💅 mei_cl_irq_read_msg — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of mei_cl_irq_read_msg(9)</p> — yes that's the one from the Kernel API Manual, and yes she's iconic. this is the function that handles a client message coming in off the irq path, and honestly? she eats. let's get into it 🎀

---

✨ NAME ✨

mei_cl_irq_read_msg — process client message 💌

like, that's literally her whole job. incoming client message → processed. periodt.

---

🦋 SYNOPSIS 🦋

int mei_cl_irq_read_msg (struct mei_cl *cl , struct mei_msg_hdr *mei_hdr
, struct mei_ext_meta_hdr *meta , struct list_head *cmpl_list );

four arguments, one int return, no cap. copy it exactly if you're writing it out, bestie, don't be creative with it 🙈

---

🌸 ARGUMENTS 🌸

• cl — the reading client 👑 she's the one doing the reading, main character energy fr
• mei_hdr — header of mei client message 📨 the little label on the package, yk?
• meta — extend meta header 🧚 the extra metadata situation, the extended one
• cmpl_list — completion list ✅ the list where completions go to hang out

---

⭐ RETURN ⭐

always 0. that's it. that's the whole vibe check — she does not miss, she does not fail, she returns 0, every time, no notes 💀🔥

ngl a function that always returns 0 is lowkey the most unbothered icon in the whole kernel. she said "i have no bad days" and meant it 🫶
