hl_mem_mgr_fini(9)

💖 hl_mem_mgr_fini — kernel API manual, bestie edition 💖

okay so we're in the hl_mem_mgr_fini(9) page, part of the Kernel API Manual, and honestly? this one is short and sweet and we love that for us. let's get into it ✨

🌸 NAME 🌸

hl_mem_mgr_fini — release unified memory manager

like, she's done, she's logging off, she's releasing the whole unified memory manager. periodt 💅

---

🎀 SYNOPSIS 🎀

void hl_mem_mgr_fini (struct hl_mem_mgr *mmg , struct
hl_mem_mgr_fini_stats *stats );

no return value, she gives you nothing back and that's the vibe 🦋

---

💜 ARGUMENTS 💜

• mmg — the parent unified memory manager. the mom of the whole situation, the main character we're shutting down 🫶
• stats — if this one's non-NULL, it will return some counters for handles that could not be removed. so if some handles just refused to leave the party 🙈, this is where you find out how many. if it's NULL, no counters for you, and that's fine too.

---

⭐ DESCRIPTION ⭐

Release the unified memory manager. that's it, that's the whole thing, she's iconic for keeping it brief 👑

Big important note bestie: this shall be called from an interrupt context. not a regular context, an interrupt context. don't get cute about it 😭🔥
