💅 NE_ERR_NO_CP...VAIL_IN_POOL(9) — Kernel API Manual, section 9 ✨

okay bestie, so this whole page lives in the Kernel API Manual (that's the manual name, section 9, iykyk) — and the title got a lil truncated on the way in, but you already know what it is. Let's get into it 🫶

✨ NAME ✨

NE_ERR_NO_CPUS_AVAIL_IN_POOL — the error you get when the command to create an enclave is triggered and, like… there are literally no CPUs available in the pool. not one. zero. nada. 😭

🦋 SYNOPSIS 🦋

NE_ERR_NO_CPUS_AVAIL_IN_POOL

heads up bestie: this page is only the error definition itself — it doesn't describe a function signature or any options, so don't go looking for a big OPTIONS section. the description up top is the whole lore 💀

and that's the vibe check, bestie — go forth and read the rest of the NE lore 🌸

this iconic little page ships from ./include/uapi/linux in the Kernel API Manual, dated October 2026, and it answers to NE_ERR_NO_CP...VAIL_IN_POOL(9) — yes the title's still truncated, no she's not fixing it, it's part of her charm 💅✨
