[Fedora-xen] [PATCH] enable xen-ia64 in fedora kernel cvs
This patch enables xen-ia64 support in the fedora kernel. It applies
to the cvs tree checked out according to the instructions at
http://people.redhat.com/davej/
At this point I''m requesting this patch be applied. Until the
hypervisor is updated to match the generic linux-2.6-xen.patch, it
won''t actually boot xen on ia64, but IMHO the changes are clean and
there''s no reason to believe they won''t work when %includexen
and
%buildxen are re-enabled. (It has already been demonstrated
previously on this list that the patches work in general and that
fedora-xen-ia64 builds, boots and runs ;-)
Breakdown of the changes:
- Add $(CFG)-ia64-xen.config target to devel/Makefile.config
- Add devel/configs/config-xen-ia64 override snippet
- Add xen_flags, xen_target and xen_image to spec-file to genericize
building of the hypervisor
- Add two symlinks that are specific to building on ia64. These
symlinks aren''t required in xen-ia64-unstable upstream, so include
shell conditionals to announce when they should be retired from the
spec file
Caveats:
- As described earlier, we need Juan to start matching the hypervisor
tarball to the xen-unstable changeset associated with
linux-2.6-xen.patch. It breaks boot on ia64 presently, but could
affect any architecture, so this is an important change in general.
- As of 2.6.17, configs/config-ia64-generic needs CONFIG_PNPACPI=y to
boot on systems without a graphics head. This is not related to xen
so I didn''t include it in this patch. I''ll be sending a
separate
patch for this issue, cc''ing fedora-ia64
