💻 libnvme(9) — the enum that maps every controller register, bestie

okay so this is the <pink>libnvme</pink> API manual page, and today's main character is enum nvme_register_offsets — the controller registers for all transports. Like, this is the layout of BAR0/1 for PCIe, and the properties for fabrics. One enum to rule them all, no cap. 👑
