✨ qcom_labibb_sc_isr ✨

okay bestie, so this is a page from the Kernel API Manual — section 9, the interrupt one — and the star of the show is qcom_labibb_sc_isr. say hi 👋

---

🌸 NAME 🌸

qcom_labibb_sc_isr — the interrupt routine for Short Circuit Protection. that's the whole vibe. it's the homie that picks up the phone when the hardware calls about a short 💅

---

🎀 SYNOPSIS 🎀

irqreturn_t qcom_labibb_sc_isr (int irq , void *chip );

literally just those two args, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• irq — the interrupt number. yes, the actual number, bestie, not a vibe 🔢
• chip — the main driver structure. the big one. the main character 👑

---

⭐ DESCRIPTION ⭐

so Short Circuit Protection (SCP, not to be confused with anything else, that's its acronym) does its little thing: it signals to the client driver that a regulation-out event has happened — and then it goes and schedules a recovery worker. that's the sequence. signal, then schedule. slay ✨

meanwhile! the LAB and IBB regulators get automatically disabled by the Portable Batch System (PBS) — like, not even asked, it just happens — and then the worker function enables them again if the hardware stops signaling the short circuit event. big "if" energy there, but that's the deal 💀

---

💜 RETURN 💜

• IRQ_HANDLED — for success 🎉
• IRQ_NONE — for failure 😭

that's it. two outcomes. icon behavior.
