💫 imgu_mmu_tlb_invalidate(9) 💫

okay so bestie, welcome to the Kernel API Manual — this one's a little function with a big job and honestly it's giving "quiet luxury" energy. Let's get into it 🎀

---

🌸 NAME 🌸

imgu_mmu_tlb_invalidate — invalidate translation look-aside buffer

like, the whole TLB. gone. poof. ✨

---

🦋 SYNOPSIS 🦋

void imgu_mmu_tlb_invalidate (struct imgu_mmu *mmu );

that's it. that's the whole vibe. one arg, no return value, no drama 💅

---

🍓 ARGUMENTS 🍓

• mmu — the MMU you're doing the invalidate operation on. yes queen, this is the one you're yeeting the TLB for 🫶

---

🔥 DESCRIPTION 🔥

So this function invalidates the whole TLB. Not part of it, not a lil' slice — the whole thing. no cap.

⚠️ Important bestie: it must be called when the hardware is powered on. Like, the hardware has to be awake for this to make sense — don't come at it while it's asleep, that's not the move 😭
