💅 armoury_attr_uint_store(9)

okay so bestie, welcome to the Kernel API Manual page for armoury_attr_uint_store(9) — literally the little sysfs-to-WMI integer pipeline, and we're gonna read it together, no cap 🫶

---

✨ NAME ✨

armoury_attr_uint_store — send an uint to a WMI method, but only if it's within min/max. That's the whole vibe check right there 💅

---

🌸 SYNOPSIS 🌸

ssize_t armoury_attr_uint_store (struct kobject *kobj , struct
kobj_attribute *attr , const char *buf , size_t count , u32 min , u32
max , u32 *store_value , u32 wmi_dev );

---

🎀 ARGUMENTS 🎀

• kobj — pointer to the driver object. that's it, that's the girl 🫶
• attr — pointer to the attribute that's calling this function.
• buf — the buffer we read from; it gets parsed into a uint type. yes, literally parsed. iconic.
• count — required by the sysfs attribute macros, so the callee just passes it in from its own attr. not us being extra, it's the macros 😭
• min — the minimum accepted value. go below this and it returns -EINVAL. disrespect will not be tolerated 💀
• max — the maximum accepted value. go above this and it also returns -EINVAL. same energy, other direction ✨
• store_value — pointer to where the parsed value should be stored. hold her gently 🎀
• wmi_dev — the WMI function ID to use.

---

🦋 DESCRIPTION 🦋

so the whole point of this function is being generic — it's designed so literally any "_store" attribute that works only with integers can just call it. lowkey the friend who always has the charger 🔥

integers headed to the WMI method get an inclusive range check, and if the value's out of range it returns an error. boundaries are healthy, bestie 🌈

if the value is valid and the WMI call is a success, then two things happen:

1. the sysfs attribute is notified 📣
2. if asus_bios_requires_reboot is true, then the reboot attribute is also notified 👑

so yeah — sometimes setting a number means "hey, reboot me." that's just how it is, don't shoot the messenger 💀

---

⭐ RETURN ⭐

either count, or an error. that's the whole menu, bestie 🍓
