xe_i2c_irq_handler(9)

💅 xe_i2c_irq_handler(9) — like, the full tea 🫖

okay bestie, welcome to the Kernel API Manual ✨ — this one's a lil function from the Xe i2c crew and it's honestly so straightforward it's giving main-character efficiency 🌈 keep reading, it's short and slay 💖

---

🌸 NAME 🌸

xe_i2c_irq_handler — literally the handler for I2C interrupts 💅 no cap, that's the whole job description

---

✨ SYNOPSIS ✨

void xe_i2c_irq_handler (struct xe_device *xe , u32 master_ctl );

that's it, that's the signature 👑 copy it exactly, don't get creative with it 🙈

---

🎀 ARGUMENTS 🎀

• xe — the xe device instance 🦋 like, the actual GPU device we're talking about here
• master_ctl — the interrupt register 💫 the raw register value carrying the interrupt info, hand it over as a u32

---

🧚 DESCRIPTION 🧚

so here's the vibe: this function takes the interrupts that the I2C host adapter generated 💖 and forwards them straight to the I2C host adapter driver 🫶 that's literally it — pure relay energy, no drama, no extra steps, periodt ✨

think of it as the group-chat admin forwarding a message to the right chat 😭 it doesn't read it, it doesn't reply, it just makes sure it lands where it needs to 💅

ngl it's a tiny function, but if you skip it the interrupts just sit there unforwarded and nobody's having a good time 💀
