Getting to Know the Linux Kernel: A Beginner's Guide
summary
Hands-on guide to grab the Upstream tree from kernel.org, edit configuration with make menuconfig, build with make -j (expect long compile times), and never remove a known-good kernel because a broken build can leave the system unbootable. Use testing tools like LTP (3–4 hrs) and kselftest (20–30 min), debug with ftrace, dump_stack, objdump+addr2line on vmlinux and GDB, and send small, well-documented patches via mailing lists to maintainers (use the kernel script to find them).
