I need a Linux kernel compiled with debug features for a kernel module development.What all debugging configuration options should I include for kernel compilation,So that I can avail to all available debug tools.
Also, I am thinking about including all available debug facilities in kernel, like including whole of the "Kernel Hacking" configuration branch into the kernel.Will there's any side effect to it, in terms of: final build size and performance penalty etc.
Of course there are side effects in terms of build size and performance. However, you are doing a debug build! They aren't huge and some can be modules that you only load when you're using them, but still you aren't going to be using it for your high performance production server.
Beyond that there doesn't seem to be anything to answer in your question. If you know what tools you want to avail yourself of, it should be clear which options to enable to get the tools to work. If you are asking about what software to use to debug the kernel, that's a different question, and you should figure out exactly what you want to ask and ask that question.
