STRUCT SLOT_ADD_MEM_REQ(9)

🌸 struct slot_add_mem_req(9) 🌸

okay so bestie, welcome to the Kernel API Manual — yes, the actual manual name, we're being official today 💅 — and today's main character is struct slot_add_mem_req. It's giving "small struct, big job" energy, ngl.

---

✨ NAME ✨

struct slot_add_mem_req — the SLOT_ADD_MEM request. that's it, that's the whole name, periodt. 🎀

---

🦋 SYNOPSIS 🦋

here's the whole vibe, literally copy-pasted from the source of truth so you can't mess it up:

struct slot_add_mem_req {
    u64 slot_uid;
    u64 paddr;
    u64 size;
 };

three little u64s, all in a row, iconic behavior honestly 🔥

💖 Members 💖

let's meet the cast, one by one 🫶

• slot_uid — the slot's unique id, mapped to the slot you're adding that memory region to. it's the "which slot tho" field, iykyk.
• paddr — the physical address of the memory region you're adding to the slot. not virtual, not vibes — physical 💀
• size — the memory size, in bytes, of the memory region going into the slot. bytes, bestie, always bytes.

nerd note: this whole page lives under ./drivers/virt/nitro_enclaves, and it's dated October 2026. yes, the future. we're early. 🧚

and that's the page, bestie — go add that memory, slay, and remember: slot_uid, paddr, size, in that order. mwah 💋✨
