STRUCT INV_SENSORS_TIMESTAMP(9)

🕐 struct inv_sensors_timestamp — timestamp management states ✨

okay bestie, so this is a page from the Kernel API Manual (the struct inv_s...rs_timestamp(9) one, iykyk) and it's literally just one struct that keeps track of all your timestamp bookkeeping. no cap, it's giving "small struct, big responsibilities" energy 💅

🌸 SYNOPSIS 🌸

here's the whole thing, verbatim, don't touch:

struct inv_sensors_timestamp {
    struct inv_sensors_timestamp_chip chip;
    u32 min_period;
    u32 max_period;
    struct inv_sensors_timestamp_interval it;
    struct inv_sensors_timestamp_interval delta;
    u32 delta_counter;
    s64 timestamp;
    u32 mult;
    u32 new_mult;
    u32 period;
    struct inv_sensors_timestamp_acc chip_period;
 };

💖 Members 💖

okay so let's go through every single field, no skipping, we're being thorough today 🫶

• chip — the chip's internal characteristics, like its whole personality profile tbh
• min_period — the minimal acceptable clock period (the floor, the bare minimum, the "don't go below this" line) ⭐
• max_period — the maximal acceptable clock period (the ceiling, the "don't exceed this" line)
• it — interrupts interval timestamps ✨
• delta — interval timestamps between several interrupts
• delta_counter — the number of data samples in the delta interval 🔥
• timestamp — stores the last timestamp, used for computing the next data timestamp (it's the memory of the struct fr fr)
• mult — the current internal period multiplier
• new_mult — the new set internal period multiplier, which is not yet effective 🙈 (it's on its way, it's just not there yet bestie)
• period — the measured current period of the sensor 🎀
• chip_period — accumulator for computing internal chip period

👑 SEE ALSO 👑

if you wanna keep reading (and you should, we love a deep dive), the Kernel file lives at ./include/linux/iio/common/inv_sensors_timestamp.h, and it's friends with:

• struct inv_sensors_timestamp_chip(9)
• struct inv_sensors_timestamp_interval(9)
• struct inv_sensors_timestamp_acc(9)

okay that's the whole page bestie, you ate that 💜

this gem dropped from ./include/linux/iio/common, dated October 2026, under the struct inv_s...rs_timestamp(9) banner — iconic, honestly. slay 🌈✨
