STRUCT LIBIE_CTLQ_XN_RECV_PARAMS(9)

💖 NAME 💖

struct libie_ctlq_xn_recv_params — the little request struct that says "hey, go receive some xn responses for me" 🫶

ok so real talk, this page lives in the Kernel API Manual (yes, struct libie..._recv_params(9), that's the one, bestie ✨), and it's basically the starter pack for pulling xn responses off a control queue.

✨ SYNOPSIS ✨

struct libie_ctlq_xn_recv_params {
    void (*ctlq_msg_handler)(struct libie_ctlq_ctx *ctx, struct
libie_ctlq_msg *msg);
    struct libie_ctlq_xn_manager            *xnm;
    struct libie_ctlq_info                  *ctlq;
    u32 budget;
 };

like, that's the whole thing. four members. no cap. 💅

🎀 Members 🎀

okay so let's meet the squad, one by one 👑

• ctlq_msg_handler — your handler for Rx messages that have no matching xn. this one is mandatory, so no ghosting it 🙈. signature's literally void (*ctlq_msg_handler)(struct libie_ctlq_ctx *ctx, struct libie_ctlq_msg *msg) — that's the whole vibe.
• xnm — the Xn manager, aka the one whose whole job is processing Xn entries. main character energy fr 🌟
• ctlq — control queue information. yes it's just the info, it's giving "who am I, where do I belong" 🦋
• budget — a u32, and it's the maximum number of messages to process. think of it as your screen-time limit but for message processing 💀

lowkey obsessed with how tidy this is. go read the whole controlq.h friend group, iykyk 🧚

and that's the page!! tysm for reading bestie, this one's from ./include/linux/net/intel/libie, dated October 2026, and it goes by struct libie..._recv_params(9). periodt. 💜🌸
