

arch/powerpc/kernel/entry.S. But the Xilinx PIC code also has to be
adapted to Adeos, which is not done by the original patch, otherwise
this won't work.

Try this patch instead, it fixes the rejects and also makes
arch/ppc/syslib/xilinx-pic.c Adeos-aware:
http://download.gna.org/adeos/patches/tmp/adeos-ipipe-2.6.23-ppc-xlnx-1.6-03.patch

Note: this is a quick hack for the XILINX boards. In theory, this should
work. In practice, I have no idea if it does. The difference between
theory and practice is usually called luck as far as I'm concerned. You
have been warned.

Thank you for taking the trouble making this patch...
I'll try and let you know if it works....

Re: [Xenomai-help] Compiling Problems for Virtex II pro Board

[Joachim Meyer]

Hi Phillipe

Once you gave me a patch to add adeos support to the 2.6.23 Kernel from Xilinx (see old Mail below).
I managed to install Xenomai correctly that time. I didn't made any further tests than those from the testsuite, but they worked fine.
Here's my Question:

What should I do if I want to use a newer Kernel Version at any time? It would be nice to get rid of my dependency to Kernel 2.6.23, because of the special patch. 
Can you give me any information what I can do? Is it hard to fix a normal adeos patch so it works for the Xilinx tree?

Greetings & THX
Joachim

No, but for anything beyond 2.6.20, the DENX tree is our reference

arch/powerpc/kernel/entry.S. But the Xilinx PIC code also has to be
adapted to Adeos, which is not done by the original patch, otherwise
this won't work.

Try this patch instead, it fixes the rejects and also makes
arch/ppc/syslib/xilinx-pic.c Adeos-aware:
http://download.gna.org/adeos/patches/tmp/adeos-ipipe-2.6.23-ppc-xlnx-1.6-03.patch

Note: this is a quick hack for the XILINX boards. In theory, this should
work. In practice, I have no idea if it does. The difference between
theory and practice is usually called luck as far as I'm concerned. You
have been warned.

Adeos/powerpc patches are based on the DENX kernel tree, and looking at the
Xilinx tree, more conflicts are raised over time. I won't say that it's hard to
adapt the patch to the Xilinx tree, but the merge issues are not trivial
anymore, like they were in 2.6.23.

What would help is that more Xilinx bits are sent/merged to mainline or DENX trees.

Next I tried to use a the last 2.6.23 Kernel from DENX, which succeded and they also support the ml300 Board but the support for the Xilinx on-chip ethernet is missing. I need that support. So what can I do?
