tuner_probe(9)

💖 tuner_probe(9) — the kernel API manual, but make it make sense 💖

okay so bestie, welcome to the tuner_probe(9) page from the Kernel API Manual ✨ this one's all about sniffing out tuners on an I2C bus, and honestly? it's giving detective energy 🔍💅

---

🌸 NAME 🌸

tuner_probe — literally probes the existing tuners on an I2C bus 🫶

---

✨ SYNOPSIS ✨

int tuner_probe (struct i2c_client *client );

---

🎀 ARGUMENTS 🎀

• client — the i2c_client descriptor, aka the lil ID card for the device we're checking out 🪪

---

🦋 DESCRIPTION 🦋

so this routine goes around probing for tuners at the expected I2C addresses 👑 In most cases, if a device answers to a given I2C address, it just assumes that the device is a tuner. simple, iconic, no notes ✨

but on a few cases, you need an extra bit of logic to double check if the device is really a tuner, or to identify the tuner type — like on tea5767/5761 devices 🍵 that's the extra little vibe check for the devices that wanna be mysterious 🙈

heads up bestie 💀 During client attach, set_type is called by the adapter's attach_inform callback. set_type must then be completed by tuner_probe. no skipping steps, periodt 🔥
