outer_disable(9)

💅 outer_disable 💅

okay bestie so we're looking at outer_disable(9) from the Kernel API Manual today, and honestly? she's a small page with big main character energy. let's get into it 🫶

---

✨ NAME ✨

outer_disable — clean, invalidate and disable the outer cache. literally all three, she does the whole routine 💅

---

🦋 SYNOPSIS 🦋

void outer_disable (void );

that's it. that's the whole vibe check. returns void, takes void. no notes ✨

---

🎀 ARGUMENTS 🎀

• void — no arguments. none. zero. nada. she said "i need nothing from you" and honestly? respect 🙈

---

🌸 DESCRIPTION 🌸

so what does she actually do, you ask? she disables the outer cache 🔥 — and no, she doesn't just yeet it into the void, bestie. she makes sure that any data contained in the outer cache gets pushed out to lower levels of system memory first. clean, then invalidate, then disable. in that order. no cap.

💀 important caveat, don't skip this: the note and conditions above concerning outer_flush_all applies here too. so go read those, bestie, they're not decorative. iykyk.
