tsens_read_temp(9)

💖 NAME 💖

tsens_read_temp — grab temperature readings straight out of the hardware, bestie. This one's from the Kernel API Manual, and it's giving “thermal sensor core energy” fr fr.

---

✨ SYNOPSIS ✨

int tsens_read_temp (const struct tsens_sensor *s , int field , int
       *temp );

---

🎀 ARGUMENTS 🎀

• s — pointer to the sensor struct. Literally the sensor bestie we're reading from.
• field — index into the regmap_field array that points to the temperature data. iykyk.
• temp — temperature in deciCelsius, to be read from the hardware. Yes, deciCelsius, not Celsius — she's got her own units 💅.

---

🦋 DESCRIPTION 🦋

Okay so this function handles the temperature that comes back either in ADC code or in deciCelsius, depending on the IP version. That's the whole vibe: it deals with whichever format the hardware hands over. No cap.

---

🌸 RETURN 🌸

• 0 on success — slay.
• A negative errno gets returned in error cases — not the moment, but it happens 😭.
