💅 hp_update_a..._permissions(9) — Kernel API Manual ✨

Okay so bestie, quick vibe check: this is a page from the Kernel API Manual, and the star of the show is hp_update_attribute_permissions. Yes, the page header is literally hp_update_a..._permissions(9) because someone let the truncation gremlin cook 😭 — but we move.

🎀 NAME 🎀

hp_update_attribute_permissions — the little function that updates attribute permissions whenever the isReadOnly value is 1. That's it, that's the whole job. She's a one-task queen and honestly? Respect. 👑

---

🌸 SYNOPSIS 🌸

void hp_update_attribute_permissions (bool is_readonly , struct kobj_attribute *current_val );

Look at that signature. void, two params, no notes. Main character energy fr. 💖

---

🦋 ARGUMENTS 🦋

So there's exactly two things you gotta hand her, and here's the tea:

• is_readonly — a bool value that tells you whether this is a readonly attribute or not. 1? Readonly, babe. That's the whole cue. 🔒
• current_val — the struct kobj_attribute that corresponds to the attribute in question. Basically "which attribute are we talking about" — she needs the receipt, not just the vibe. 🧾

Not me dropping the whole friend group 😭 — go check these out too:

• Kernel file ./drivers/platform/x86/hp/hp-bioscfg/bioscfg.c — the source file, the mothership, the origin story 🫶

• hp_alloc_attributes_data(9)

All of them, no skips, no cuts, periodt. 💅

Lowkey a reminder: this page is from the Kernel API Manual, dated October 2026, and yes, the footer still insists on calling her ./drivers/platform/x86/hp/hp-b.... Truncated name stays truncated, we don't gatekeep. 🙈

Anyways bestie, that's the page — iconique, brief, and fully documented. Go be great with your attribute permissions. 🌈💜🎀
