acpi_handle_printk(9)

💖 NAME 💖

okay so bestie, meet <acpi_handle_printk(9)> — she’s from the Kernel API Manual and her whole job is: Print message with ACPI prefix and object path. no cap, that’s the vibe 💅

---

🌸 SYNOPSIS 🌸

void acpi_handle_printk (const char *level , acpi_handle handle , const
       char *fmt , ... );

---

🎀 ARGUMENTS 🎀

• level — log level 👑
• handle — ACPI device handle 🦋
• fmt — format string ✨
• ... — variable arguments 🫶

---

💅 DESCRIPTION 💅

So this function gets called through the acpi_handle_<level> macros, and it prints a message with an ACPI prefix and object path. iconic behavior, honestly ✨

It also acquires the global namespace mutex to obtain an object path — yes, she’s doing the most for that path, and we respect it 🔥

Small but important tea: in interrupt context, it shows the object path as <n/a> 😭 periodt.
