STRUCT SENSOR_HUB_PENDING(9)

💖 struct sensor_hub_pending(9) — Kernel API Manual 💖

okay bestie, we're opening up the Kernel API Manual entry for struct sensor_hub_pending(9) — synchronous read pending information, and honestly? it's giving organized queen energy. every field is here, every ref is here, we are not skipping a single crumb. 🫶

✨ NAME ✨

struct sensor_hub_pending — Synchronous read pending information. that's the whole name vibe, and yes it ate. 💅

🦋 SYNOPSIS 🦋

here's the struct, copied exactly because code gets zero improv from me:

       struct sensor_hub_pending {
           bool status;
           struct completion ready;
           u32 usage_id;
           u32 attr_usage_id;
           int raw_size;
           u8 *raw_data;
           u32 index;
           u32 max_raw_size;
        };

🌸 Members 🌸

okay so these are the members, and each one is doing its little job:

• status — pending status true/false. simple, clean, main character energy.
• ready — completion synchronization data. it's giving "wait for it" energy.
• usage_id — usage id for physical device, e.g. gyro usage id.
• attr_usage_id — usage Id of a field, e.g. X-axis for a gyro. yes bestie, the specific field.
• raw_size — response size for a read request.
• raw_data — place holder for received response. (the little spot where the response goes)
• index — current write index into raw_data for multi-byte reads.
• max_raw_size — total buffer size for multi-byte reads; 0 for single-value reads. important little 0, do not lose it.
