[Xen-ia64-devel] how to get the latest ia64 bits

[Aron Griffis <aron@xxxxxx>]

Hi Juan,

There are some significant fixes in xen-ia64-unstable.hg right now,
especially the xencomm patches.  All of the patches are ia64-only.
Since it's unlikely that Keir will pull xen-ia64 again prior to 3.0.3
release, how would you like to handle getting these fixes into your
tree?

I've done it two different ways so far:

1. Clone xen-3.0.3-testing, clone xen-ia64-unstable.  Pull
   xen-ia64-unstable into xen-3.0.3-testing, hg merge, then use
   pull-xen-unstable as normal.  The problem with this is that your
   changeset id will reflect the extra changesets pulled in from
   ia64-land.

        OR

2. Start with the same clones.  Create two patches and apply them in
   the spec-file.

Since method #1 is obvious and simple, I documented method #2 below.
Here are the steps I used to generate the patches attached to this
mail:

# 1. Clone upstream repos and create temporary trees

    hg clone http://xenbits.xensource.com/ext/xen-ia64-unstable.hg
    hg clone http://xenbits.xensource.com/xen-3.0.3-testing.hg
    hg clone http://free.linux.hp.com/~agriffis/pull-xen-unstable.hg
    hg clone http://hg.et.redhat.com/kernel/linux-2.6-xen-fedora
    cp -al xen-3.0.3-testing.hg xen-3.0.3-testing.hg+ia64
    cp -al linux-2.6-xen-fedora linux-2.6-xen-fedora+ia64

# 2. Remember tip changesets

    ia64_cset=$(hg -R xen-ia64-unstable.hg parents | \
        awk -F'[ :]' '/^changeset:/{print $(NF-1);exit}')

    testing_cset=$(hg -R xen-3.0.3-testing.hg parents | \
        awk -F'[ :]' '/^changeset:/{print $(NF-1);exit}')

# 3. Merge ia64 into testing

    cd xen-3.0.3-testing.hg+ia64
    hg pull ../xen-ia64-unstable.hg
    hg merge
    hg ci -m "merge xen-ia64-unstable.hg"
    cd ..

# 4. Generate hypervisor patch

    hg -R xen-3.0.3-testing.hg+ia64 di -r $testing_cset -r tip | \
        filterdiff -p1 -i 'xen/*' --strip=1 > ../xen-ia64-$ia64_cset.patch

# 5. Generate linux patch

    cd linux-2.6-xen-fedora+ia64
    hg -R ../xen-3.0.3-testing.hg+ia64 di -r $testing_cset -r tip | \
        ../pull-xen-unstable.hg/pull-xen-unstable --filter | \
        patch -p1
    hg add
    hg remove --after
    hg ci -m "update to xen-ia64-unstable-$ia64_cset"
    hg export tip > ../linux-2.6-xen-ia64-$ia64_cset.patch

Which method do you prefer?

Thanks,
Aron
