[Verse 1] When your kernel starts to crash and die And user-space just can't get by There's a way to look inside the core GDB will open up the door Set up your target system right Serial cable, debug light The kernel waits for you to say Put breakpoints in the right way [Chorus] Step and look, break and hook GDB is like a book Kernel data comes to life In the debugger's magic sight Step and look, break and hook Live debugging by the book When the system's going mad Debug kernel, make it glad [Verse 2] Build your kernel with debug on KGDB ready, symbols strong Magic SysRq breaks you in Or kernel panic lets you begin Connect your host with GDB Target remote, now you see The kernel stops and waits for you To walk the code pathways through [Chorus] Step and look, break and hook GDB is like a book Kernel data comes to life In the debugger's magic sight Step and look, break and hook Live debugging by the book When the system's going mad Debug kernel, make it glad [Bridge] Print the registers, check memory too Stack traces show what kernels do Step by step through every call Watch the code flow through it all Breakpoints set on vital lines Conditional breaks save you time Keep on running or single step The kernel secrets you will reap [Verse 3] Driver problems got you down Device errors all around Set your breakpoint in the flow Watch the data as it goes Interrupt code needs special care Tricky context, be aware But with patience you can see Find the bug and set it free [Final Chorus] Step and look, break and hook GDB is like a book Kernel data comes to life In the debugger's magic sight Step and look, break and hook Live debugging by the book Now the system's in control Debugging makes the kernel whole [Outro] From boot crash to runtime freeze GDB puts your mind at ease Deep debugging, kernel wide The system secrets are your guide
