i2c_handle_smbus_alert(9)

✨ i2c_handle_smbus_alert(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a little helper from the i2c world and it's honestly so real of it. let's get into it 🎀

---

💅 NAME 💅

i2c_handle_smbus_alert — Handle an SMBus alert

like, the whole personality is right there in the name, no cap 🦋

---

🌸 SYNOPSIS 🌸

int i2c_handle_smbus_alert (struct i2c_client *ara );

she takes one thing and returns an int, periodt 👑

---

🎀 ARGUMENTS 🎀

• ara — the ARA client on the relevant adapter. that's it, that's the whole argument list, she's lowkey low-maintenance 💅

---

🧚 CONTEXT 🧚

can't sleep 😭

fr fr — this one runs in a context where sleeping is not allowed, so don't even think about it bestie 🙈

---

💜 DESCRIPTION 💜

okay so this is a helper function, and the way it works is you call it from an I2C bus driver's interrupt handler 🫶

it will schedule the alert work, which in turn calls the corresponding I2C device driver's alert function ✨ like it's passing the message along, main character energy all the way down the chain 👑

and it's assumed that ara is a valid i2c client previously returned by i2c_new_smbus_alert_device — so don't just be handing her any random thing, she trusts you on this one 🙈
