hp_wmi_set_bios_setting(9)

📦 version 7.3.1, in nixpkgs unstable

💅 hp_wmi_set_bios_setting — like, the Kernel API Manual page, bestie ✨

Okay so gather round, because we're talking about hp_wmi_set_bios_setting(9) — a little function from the Kernel API Manual and honestly? She's giving "small but mighty." 🎀 Her whole thing is setting a setting's value in BIOS. That's it. That's the job. And she does it slayfully. 🌸

✨ NAME ✨

hp_wmi_set_bios_setting — Set setting's value in BIOS 🫶

Like literally, that's the whole vibe. She writes a value into BIOS. Iconic behavior, no notes. 👑

🦋 SYNOPSIS 🦋

int hp_wmi_set_bios_setting (u16 *input_buffer , u32 input_size );

That's her signature, character for character, do NOT touch it. 💖

🌈 ARGUMENTS 🌈

  • input_buffer — the Input buffer address, aka where the buffer lives. That's the spot. Show her the spot. 📍
  • input_size — the Input buffer size, aka how big that spot is. Gotta know the size, bestie, otherwise it's chaos. 😭

⭐ RETURN ⭐

So what does she give back? If everything's cute and successful, you get the count of unicode characters written to BIOS. Slay. 💅

But if things go sideways:

  • -ENOMEM — she couldn't allocate memory. The memory was simply not there. Devastating. 💀
  • -EINVAL — the buffer wasn't allocated, or it's too small. Like, girl, the buffer is not buffer-ing. 🙈
Heads up bestie: those are the negative returns, so if you see one, something genuinely went wrong — don't just vibe past it. 🚨

👑 SEE ALSO 👑

And that's the whole page, bestie — go forth and set those BIOS settings. 💖✨

This lil' beauty comes from ./drivers/platform/x86/hp/hp-b... and she's dated October 2026 — hp_wmi_set_bios_setting(9), forever and always. 🎀🫶
