[Xen-devel] Re: [patch]Add a new reboot method
Is it really a good idea to go poking an arbitrary I/O port without some kind of probing for its purpose? Do we even care about having a more efficient reboot method when the current methods are surely all sub-second already?

Hi, Keir,
New chipsets support a new reboot method by writing port 0xcf9, sometimes this is more efficient than “keyboard controller reboot” and “triple fault reboot”. This patch add this new method and use it as a preferable one.
