fman_unregister_intr(9)

💅 fman_unregister_intr(9) — Kernel API Manual 🎀

okay so bestie, we're in the Kernel API Manual today and this one is literally about fman_unregister_intr — yes that's the whole function name, she's long, she's iconic, she ate. ✨

---

🌸 NAME 🌸

fman_unregister_intr —

and that's it. that's the description. blank. empty. the void. she said "my name is enough" and honestly? main character energy. 🫶

---

🦋 SYNOPSIS 🦋

void fman_unregister_intr (struct fman *fman , enum fman_event_modules
module , u8 mod_id , enum fman_intr_type intr_type );

look at her. returns void, takes four things, no notes. periodt. 💅

---

✨ ARGUMENTS ✨

• fman — a pointer to the FMan device. like, the actual device. pls don't hand her a random pointer, bestie 😭
• module — the calling module. which module is calling? it's you. you're the module. 🪞
• mod_id — the module id — and if there's more than 1 of them, use it; if not, '0'. that's the rule, no cap.
• intr_type — interrupt type (error/normal) selection. so you gotta pick a lane: error, or normal. choose wisely 💀

---

💖 DESCRIPTION 💖

so what does she do? she's used to unregister an event handler to be processed by FMan. that's the whole vibe — handler goes in, handler comes out, FMan stops processing it. lowkey satisfying ngl. 🌈

---

⭐ RETURN ⭐

0 on success; error code otherwise. 🎀

okay tiny heads-up bestie: the synopsis up there says void, and this section says 0 on success. both of those are literally what the page says, so i'm just holding the receipts — iykyk 🙈

mwah 💋 that's the page — sourced from ./drivers/net/ethernet/freesca... (yeah she got cut off mid-word, she's mysterious like that 🧚) and dated October 2026, which is somehow both the future and also so last season. bye bestie, go unregister something responsibly 💜
