💖 sensor_hub_register_callback(9) 💖

okay bestie, welcome to the Kernel API Manual, where we're about to make registering client callbacks make so much sense. this is sensor_hub_register_callback and it is lowkey the main character of the sensor hub core driver world 🌸

✨ NAME ✨

sensor_hub_register_callback — Register client callbacks 🎀

🦋 SYNOPSIS 🦋

int sensor_hub_register_callback (struct hid_sensor_hub_device *hsdev ,
u32 usage_id , struct hid_sensor_hub_callbacks *usage_callback );

like, that's the whole vibe. three args, one int coming back at you ✨

🌸 ARGUMENTS 🌸

  • hsdev — the Hub device instance. your actual hub, your icon, your moment 👑
  • usage_id — the usage id of the client. e.g. 0x200076 for Gyro. yes that's literally the gyro one, iykyk 💅
  • usage_callback — Callback function storage. this is where the callbacks go to live, like a lil shelf for your functions 🎀

💜 DESCRIPTION 💜

so this is the function the client processing drivers call to register their callbacks — that's the whole point. 🫶

then the sensor hub core driver will call those callbacks to offload processing of data streams and notifications. like the core driver is handing off the work, and honestly? slay, delegation is a skill 💅✨

tl;dr: you register, the core driver calls, the data streams and notifications get processed. periodt. 🔥

🌈 SEE ALSO 🌈

ngl bestie, that's a lot of SEE ALSOs — read them, they're all in the same little family 🧚‍♀️💖

and that's the page!! 🎀 sign-off time: this lil beauty lives over in ./include/linux, it's dated October 2026, and it's forever known as sensor_hub_r...ter_callback(9) — yes the title is truncated, that's just how the manpage wears it, and we're obsessed with it anyway 💜⭐🍓
