Single Socket , Dual Core , No Hyperthreading CPU installed ->SCHED_MC

I upgraded my old laptop CPU from a AMD x64 turion to an AMD x64 X2 turion. I reconfigured my kernel with CONFIG_SMP and everything seems to work.

However, I cannot find more information about CONFIG_SCHED_MC. I don't need/want CONFIG_SCHED_SMT since /proc/cpuinfo indicates I don't have hyperthreading. (e.g. siblings = cpu cores).

Could anyone sched (hihi) some light on this? The Kconfig yields not much information. Google yielded only a Gentoo forum post indicating the difference between SMT and MC. Grepping through the kernel sources only shows CONFIG_SCHED_MC in /kernel/sched/core.c with very little information.

The only thing I found is a powersaving tunable, but that's it!

One paper seems to explain this in more detail here.

Is that all there is?
