eeh_event_handler(9)

💅 eeh_event_handler(9) — a Kernel API Manual moment 🎀

ok so first things first, bestie: this page lives in the Kernel API Manual, section 9, and the star of the show is eeh_event_handler. yes it's a whole vibe, and yes we're gonna get into it 💖

---

✨ NAME ✨

eeh_event_handler — Dispatch EEH events. also @dummy — unused. that's it, that's the tweet 🫶

---

🌸 SYNOPSIS 🌸

int eeh_event_handler (void * dummy );

literally one function, one pointer, no cap ✨

---

🦋 ARGUMENTS 🦋

• dummy — -- undescribed -- 😭 the manpage literally does not describe it. it's giving mysterious. it's giving main character who refuses to elaborate. and honestly? iconic 💅 (also it's unused, per the NAME section, so like... don't stress about it)

---

👑 DESCRIPTION 👑

ok so here's the situation, and it's lowkey a whole thing: the detection of a frozen slot can occur inside an interrupt, where it can be hard to do anything about it. like, imagine trying to have a full conversation in the middle of a group chat spam storm — that's the interrupt context. not the moment, fr fr 😭

so the goal of this routine is twofold and both parts ate:

1. pull these detection events out of the context of the interrupt handler — get them out of the chaos 🌪️
2. re-dispatch them for processing at a later time in a normal context — let them cook somewhere calm, at a time that actually makes sense 🍓

the way that this is literally just "defer it to a sane moment" is so real. no drama, just scheduling ✨
