scmi_sensor_reading_get(9)

✨ scmi_sensor_reading_get ✨

okay so bestie, this one lives in the Kernel API Manual and ngl it's a whole vibe: you want one sensor number, you get one sensor number. iconic. 💅

---

🌸 NAME 🌸

scmi_sensor_reading_get — literally just read a scalar sensor value 🎀

---

🦋 SYNOPSIS 🦋

int scmi_sensor_reading_get (const struct scmi_protocol_handle *ph , u32
sensor_id , u64 *value );

---

💖 ARGUMENTS 💖

• ph — the protocol handle, your little passport to the SCMI world 🫶
• sensor_id — the sensor ID, like the sensor's @ in the group chat
• value — where the 64bit sensor reading lands; that's the 64bit value sensor reading, bestie ✨

---

👑 DESCRIPTION 👑

so this function hands you back a single 64 bit reading value that represents the sensor value. periodt. 🔥

but here's the tea ☕: if the platform SCMI Protocol implementation and the sensor support multiple axis and timestamped-reads, this function just returns the first axis while dropping the timestamp value. it's giving "first slide in the carousel" energy, honestly 😭

so if you actually want the full set, use scmi_sensor_reading_get_timestamped instead to retrieve the array of timestamped multi-axis values. that's the main character version, iykyk 💜

---

⭐ RETURN ⭐

0 on Success 🎉

🌈 SEE ALSO 🌈

• Kernel file ./drivers/firmware/arm_scmi/sensors.c
• scmi_sensor_reading_get_timestamped(9)

---

🫶 friendly reminder: one axis only, timestamp dropped. if that's not the vibe you were going for, go say hi to the timestamped version instead 💅

and that's the whole page, bestie — straight from ./drivers/firmware/arm_scmi, October 2026 edition, scmi_sensor_reading_get(9). slay, go read some sensors 🧚💖
