STRUCT ST_LSM6DSX_HW(9)

✨ NAME ✨

okay so this is struct st_lsm6dsx_hw(9) from the Kernel API Manual, and it's literally the ST IMU MEMS hw instance — main character energy for the ST IMU MEMS hardware, no cap. 💖

🦋 SYNOPSIS 🦋

here's the exact struct bestie, copy-paste vibes only:

       struct st_lsm6dsx_hw {
           struct device *dev;
           struct regmap *regmap;
           int irq;
           struct mutex fifo_lock;
           struct mutex conf_lock;
           struct mutex page_lock;
           u8 suspend_mask;
           u8 enable_mask;
           u8 fifo_mask;
           s64 ts_gain;
           u8 ts_sip;
           u8 sip;
           u8 irq_routing;
           u8 enable_event[ST_LSM6DSX_EVENT_MAX];
           u8 *buff;
           struct iio_dev *iio_devs[ST_LSM6DSX_ID_MAX];
           const struct st_lsm6dsx_settings *settings;
           struct iio_mount_matrix orientation;
           struct {
             __le16 channels[3];
             aligned_s64 ts;
           } scan[ST_LSM6DSX_ID_MAX];
        };

🎀 Members 🎀

• dev — pointer to the instance of struct device (I2C or SPI), aka the device itself. 🫶
• regmap — register map of the device, periodt.
• irq — device interrupt line (I2C or SPI) — that's the interrupt vibe. ⚡
• fifo_lock — mutex to prevent concurrent access to the hw FIFO, fr fr.
• conf_lock — mutex to prevent concurrent FIFO configuration update — no fighting over updates, bestie. 💅
• page_lock — mutex to prevent concurrent memory page configuration.
• suspend_mask — suspended sensor bitmask, simple as that.
• enable_mask — enabled sensor bitmask. ✨
• fifo_mask — enabled hw FIFO bitmask.
• ts_gain — hw timestamp rate after internal calibration — the calibration already ate. 🔥
• ts_sip — total number of timestamp samples in a given pattern.
• sip — total number of samples (acc/gyro/ts) in a given pattern.
• irq_routing — pointer to interrupt routing configuration. 👀
• enable_event — enabled event bitmask.
• buff — device read buffer.
• iio_devs — pointers to acc/gyro iio_dev instances. 🦋
• settings — pointer to the specific sensor settings in use — which settings? the ones in use, iykyk.
• orientation — sensor chip orientation relative to main hardware.
• scan — temporary buffers used to align data before iio_push_to_buffers. 🌸
