Does the embedded linux kernel support all the CPU?

Hi,

First of all I am new to embedded Linux.
In the kernel Makefile,there is a long list of make targets for different microprocessors. My question is, does Linux kernel only support those CPUs, or I can implement embedded Linux on any CPU.

Thanks,
Dave Xu

A CPU (or in some cases the architecture) has to be supported if you want to run Linux on it. If it is not supported you have to port the kernel to it first.

Thanks TobiSGD for the response!
Could you elaborate a little on how to port the kernel for an originally unsupported CPU?

Thanks,

Sorry, I am not a kernel developer, but maybe this can help: http://free-electrons.com/docs/kernel-porting/

The manufacturer of the processor or board may be able to supply a Linux port. What processor are you working with?
