Is there any plan (or benefit) toadd more flexible priority policy, since by current way the priority isdecided completely by compilation sequence of different drivers?Sorry, I should say driver init sequence here. :-) If hardirq 'scheduling' is demonstrated to be an issue then we can certainly work on this. There are various possible solutions -- the easiest being to simply round-robin scan the event_pending array. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
