octeon_flush_cache_mm(9)

💅 octeon_flush_cache_mm (9) — from the Kernel API Manual, bestie 💖

okay so picture this: you're on a MIPS Octeon box, you've got a whole memory context — like, an entire mm_struct — and its cached contents need to GO. That's this function. It's the "nuke everything for this mm" button, and honestly? iconic.

✨ NAME ✨

octeon_flush_cache_mm — flush all memory associated with a memory context. that's it, that's the whole job. no crumbs left behind. 🧹💅

---

🌸 SYNOPSIS 🌸

void octeon_flush_cache_mm (struct mm_struct *mm );

it's a void — so, like, it gives you nothing back 🫶 — and it takes exactly one thing, which brings us to:

---

🎀 ARGUMENTS 🎀

• mm — the memory context to flush. yes, that one. hand it your struct mm_struct * and it does the thing. this is the "which mm are we wiping" parameter, fr fr. 😭

🦋 SEE ALSO 🦋

friends of the family! go say hi:

• Kernel file ./arch/mips/mm/c-octeon.c — the ✨ source of truth ✨, all the lore lives here
• octeon_flush_icache_all_cores(9) — when you need every core's icache in on it
• octeon_flush_cache_range(9) — the ranged version, for when you're being ✨selective✨
• octeon_flush_cache_page(9) — tiny single-page energy, one page at a time 🍓

---

💀 real talk: this is the whole-context flush, so it's giving "main character energy" — it's big, it's broad, it's not subtle. the granular ones up there in SEE ALSO exist for a reason, iykyk.

okay that's the page, periodt. 🎀✨ no cap, you're now an Octeon cache-flush girlie.
