Slective IRQ trapping.

Dear experts,


Does Xen-ARM support selective IRQ trapping i.e. configure some devices IRQ to trap to hypervisor while the rest to be directly handled in the guest. Does ARM virtualization extensions support such a use-case?

Thank you so much.

Thanks Ian. 

I have already taken a look at Asking Developer Questions (upon registration) and have  reread after you  email . But I can not see what's the issue?  is that my question not not understandable or ...? 


Thank you so much and best regards.

You've posted a several questions to the list over the last day with
little indication that you have considered many of the points on that
wiki page, e.g. reading the (hardware) docs, using tools to search the
source code, doing web searches etc. You've not given any background to
what you are trying to actual do as recommended. You haven't followed
the nettiquette guide.

Ok. No HTML emails and stopping top posting would make a good start, I
guess. :-)
