rsi_handle_interrupt(9)

💖 rsi_handle_interrupt(9) — the kernel API manual, but make it make sense 🎀

okay so bestie, we're in the Linux kernel API manual (section 9, the "kernel internals" girlies), and today's main character is rsi_handle_interrupt. That's the function the kernel calls the moment an interrupt shows up. Like, the interrupt happens, and this function is literally the one picking up the phone. no cap. 🔥

---

✨ NAME ✨

rsi_handle_interrupt — this function is called upon the occurrence of an interrupt.

That's it, that's the whole job description. It handles the interrupt. She's the handler. Periodt. 💅

---

🌸 SYNOPSIS 🌸

void rsi_handle_interrupt (struct sdio_func *function );

Yeah, returns nothing, takes one thing. Simple. Clean. Iconic.

---

🦋 ARGUMENTS 🦋

• function — a pointer to the struct sdio_func structure. Just a pointer to the sdio_func struct, that's all she needs. 🫶

---

💜 RETURN 💜

None.

Like, literally none. It's void. She gives nothing back and honestly? relatable. She does the work and leaves. no notes. ✨

🌈 SEE ALSO 🌈

Okay this is where the friend group shows up, because she does not operate alone, bestie. The kernel file she lives in:
