STRUCT IWL_RX_HANDLERS(9)

💅 struct iwl_rx_handlers(9) — Kernel API Manual, but make it a vibe 🦋

okay so bestie, welcome to the struct iwl_rx_handlers(9) page 💖 this is the Kernel API Manual, and today we're learning about the literal handler for FW notification. it's giving "small struct, big responsibilities" and honestly? iconic. no cap, it's just a few fields, so we'll be in and out in like two minutes ✨

🌸 NAME 🌸

struct iwl_rx_handlers — handler for FW notification 🎀

like, that's literally the whole personality. it handles FW notifications. periodt.

---

✨ SYNOPSIS ✨

here's the whole shape of it, character for character, don't come for me:

struct iwl_rx_handlers {
    u16 cmd_id, min_size;
    enum iwl_rx_handler_context context;
    void (*fn)(struct iwl_mvm *mvm, struct iwl_rx_cmd_buffer *rxb);
 };

so yes, two u16s stacked on one line, a context that's an enum iwl_rx_handler_context, and a function pointer fn that takes a struct iwl_mvm *mvm and a struct iwl_rx_cmd_buffer *rxb. and it returns void, because we're not about that return-value life here 💅

👑 MEMBERS 👑

every field, every single one, no skipping, we're not that kind of girl:

• cmd_id — command id 🆔 that's it, that's the whole thing. it's the id of the command.
• min_size — minimum size to expect for the notification 🍓 lowkey important: this is the smallest size you should expect for that notification. don't come crying if it's smaller.
• context — see iwl_rx_handler_context 🌈 it points you at the enum, so go read iwl_rx_handler_context(9) if you want the full lore.
• fn — the function is called when notification is received 📞🔥 this is your callback, main character energy — it gets invoked the moment the notification lands. signature is the one from the synopsis: (struct iwl_mvm *mvm, struct iwl_rx_cmd_buffer *rxb), returns void.

🫶 tiny vibe check: fn fires when the notification is received — that's what the manpage says, and I'm not about to invent extra behaviour on top of it, bestie. iykyk.

🦋 SEE ALSO 🦋

go touch grass in these files, they're all linked:

• Kernel file ./drivers/net/wireless/intel/iwlwifi/mvm/ops.c — the source of truth, go read it, it ate 💀
• enum iwl_rx_handler_context(9) — the enum behind the context field 💜

okay bestie that's the whole page, you ate that ngl 🌟 and for the sign-off, since you gotta know the receipts: this cutie came from ./drivers/net/wireless/intel/i... and it's dated October 2026 🎀 slay, bye 🧚💖
