Hi everyone. I am just reading the kernel code, adding some code to make it pause and print some text and then interact with it a little bit. I have compile the kernel successfully and run the kernel in QEMU. It did work.Nice. But, when I reading the source, I found that there are just too many files there, which make it hard for me to manage. With so many files, It's hard to change directories, read and modified and still remember what you are doing (so many files with the same/similar name). I know that's because Linux support many architectures, and that 's the reason why there are so many folders under the 'arch' directory of the source code. So, I wonder, as I only want the source for x86 device, can I simply remove that source files which are unrelated to x86 and still make the kernel work as normal? I mean, can I just remove all the directory under 'arch' except 'x86-64' ? Also, are there any other files that I can safely removed and won't hurt the kernel ? Thanks in advance. (btw, I don't know whether this question is asked before. I google it but find nothing related. If it's duplicated, please give me some pointer to the mailing list where this topic located )
