Kevin, Matt --
I started to look at these changes but I am not as familiar
with this code as you and, since multiple domains is just
now working again, I am hesitant to mess with it. Could
one or both of you provide a patch to fix up ia64 to
match Keir's interface change?
This is relatively URGENT as I believe this is the only
fix still needed to get ia64 multiple domains working in
the xen-unstable tree. (Hopefully, no recent or near-future
changes in xen-unstable will break it before we are able
to merge again.) Once we have it working in xen-unstable,
it will be much easier to find problems if something breaks.
And it is very likely that the Xen 3.0 freeze is coming soon
and it would be nice to have it in-tree before the freeze.
You may want to clone the xen-unstable tree as a base and
apply Kevin's recent patch (see xen-ia64-unstable cset 7664).
This should work unless another recent xen-unstable cset
has broken us again, which we would like to know now rather
than later anyway.
It appears we need to implement bind_virq_to_irqhandler
and unbind_from_irqhandler. I think bind_ipi_to_irqhandler is
probably just a panic stub for now until we have SMP guest
support.
Thanks,
Dan
