Thanks Konrad. The reason I am asking is if it is feasible and doable in a reasonable amount of time(2 ~ 3 weeks of development/testing) I can check with my boss if I could volunteer to do this work. I am not familiar with 2.6.27 code either but thought I could learn along with this.

Thanks

I've haven't looked at the 2.6.27 source (don't have the time).
The back-port might be as easy as just plucking in two or three
lines of code that pass in the
BIND_PIRQ__WILL_SHARE flag to the EVTCHNOP_bind_pirq hypercall.

But .. it might be much more complex where you will need to backport the
drivers/xen/events.c framework.

Yes. It should work.
