STRUCT ENCLAVE_START_REQ(9)

💖 struct enclave_start_req(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual — it's all about struct enclave_start_req, and ngl it's giving "the little form you fill out to wake an enclave up" energy. 🫶

---

✨ NAME ✨

struct enclave_start_req — the ENCLAVE_START request. periodt, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

here's the actual shape of it, copy it exactly bestie:

struct enclave_start_req {
    u64 slot_uid;
    u64 enclave_cid;
    u64 flags;
 };

three fields, all u64, no cap. 💅

---

🦋 Members 🦋

• slot_uid — the slot's unique id, mapped to the enclave you're starting. literally the "which one" field. 🔥
• enclave_cid — the Context ID (CID) for the enclave's vsock device. and here's the cute part: if it's 0, the CID gets autogenerated for you. no thoughts, it just happens. ✨
• flags — the flags the enclave starts with (e.g. debug mode). yes bestie, debug mode is a flag, go off. 🐛
