STRUCT HID_SENSOR_HUB_CALLBACKS(9)

👑 struct hid_sensor_hub_callbacks(9) — Kernel API Manual 👑

okay bestie, welcome to the Kernel API Manual for struct hid_sensor_hub_callbacks(9) — literally the group chat of client callback functions, and everyone's invited 💅

---

✨ NAME ✨

struct hid_sensor_hub_callbacks — Client callback functions 🫶

like, these are the functions your client driver hands over so the sensor hub can hit it up later. no cap.

---

🎀 SYNOPSIS 🎀

struct hid_sensor_hub_callbacks {
    struct platform_device *pdev;
    int (*suspend)(struct hid_sensor_hub_device *hsdev, void *priv);
    int (*resume)(struct hid_sensor_hub_device *hsdev, void *priv);
    int (*capture_sample)(struct hid_sensor_hub_device *hsdev, u32 usage_id, size_t raw_len, char *raw_data, void *priv);
    int (*send_event)(struct hid_sensor_hub_device *hsdev, u32 usage_id, void *priv);
 };

she's giving struct, she's giving function pointers, she's giving main character energy 🌟

🦋 Members 🦋

• pdev — Platform device instance of the client driver. that's her home base, her little anchor to reality 🏠
• suspend — Suspend callback. gets called when things go sleepy bye 😴
• resume — Resume callback. and this one's the wake-up call, rise and shine ☀️
• capture_sample — Callback to get a sample. literally "gimme a data sample" energy 🍓
• send_event — Send notification to indicate all samples are captured, process and send event. the whole "okay we got everything, now go process and send the event" moment — iconic, honestly 🔥

lowkey everything here is just function pointers waiting for their moment. respect the pointer, bestie 💀

okay that's the whole page, no notes 💖 this came out of ./include/linux, dated October 2026, and she answers to the name struct hid_...ub_callbacks(9). mwah 💋🧚
