It seems to me that all NIC interrutps should reach do_irq when desc->status & IRQ_GUESTis TRUE. Am I right ?Can it happen that ordinary interrupts of the NIC (interrupt 11 in this example)will reach do_IRQ() without this flag set ? No. Xen only handles timer and serial interrupts. All other I/O devices are handled by guests. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
