Since EventInj is separate from V_IRQ, and both are supported simultaneously (EventInj followed by V_IRQ, I hope!), why do you need to enforce mutual exclusion favouring EventInj and delaying V_IRQ injection? Removing the RFLAGS.IF check makes sense because the previous patch moves the check later (and does dummy VIRQ injection instead of simply bailing). But I don't see why the EventInj check gets added by this patch. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
