meson_sm_get_thermal_calib(9)

💅 NAME 💅

okay so bestie, welcome to <pink>meson_sm_get_thermal_calib</pink> — this lil function's whole job is to read thermal sensor calibration data. yes, thermal as in heat, calibration as in "we measured this so you don't have to guess." it's giving thermals, it's giving trustworthy, it's giving iykyk 🔥

this one lives in the Kernel API Manual, so you already know it's deep-in-the-kernel business, no cap.

✨ SYNOPSIS ✨

int meson_sm_get_thermal_calib (struct meson_sm_firmware *fw , u32
*trim_info , u32 tsensor_id );

three args, one int coming back atcha. simple. iconic. periodt. 🎀

🫶 ARGUMENTS 🫶

• fw — a pointer to the secure-monitor firmware. like, the actual handle to the firmware you're talking to. you gotta hand it over, that's the whole vibe. 🦋
• trim_info — a pointer where the returned calibration data gets stored. it's the little basket you hold out for the function to drop the goodies into. 💖
• tsensor_id — the sensor index, aka which sensor's calibration data you want to retrieve. bc bestie, there can be more than one sensor, and they don't all have the same tea. 🌸

🌈 RETURN 🌈

• 0 on success — slay, it worked. 👑
• a negative error code on failure — boo, something went wrong. 😭

go read those if you're obsessed with this whole secure-monitor friend group. highkey a good time. 💜

ok that's the whole page, no more lore, it's literally just: give it the firmware, give it somewhere to store the trim info, tell it which sensor, and check your return value. that's the vibe check and it passed. 💅✨

💀 mwah 💀 — written under ./drivers/firmware/meson, dated October 2026, and yeah that's meson_sm_get_thermal_calib(9) signing off. stay calibrated, bestie 🍓🎀🫶
