[Verse 1] When the kernel crashes and your system goes dark Time to fire up KGDB and hunt for that spark Connect your debugger through the serial line Set your breakpoints where the code should align Step through the functions in the kernel space Watch variables change at a measured pace [Chorus] K-G-D-B for debugging deep Trace the calls that make systems weep Profile syscalls, watch them flow Hardware meets software, now you know Diagnose the issues, find the bug Kernel debugging gives your brain a hug [Verse 2] Kernel traces tell a story of execution flow Enable tracing points to watch the data grow Function graph tracer shows the call chain clear Event tracing reveals what happened here Parse the timestamps, understand the sequence Every microsecond has its own significance [Chorus] K-G-D-B for debugging deep Trace the calls that make systems weep Profile syscalls, watch them flow Hardware meets software, now you know Diagnose the issues, find the bug Kernel debugging gives your brain a hug [Bridge] System calls bridge user space to kernel land Profile their performance, understand demand Latency spikes and bottlenecks appear When hardware drivers aren't crystal clear Integration issues hide in timing races Debug with patience through all the phases [Verse 3] Hardware registers tell their silent tale When device drivers start to fail Memory mappings and interrupt lines Check the handshake between designs DMA transfers and cache coherency Every layer needs its guarantee [Chorus] K-G-D-B for debugging deep Trace the calls that make systems weep Profile syscalls, watch them flow Hardware meets software, now you know Diagnose the issues, find the bug Kernel debugging gives your brain a hug [Outro] From silicon to software stack Debug forward, trace it back Master tools for system sight Make your kernels run just right
