If so, you should approach that port directly and ask for advice (since it will differ greatly from one architecture to another). Is it a new processor that we don't currently have support for in the kernel tree? That's a much larger undertaking, normally a multi-year project First, you're going to need a toolchain that targets your CPU -- GCC, binutils and so on. Then you can start porting Linux. It's probably best to start by copying an existing architecture and modify it piecemeal. I can't really be more specific since your question is so vague. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
