STRUCT SGX_PAGEINFO(9)

✨ struct sgx_pageinfo(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct sgx_pageinfo — an enclave page descriptor 🎀 this is literally the little info packet that tells the kernel about one single SGX enclave page, and honestly? it's giving "small but crucial" and we're obsessed 💅

🌸 NAME 🌸

struct sgx_pageinfo — an enclave page descriptor ✨

---

🦋 SYNOPSIS 🦋

struct sgx_pageinfo {
    u64 addr;
    u64 contents;
    u64 metadata;
    u64 secs;
 };

no cap, that's the whole struct — four u64s and a dream 🫶

---

💖 Members 💖

• addr — the address of the enclave page 📍 like, where is this page at, bestie
• contents — a pointer to the page contents 🧚 this is the actual page data, the main character energy of the struct
• metadata — a pointer that goes either to a SECINFO or a PCMD instance 👀 yes, it's one of those "depends on the situation" pointers, iykyk
• secs — the address of the SECS page 👑 the SECS page is the enclave's whole vibe, so of course it gets its own field
