Linux Kernel Compilation Nears 10-Second Barrier via Kbuild & AI Optimizations

New Kbuild patches and AI-driven compiler optimizations have cut Linux kernel defconfig build times to ~15 seconds on a 128-core AMD EPYC server — a ~30% gain without RAM disks — while allmodconfig builds approach two minutes; future Zen 6 and PCIe 6.0 hardware could push standard builds under 10 seconds.
