acpi_evaluat...failure_warn(9)

💅 acpi_evaluation_failure_warn — the kernel API manual (yes bestie, section 9)

okay so this is a page out of the Kernel API Manual, and honestly? it's short, it's sweet, and it's giving "quietly saving your whole boot log from being useless" 🌸 so let's get into it 🫶

---

✨ NAME ✨

acpi_evaluation_failure_warn — literally just logs a warning when an evaluation fails. that's it. that's the whole vibe check. 📋

---

🌈 SYNOPSIS 🌈

void acpi_evaluation_failure_warn (acpi_handle handle , const char *name
, acpi_status status );

note the void — it hands nothing back to you, it just says its piece and leaves. iconique. 💅

---

🎀 ARGUMENTS 🎀

• handle — the parent object handle 🧚 like, whose kid are we talking about here
• name — the name of the object whose evaluation has failed 😭 poor thing, name it so everyone knows which one flopped
• status — the status value returned by the failing object evaluation 💀 the receipt, essentially, proving it really did fail

lowkey that __acpi_handle_debug(9) at the front with the double underscore? main character energy. it's been through things. 🙈
