[Xen-devel] spinning during suspend

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I'm still working on the suspend code for windows under GPLPV, and am
having problems with SMP.

What is the best way to get the other CPU's spinning? What I'm doing is
cranking the IRQL right up to the highest level (eg disabling
interrupts) and then just making repeated calls to SCHEDOP_yield, but
that is really chewing through CPU and slowing everything down to a
crawl.

Any suggestions?

Thanks

James
