NITRO ENCLAVES (NE) KERNEL DRIVER INTERFACE(9)

💅 Nitro Enclaves (NE) Kernel Driver Interface

okay so real talk, bestie — this one lives in the Kernel API Manual, section (9), and it's the glow-up page for the Nitro Enclaves (NE) kernel driver interface. She's not here to give you a whole essay, she's here to hand you the friend group. Think of it as the group chat roster: every single page you're gonna need to actually make enclaves happen, listed so you never have to ask "wait who do I talk to about this" ever again. iykyk ✨
