---

🌸 SYNOPSIS 🌸

unsigned long acpi_get_wakeup_address (void );

🫶 ARGUMENTS 🫶

• void — no arguments, like, none at all. it takes nothing and wants nothing 🙈

---

🦋 DESCRIPTION 🦋

Returns the physical address where the kernel should be resumed after the system awakes from S3. yep, that's the whole vibe: it hands you the address.

You'd want it, for example, for programming into the firmware waking vector. iconic behavior, honestly ✨
