bq257xx_irq_handler_thread(9)

💖 bq257xx_irq_handler_thread(9) — the charger-interrupt handler bestie 💖

okay so this one lives in the Kernel API Manual, section 9, and it's literally all about handling charger interrupts. it's giving "backstage pass to the power supply subsystem" energy and honestly? iconic. 🎀

---

✨ NAME ✨

bq257xx_irq_handler_thread — handle charger interrupt 🫶

---

✨ SYNOPSIS ✨

irqreturn_t bq257xx_irq_handler_thread (int irq , void *private );

---

✨ ARGUMENTS ✨

• irq — the interrupt number. that's it, that's the number of the interrupt, no cap 💅
• private — a pointer to the driver's private data. bestie, this is where the driver keeps its stuff 🔥

---

✨ DESCRIPTION ✨

so this is the thread handler for charger interrupts. it's the one that actually does the follow-up work once a charger event comes knocking ✨

when it runs, it triggers a re-evaluation of the external power status, and it updates the power supply state in response to charger events. so like, charger does a thing → this handler notices → power state gets refreshed. main character energy, truly 👑

---

✨ RETURN ✨

returns IRQ_HANDLED if the interrupt was processed. that's the vibe check passing 🌈
