STRUCT LIBIE_CTLQ_CTX(9)

💅 struct libie_ctlq_ctx(9) — Kernel API Manual, bestie edition 🎀

Okay so listen — this is the manual page for struct libie_ctlq_ctx(9), from the Kernel API Manual, and it's literally the little home base where your control queue info and your MMIO region info live together. One struct, two vibes. Let's get into it ✨

---

🌸 NAME 🌸

struct libie_ctlq_ctx — contains controlq info and MMIO region info

No cap, that's the whole personality: it holds the controlq info, and it holds the MMIO region info. Iconic, minimal, does exactly what it says 🫶

---

✨ SYNOPSIS ✨

Here's the whole thing, exactly as it's declared:

struct libie_ctlq_ctx {
    struct libie_mmio_info  mmio_info;
    struct list_head        ctlqs;
    spinlock_t ctlqs_lock;
 };

Three members, zero notes of drama. Keep scrolling for the member-by-member breakdown 💖

---

💖 Members 💖

• mmio_info — the MMIO region info structure 💫 That's your window into the memory-mapped I/O situation.
• ctlqs — the list that stores all the control queues. Every single one of them lives in this list, bestie 👑
• ctlqs_lock — the lock for the control queue list 🔒 So like, the list is protected, we respect the lock, no one touches ctlqs without it. Periodt.

🦋 SEE ALSO 🦋

First off, the source of truth lives in the kernel file ./include/linux/net/intel/libie/controlq.h, and there's an enum hanging out there too (iykyk) 👀

Then the whole friend group, in case you wanna go down the rabbit hole:

• enum libie_ctlq_type(9)
• struct libie_ctlq_reg(9)
• struct libie_cp_dma_mem(9)
• struct libie_ctlq_msg(9)
• struct libie_ctlq_create_info(9)

• libie_cp_can_send_onstack(9)
• struct libie_ctlq_xn_recv_params(9)

Like, go read all of them, they're all main characters in this saga 🌈
