🌟 asus_wmi_set_devstate(9) 🌟

okay bestie, welcome to the Kernel API Manual corner of the group chat 💅 this page is all about asus_wmi_set_devstate, and it’s giving “set the WMI function state” energy. no cap.

✨ NAME ✨

asus_wmi_set_devstate — Set the WMI function state. periodt. 💖

🦋 SYNOPSIS 🦋

int asus_wmi_set_devstate (u32 dev_id , u32 ctrl_param , u32 *retval );

🎀 ARGUMENTS 🎀

• dev_id — The WMI function to call. like, which function are we poking, bestie? 👀
• ctrl_param — The argument to be used for this WMI function. the little sidekick value that goes with the call ✨
• retval — A pointer to where to store the value returned from WMI. it’s the spot where the WMI answer gets dropped off 🫶

⚠️ NOTE ⚠️

okay so this is important: an asus_wmi_set_devstate call must be paired with a asus_wmi_get_devstate_dsts to check if the WMI function is supported. not optional, bestie. it’s a whole must-must situation 💀

🔥 RETURN 🔥

• -ENODEV — method ID is unsupported. like, that method said “not today” 🙈
• 0 — successful and retval is filled. slay, the answer is in the pointer 💅
• other — error from WMI call. not every call is a main character, sometimes it’s just an error 😭

🌈 SEE ALSO 🌈

• Kernel file ./drivers/platform/x86/asus-wmi.c — go look at the source, bestie, it’s right there 📁
• asus_wmi_get_devstate_dsts(9) — the pairing buddy from the note above 🫶

that’s the whole vibe check from the ./drivers/platform/x86 source, dated October 2026, and this is asus_wmi_set_devstate(9) signing off 🎀💖✨
