[Cyrill Gorcunov - Wed, Sep 16, 2009 at 12:58:35PM +0400] ... | | Hi Sheng, | | is there was some problem with it? I'm asking you | because if disable_apic=1 then any apic write/read | operations become NOPs. So I don't see how it may | hurt. But I could be missing something. | | -- Cyrill Ah, I see -- it's due to your other patch... Hmm this makes all "disable apic" idea less general. And safety of ack_APIC_irq is now under suspicious. -- Cyrill _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
