zpa2326_handle_irq(9)

💅 zpa2326_handle_irq — like, the interrupt handler bestie

Okay so this is a page from the Kernel API Manual (yes, the (9) means it's a kernel function, iykyk) and it's all about zpa2326_handle_irq. Buckle up, it's short but it serves. ✨

---

✨ SYNOPSIS ✨

irqreturn_t zpa2326_handle_irq (int irq , void *data );

That's the whole vibe. Two args, one return type, no drama. 🎀

---

🌸 ARGUMENTS 🌸

• irq — the interrupt line the hardware uses to ping everyone that new data has arrived. It's literally the doorbell of the sensor. 🔔
• data — the IIO device that's associated with the sampling hardware. Think of it as the main character this interrupt belongs to. 👑

---

🦋 DESCRIPTION 🦋

So what does it actually do? Two things, and it does them in order:

1. Timestamp the buffered samples as soon as possible — like, the moment the data shows up, no waiting around, timestamps are due now. ⏱️
2. Then schedule the threaded bottom half. Like, "okay bestie, the fast part's done, the rest can go in the thread." 🧵

That's it. That's the function. Efficient queen behavior, honestly. 💅

💖 RETURN 💖

Always successful. No cap. It doesn't fail, it doesn't return an error — always successful, periodt. 🫶

Heads up bestie: the pressure driver's docs live under ./drivers/iio/pressure, so that's where you'll find this whole squad. 🌈

And that's the page! Signing off from the ./drivers/iio/pressure directory, dated October 2026 — stay timestamped, stay threaded, and don't forget to handle your interrupts. 🧚💜⭐
