STRUCT SI1145_DATA(9)

🌸 NAME 🌸

struct si1145_data — si1145 chip state data 💖

okay so bestie, welcome to the struct si1145_data(9) page from the Kernel API Manual. this is literally the state-data situation for the si1145 chip, and it's giving "tiny struct, big responsibilities." no cap ✨

✨ SYNOPSIS ✨

struct si1145_data {
    struct i2c_client *client;
    struct mutex lock;
    struct mutex cmdlock;
    int rsp_seq;
    const struct si1145_part_info *part_info;
    unsigned long scan_mask;
    bool autonomous;
    struct iio_trigger *trig;
    int meas_rate;
    u8 buffer[24];
 };

• client — I2C client. the whole reason we're here, honestly 🦋
• lock — mutex to protect shared state. guard the communal vibes 🔒
• cmdlock — Low-level mutex to protect command execution only. it's giving "small but mighty" energy 💅
• rsp_seq — Next expected response number or -1 if counter reset required. track the response era, iykyk 👑
• part_info — Part information. the lore 🌸
• scan_mask — Saved scan mask to avoid duplicate set_chlist. no duplicate drama, periodt ✨
• autonomous — If automatic measurements are active (for buffer support). main character energy when true 💀
• trig — Pointer to iio trigger. the trigger bestie 🎀
• meas_rate — Value of MEAS_RATE register. Only set in HW in auto mode. lowkey auto-mode-only behavior 🫶
• buffer — Used to pack data read from sensor. u8 buffer[24], the packing icon 🍓
