thc_interrupt_handler(9)

💅 thc_interrupt_handler(9) — like, the interrupt handler page, bestie

okay so real quick, this whole thing lives in the Kernel API Manual, section 9, and the page is literally called thc_interrupt_handler — say that three times fast, i dare you 🫶

---

✨ NAME ✨

thc_interrupt_handler — handles THC interrupts. that's it, that's the vibe 💫

---

🌸 SYNOPSIS 🌸

int thc_interrupt_handler (struct thc_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — the pointer of the THC private device context. yes bestie, it's a pointer, it's a struct thc_device, and it's giving main character energy 👑

---

🦋 DESCRIPTION 🦋

okay so THC interrupts are not one thing, they're like a whole friend group 💅 and there are several types:

• external touch device (TIC) non-DMA interrupts
• PIO completion interrupts
• DMA interrupts
• I2C subIP raw interrupts
• error interrupts

lowkey iconic lineup ngl 🌈

so what does this function actually do? it's a help function for interrupt processing 🔥 here's the rundown:

1. it detects the interrupt type
2. it clears the interrupt status bit
3. it returns the interrupt type back to the caller so they can do future processing

so it's basically the group-chat admin that reads the message, reacts, and hands you back the vibe check so you know what to deal with next 😭✨

---

⭐ RETURN ⭐

the combined flag for interrupt type. one flag, but like, combined — iykyk 💖
