✨ get_slot_status(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's from the (9) section, which is giving "deep kernel lore, not for the faint of heart" energy 💅 and today's main character is get_slot_status.

---

🌸 NAME 🌸

get_slot_status — literally just, get the ACPI slot status 🎀

---

🦋 SYNOPSIS 🦋

unsigned int get_slot_status (struct acpiphp_slot *slot );

---

💖 ARGUMENTS 💖

• slot — your ACPI PHP slot ✨ that's it, that's the whole vibe, you hand her a slot and she tells you things about it 🫶

---

🔥 DESCRIPTION 🔥

okay so here's the tea, three scenarios, no cap ☕️

• If a slot has _STA for each function and any one of them returned a non-zero status — she returns it. periodt. 👑
• If a slot doesn't have _STA, and any one of its functions' configuration space is configured — she returns 0x0f as a _STA. iconic workaround behavior, honestly 🌈
• Otherwise? She returns 0. that's it. zero. the void. 💀
