If i want to enable SMP, cores should be of same version( ex: both core should ARM 7 ) or we could enable SMP on different version.
There's kernel support for the bigLITTLE architecture in some ARM chips, but since it depends on being able to migrate execution streams between them, the various processors really *do* need to be compatible. You *really* don't want to try to make things work when some cores are ARM6 and some are ARM7, for instance - that way lies madness if you ever reschedule onto a different processor (and I'm not even sure our toolchains are able to generate a mixed-architecture binary without complaint). -------------- next part -------------- A non-text attachment was scrubbed...
