Subject: [Openmosix-devel] [HOWTO] oM kernel port to xen

Hi,

Here's a quick howto to have a oM domU kernel on latest xen (2.6.15).
it's not totally automatic, but it does 99% of the job.

you need to have the following program: patchtool [1], svn and mercurial.

[1] http://tab.snarc.org/download/patchtool/patchtool-0.7.tar.bz2

===============================

hg clone http://xenbits.xensource.com/linux-2.6-xen.hg
svn co svn://openmosix.snarc.org/om/kernel-2.6/trunk linux-2.6-om wget
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.15.tar.bz2

tar xvjf linux-2.6.15.tar.bz2

cd linux-2.6-om
sh ./scripts/unsparse diff ../linux-2.6.15 ../linux-2.6-xen.hg

cd ../linux-2.6-xen.hg

hg diff > patch-om

for f in `patchtool list patch-om | sed -e 's;^b/;;'` do
        dir=`dirname $f`
        fname=`basename $f`

        xname=`echo $fname | sed -e 's/\.\([a-zA-Z]*\)$/-xen.\1/'`
        file="$dir/$fname"
        xfile="$dir/$xname"

        if [ "$xfile" == "$file" ]; then
                continue
        fi
        if [ -f $xfile ]; then
                echo "patching $xfile .."
                patchtool get patch-om $f > dopatch
                patchtool modify dopatch --move '.S' '-xen.S' --move '.c'
'-xen.c' | patch -p1
                rm dopatch
        fi
done

==================================

now you need to fixup the few files that patch fail to do.
"find -name '*.rej'" will give you the list of files.

Cheers,
