64bit + linux-3.8.13/rtai-4.0 + linuxcnc-2.6.0-pre

The kernel patch came from the links below..

Thread discussing the patch comments.gmane.org/gmane.linux.real-time.rtai/24950
Link to the patch cvs.gna.org/cvsweb/magma/base/arch/x86/patches/?cvsroot=rtai

Kernel config attached.

Regards.

Steve.

2nd attempt to attach the config file.

Try renaming it to config.txt

txt is about the only thing certain to work

I am obviously missing something.

All the patches are named x86 and not x86_64

Are you saying that the x86 patches work on x86_64?

If so, I have been assuming that no patches existed since 2.6.34, because of the name of them

regards

From the linked thread.

Starting with kernel 2.6.24, the sources for arch/x86_64 and arch/i386 have been unified into a single x86
directory. This is why the more recent patches can be found in base/arch/x86/patches. While the released
versions don't seem to include a 2.6.26 patch, you can get one from cvs:

Great, if you can attach your config as a txt file or in a zip, 2 ways guaranteed to work, I will try building it now

cheers

I edited my earlier post, its attached there.

Steve.

Some more things I should mention..

The config file is for a vanilla kernel from kernel.org

The linuxcnc sources will complain about sse math and version.h during the realtime modules build, my fixes are below.

version.h can be fixed with a simple symlink

Attached is a patch for the x86 kernel Makefile, this is probably entirely wrong, but it worked for me.

Steve.

Thanks, I could not build on my existing x86_64 partition easily as I have nvidia drivers installed and would have to keep switching configs.

Just finished installing on a new x86_64 partition.

Your kernel config is quite similar to one I used for 3.8.0, but with newest processor instruction set and a much reduced set of modules

I will see what shakes out

Are you using the RTAI 4.0 Tarball or something else?
