[Verse 1] Starting with a bloated kernel, features everywhere Drivers for devices that your system doesn't care Embedded boards are crying out for memory to spare Time to strip it down and build with surgical repair Network stacks and filesystems eating precious RAM Graphics drivers for displays you'll never need or plan Every module adds weight to your system's diagram Lean and mean's the goal, cut fat where you can [Chorus] Strip it, trim it, make it lean Build the smallest kernel scene Target architecture's king Memory footprint's everything Strip it, trim it, optimize For the hardware that you prize Less is more when space is tight Kernel tuning done just right [Verse 2] Configuration menus hold the keys to what you need Turn off CONFIG options that your target won't feed Wireless when you're wired is unnecessary greed Power management features that embedded doesn't heed Cross compiler ready for your ARM or RISC-V core Architecture flags will open up performance door Cache line sizes matter more than they did before Instruction sets aligned with what your chip has in store [Chorus] Strip it, trim it, make it lean Build the smallest kernel scene Target architecture's king Memory footprint's everything Strip it, trim it, optimize For the hardware that you prize Less is more when space is tight Kernel tuning done just right [Bridge] Make modules static when you know what stays Dynamic loading costs in embedded days Compression algorithms squeeze the final size LZO or LZMA, choose your compromise Debug symbols out when production's here Printk statements that nobody will hear Every kilobyte matters in this space Optimization puts performance in its place [Verse 3] Defconfig files guide your custom build Architecture defaults but your needs aren't filled Start with minimal config, add what must be willed Balance functionality with memory bill Boot time matters when your system starts Faster init, fewer moving parts Kernel command line, fine-tune the arts Of embedded excellence that sets you apart [Chorus] Strip it, trim it, make it lean Build the smallest kernel scene Target architecture's king Memory footprint's everything Strip it, trim it, optimize For the hardware that you prize Less is more when space is tight Kernel tuning done just right [Outro] From bloated beast to streamlined machine Your kernel build is tight and clean Embedded systems running free Optimized for efficiency
