okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for mmu_invalidate_cache_all, and honestly? it's giving "small but mighty." ✨

🌸 NAME 🌸

mmu_invalidate_cache_all — invalidate the page table cache of all MMUs. every single one of them. no MMU left behind. 💖

---

🎀 SYNOPSIS 🎀

void mmu_invalidate_cache_all (void );

that's it, that's the whole signature. she's a void returning, void-taking icon. 👑

---

⭐ ARGUMENTS ⭐

• void — no arguments. nada. zero. the function takes nothing and she is thriving about it. 🫶

---

🦋 RETURN 🦋

none — she returns nothing, because the real reward was the caches we invalidated along the way. 😭💜

if you're obsessed (and you should be), go check out the kernel file:

./drivers/staging/media/atomisp/pci/hive_isp_css_include/host/mmu_public.h

and then fall down the rabbit hole with her besties:

• mmu_set_page_table_base_index(9)
• mmu_get_page_table_base_index(9)
• mmu_invalidate_cache(9)
• mmu_reg_store(9)
• mmu_reg_load(9)

lowkey a whole friend group. iykyk. 💅

fr fr, this one invalidates the cache for every MMU — not just one — so don't go thinking it's the cute little single-MMU version. that one's mmu_invalidate_cache(9). 🙈
