What is an appropriate application of the event channel if it is low bandwidth? Little bandwidth == one 'sticky bit' of information that is cleared by the receiver. It's an event pending bit. High performance == when you send an event, teh receiver will receive an upcall sometime later. The mechanisms involved are simple so the CPU overhead is dominated by context switch time, if a context switch is required. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
