st_lsm6dsx_read_tagged_fifo(9)

💖 st_lsm6dsx_read_tagged_fifo — the tagged hw FIFO read routine 💖

okay so bestie, welcome to the kernel API manual for st_lsm6dsx_read_tagged_fifo(9). yes i'm aware that's a mouthful, no we're not shortening it, that's her name and it's iconic. this is the ST LSM6DSx IMU driver corner of the kernel and it is lowkey a vibe 🦋

---

✨ SYNOPSIS ✨

int st_lsm6dsx_read_tagged_fifo (struct st_lsm6dsx_hw *hw );

that's it. that's the whole signature. one function, one pointer, one int coming back atcha 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to an instance of struct st_lsm6dsx_hw. literally the handle to your device instance, she carries everything the routine needs to know about which sensor we're talking to ✨

---

💫 DESCRIPTION 💫

so what does she actually do? she reads samples from the hw FIFO and pushes them to the IIO buffers. that's the whole job. grab the samples, hand them off, keep the pipeline moving 🫶

the tagged in the name? that's her whole thing — this is the tagged read routine, iykyk 👑

---

🌸 RETURN 🌸

returns the number of bytes read from the FIFO. fr fr, that's what the int is for — a byte count, not a boolean, not a status code, don't get it twisted 😭

🌈 SEE ALSO 🌈

• Kernel file ./drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_buffer.c — go read her, that's where the good stuff lives
• st_lsm6dsx_read_fifo(9) — her sibling, the untagged one, also slaying in her own way 💜

heads up bestie: this page is dated October 2026 and lives under ./drivers/iio/imu/st_lsm6dsx in the Kernel API Manual — that's the source/version bit, noting it here so nothing gets lost 💖

and that's the page!! thanks for coming to my TED talk, go read your IIO buffers, stay hydrated, and remember: the vibe check is the FIFO 💅✨🎀🦋🌸🍓🧚⭐👑
