validate_enumeration_input(9)

💖 validate_enumeration_input(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this one's a lil cutie from the HP BIOS config corner of the kernel and honestly? she's a vibe. it's validate_enumeration_input, and her whole job is literally just checking that the value you handed over is actually one of the possible values. no cap, that's it. gatekeeping, but make it kernel. 💅

✨ SYNOPSIS ✨

int validate_enumeration_input (int instance_id , const char *buf );

yes queen, that's the whole signature — takes an int and a const char *, gives you back an int. simple. iconic. 🎀

🌸 ARGUMENTS 🌸

• instance_id — the instance on which the input gets validated. like, which one are we checking, babe? this tells her. 🫶
• buf — the input value. the thing under the microscope. the main character, honestly. 💖

🦋 SEE ALSO 🦋

the whole friend group lives in the kernel file ./drivers/platform/x86/hp/hp-bioscfg/enum-attributes.c — go say hi to her siblings:

• hp_populate_enumeration_package_data(9)
• hp_populate_enumeration_buffer_data(9)
• hp_exit_enumeration_attributes(9)

ngl bestie, the SYNOPSIS line has a space before the comma in int instance_id , const char *buf — that's not me being messy, that's verbatim. copy it exactly or don't copy it at all. 😭

⭐ so yeah — that's the whole page! stay hydrated, validate your enumerations, and remember: this was validate_enumeration_input(9) from the Kernel API Manual, dated October 2026, with the source bits living under ./drivers/platform/x86/hp/hp-b... (the page footer really does truncate it like that, and I refuse to fix her 💀). periodt. 🌈👑
