STRUCT SCMI_SENSOR_AXIS_INFO(9)

🌸 struct scmi_sensor_axis_info — bestie's guide to one sensor axis 🌸

okay so this is a page from the Kernel API Manual, and ngl it's lowkey iconic: struct scmi_sensor_axis_info describes exactly ONE sensor axes. that's it. that's the whole vibe. one axis, all the deets, main character energy ✨

✨ NAME ✨

struct scmi_sensor_axis_info — describes one sensor axes 💅

---

🎀 SYNOPSIS 🎀

struct scmi_sensor_axis_info {
    unsigned int id;
    unsigned int type;
    int scale;
    char name[SCMI_MAX_STR_SIZE];
    bool extended_attrs;
    unsigned int resolution;
    int exponent;
    struct scmi_range_attrs attrs;
 };

like, look at her. so structured. so put together. 🫶

🦋 MEMBERS 🦋

• id — the axes ID. the little name tag of the axis, its whole identity fr fr 🪪
• type — the axes type. it gets chosen amongst one of enum scmi_sensor_class — so it's always one of those, no improvising 🎯
• scale — a power-of-10 multiplier that gets applied to the axis unit. a lil glow-up number for the units ✨
• name — a NULL-terminated string that's the axes name, exactly as advertised by the SCMI platform. it's giving official government name 🎀
• extended_attrs — flag that says "hey, there are additional extended attributes for this axes". a little yes/no situation 🙈
• resolution — extended attribute representing the resolution of the axes. set to 0 if it's not reported by this axes. (so 0 is the "no data, don't @ me" value 💀)
• exponent — extended attribute representing the power-of-10 multiplier that gets applied to the resolution field. set to 0 if it's not reported by this axes. besties resolution and exponent are literally a duo 🤝
• attrs — extended attributes representing the minimum and maximum values measurable by this axes. set to 0 if it's not reported by this sensor. (yes, this one says sensor — not axes — that's just how it's written, don't come for me 😭)

mwah 💋 — this one lives in ./include/linux, dated October 2026, and it's the struct scmi_...or_axis_info(9) page of the Kernel API Manual. go forth and describe exactly one axes 👑
