lazy_mmu_mode_pause(9)

✨ lazy_mmu_mode_pause(9) — the pause button for lazy MMU mode ✨

okay so bestie, welcome to the lazy_mmu_mode_pause(9) page from the Kernel API Manual. this is the function that pauses lazy MMU mode, and she is very specific about her plans 💅

---

🌸 NAME 🌸

lazy_mmu_mode_pause — pause the lazy MMU mode. that’s the whole vibe, no cap.

🦋 SYNOPSIS 🦋

void lazy_mmu_mode_pause (void );

🎀 ARGUMENTS 🎀

• void — no arguments. literally none. that’s it, that’s the list 🫶

💖 DESCRIPTION 💖

This function pauses the lazy MMU mode. If it is currently active, it disables it and calls arch_leave_lazy_mmu_mode. slay ✨

It must be paired with a call to lazy_mmu_mode_resume. Calls to the lazy_mmu_mode_* API have no effect until the matching resume call. so don’t leave her hanging, bestie 😭

It has no effect if called:

• While paused (inside another pause/resume pair)
• In interrupt context

lowkey important: “no effect” means no effect — those two cases are a whole “not today” from this function 💀
