[Xen-devel] irq sharing in Xen

["sanjay kushwaha" <sanjay.kushwaha@xxxxxxxxx>]

Hi Folks,
Is IRQ sharing between domains supported in Xen?

I am trying to share a physical IRQ between dom0 and an HVM guest. but it is not working.


when the IRQ is owned only by dom0:
- I inject an irq into dom0 (send_guest_pirq)
- I get back an EOI in xen (__pirq_guest_eoi)

when the IRQ is shared between dom0 and hvm domain
- I inject an irq into dom0 (send_guest_pirq)
- I do not receive the EOI from dom0

Could someone please clarify on this?

Thanks,
Sanjay
