RE: [Xen-ia64-devel] [Patch] build pacth for acpi
Kevin is correct, it is a result of all of the file movement
that is necessary because Xen/x86 changes many files in
linux-sparse that do not need to be changed for Xen/ia64.
One of these is acpi/tables.c.
What I do is use two hg trees. One is the master tree. Never
build xenlinux in the master tree. The other is the build tree
and is cloned from the master tree. Never pull into the build tree,
just re-clone it if you need to get updates.
So:
# get master tree
cd $my_xen_dir
hg clone http://xenbits.xensource.com/ext/xen-ia64-unstable.hg
# to build
cd $my_xen_dir
hg clone xen-ia64-unstable.hg build.hg
cd build.hg
make
# to update to newer bits
cd $my_xen_dir/xen-ia64-unstable.hg
hg pull
# to build newer bits, remove tree and re-clone
cd $my_xen_dir
rm -fr build.hg
hg clone xen-ia64-unstable.hg build.hg
cd build.hg
make
# to do xen (not xenlinux) development
cd $my_xen_dir
hg clone xen-ia64-unstable.hg new_feature.hg
cd new_feature.hg/xen
## change xen files and make in xen directory
## but don't run make in new_feature.hg!
hg commit # commit xen changes
cd $my_xen_dir/new_feature.hg
hg push ../xen-ia64-unstable.hg
# to do xenlinux development (complicated)
cd $my_xen_dir
hg clone xen-ia64-unstable.hg new_feature.hg
cd new_feature.hg
## change xenlinux files. DON'T BUILD YET
## first record your changes because once you build,
## "hg diff" is confused by all the moved files
hg diff > ~/patches/my_xenlinux_feature.patch
cd $my_xen_dir/new_feature.hg
make
## xenlinux feature testing
cd $my_xen_dir/xen-ia64-unstable.hg
patch -p1 < ~/patches/my_xenlinux_feature.patch
hg commit # clone won't get new changes without commit
## now re-test to ensure your patch works as expected
cd $my_xen_dir
hg clone xen-ia64-unstable.hg new_feature.hg
cd new_feature.hg
make

I hope that helps!
