STRUCT LIBIE_CTLQ_DESC(9)

💅 struct libie_ctlq_desc(9) — Kernel API Manual 🎀

okay so bestie, we're diving into struct libie_ctlq_desc — yes it's a 9th-section kernel API manpage, yes it's giving "I live in ./include/linux/net/intel/libie/controlq.h" energy, and yes we're gonna read it together 💖

---

✨ NAME ✨

struct libie_ctlq_desc — the control queue descriptor format, aka the literal layout of one descriptor on the control queue. that's it. that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

struct libie_ctlq_desc {
    __le64 qword0;
    __le64 qword1;
    __le64 qword2;
    __le64 qword3;
 };

four little __le64 besties, all in a row. so clean. so iconic. four qwords and nothing else 👑

---

💜 Members 💜

• qword0 — flags, message opcode, data length etc — the "what is this and how big is it" qword, lowkey the main character of the descriptor ✨
• qword1 — virtchnl opcode, descriptor type and return value — the "what are we actually asking for, and hey here's the answer back" qword 🫶
• qword2 — indirect message parameters — the details you need when the message is being passed indirectly, iykyk
• qword3 — indirect message buffer address — and where that indirect buffer actually lives 🎀

ngl the manpage literally writes "etc" for qword0 and we are NOT elaborating further, because the original does not elaborate further. we respect the source. periodt 💀
