STRUCT SLOT_ADD_VCPU_REQ(9)

✨ struct slot_add_vcpu_req(9) ✨

okay so bestie, welcome to the struct slot_add_vcpu_req(9) page from the Kernel API Manual 💅 this one's short and sweet and honestly kind of iconic for it.

---

🎀 NAME 🎀

struct slot_add_vcpu_req — the SLOT_ADD_VCPU request, no cap 🫶 it's the little struct you hand over when you wanna add a vCPU to a slot.

---

🌸 SYNOPSIS 🌸

here's the whole vibe, literally the entire struct, look at her:

struct slot_add_vcpu_req {
    u64 slot_uid;
    u32 vcpu_id;
    u8 padding[4];
 };

that's it. that's the whole girl. ⭐

---

💖 Members 💖

• slot_uid — the slot's unique id 🦋 it maps to the slot you're adding the vCPU to, iykyk.
• vcpu_id — the vCPU ID of the CPU you're adding to the enclave 🔥 this is the actual one being added.
• padding — padding for the overall data structure 🙈 she's just here so the struct stays cute and aligned. main character energy in a supporting role.
