iio_simple_dummy_trigger_h(9)

✨ iio_simple_dummy_trigger_h(9) — the kernel API manual, but make it make sense ✨

okay so bestie, welcome to the iio_simple_dummy_trigger_h page from the Kernel API Manual 💅 this one's short and sweet and honestly kind of the main character of the buffered capture saga 🎀

---

🌸 NAME 🌸

iio_simple_dummy_trigger_h — literally the trigger handler function 💖 that's it, that's the whole name, no cap.

---

🦋 SYNOPSIS 🦋

irqreturn_t iio_simple_dummy_trigger_h (int irq , void *p );

copy it exactly like that, she's precise 👑

---

💜 ARGUMENTS 💜

• irq — the interrupt number 🔥 that's the whole vibe of this one, it's just the irq number, periodt.
• p — private data 🫶 and ngl it's always a pointer to the poll func. always. like clockwork.

---

🧚 DESCRIPTION 🧚

so this is the guts of buffered capture 😭 the actual inner workings, the whole reason we're here.

when a trigger event goes down, if the pollfunc is attached, this handler gets called as a threaded interrupt — which, important detail bestie, means it may sleep 💀 so don't be out here assuming it's all fast and non-blocking, iykyk.

its whole job? grabbing data from the device and pushing it into the associated buffer 🌈 that's the assignment, and it ate 🔥

⭐ SEE ALSO ⭐

• Kernel file ./drivers/iio/dummy/iio_simple_dummy_buffer.c — go read it, slay 📖
• iio_simple_dummy_unconfigure_buffer(9) — the cleanup counterpart, iconic 👑

---

🎀 reminder: threaded interrupt = may sleep. do not forget, bestie, this is not a drill 🫶

alright that's the whole page 🌸 it lives in ./drivers/iio/dummy, dated October 2026, and it's the iio_simple_dummy_trigger_h(9) entry from the Kernel API Manual — mwah, go forth and buffer 💖✨
