STRUCT LM75_PARAMS(9)

💅 struct lm75_params(9) 💅

okay so this is a page from the Kernel API Manual — yes THE Kernel API Manual, we're literally in the big leagues bestie 🎀 — and it's all about struct lm75_params, aka the little configuration-parameters glow-up kit for the lm75 driver. it's giving "let me introduce you to the settings" energy and honestly? obsessed.

✨ NAME ✨

struct lm75_params — the lm75 configuration parameters. that's it, that's the vibe. 🦋

🌸 SYNOPSIS 🌸

struct lm75_params {
    bool config_reg_16bits;
    u16 set_mask;
    u16 clr_mask;
    u8 default_resolution;
    u8 resolution_limits;
    const u8                *resolutions;
    unsigned int            default_sample_time;
    u8 num_sample_times;
    const unsigned int      *sample_times;
    bool alarm;
 };

like, copy it exactly, don't @ me — this is the whole struct, every field, periodt. 💅

👑 Members 👑

bestie, let's go field by field, because each one is a whole main character:

• config_reg_16bits — tells you the configure register size is 2 bytes. two. bytes. iconic.
• set_mask — the bits to set in the configuration register when you're configuring the chip. turning things ON energy 🔥
• clr_mask — the bits to clear in the configuration register when you're configuring the chip. turning things OFF energy, equally valid 💀
• default_resolution — the default number of bits used to represent the temperature value. how much detail the temp gets, basically.
• resolution_limits — limits the register resolution. it's optional, so no pressure 🫶. but you should set it if the resolution of the limit registers does not match the resolution of the temperature register. mismatched resolutions = not the vibe.
• resolutions — a list of resolutions associated with sample times. also optional ✨. you should set it if num_sample_times is larger than 1, and if the resolution changes with sample times. and if you do set it — the number of entries must match num_sample_times. no cap, they have to match.
• default_sample_time — the sample time that gets set by default. the pre-selected option, the default answer on the quiz 📝
• num_sample_times — the number of possible sample times to be set. this one's optional too 🌈. should be set if the number of sample times is larger than one.
• sample_times — all the possible sample times to be set. this one is mandatory if num_sample_times is larger than 1 🚨. and if set, the number of entries must match num_sample_times. same matching rule, fr fr.
• alarm — the alarm bit is supported. simple as that. 🚨✨

that's the whole page bestie, you ate that 💖 — this cutie came from the ./drivers/hwmon source, dated October 2026, and it's still serving struct lm75_params(9) realness to this day. mwah 🎀💜
