I'm configuring the Linux kernel and at this point I am not sure what it means.
Symmetric multi-processing support
This enables support for systems with more than one CPU. If you have a system with only one CPU, say N. If you have a system with more than one CPU, say Y.
If you say N here, the kernel will run on uni- and multiprocessor machines, but will use only one CPU of a multiprocessor machine. If you say Y here, the kernel will run on many, but not all, uniprocessor machines. On a uniprocessor machine, the kernel will run faster if you say N here.
What douse this means "more than one CPU" ?
I have a Muticore CPU with eight processor cores. does this apply to my CPU or only to two processors on the motherboard, regardless of processor cores?
Are the processor cores meant or processor chips?
I would say that this function applies to systems like this. Regardless of the processor cores, only the processor units (chips) count.
