✨ hl_mmu_hr_fini(9) ✨

okay bestie, welcome to the Kernel API Manual page for hl_mmu_hr_fini(9) — this is the one where we yeet the MMU module into the void 💅

---

💖 NAME 💖

hl_mmu_hr_fini — release the MMU module. that's it, that's the vibe 🫶

---

🎀 SYNOPSIS 🎀

void hl_mmu_hr_fini (struct hl_device *hdev , struct hl_mmu_hr_priv
*hr_priv , u32 hop_table_size );

copy it exactly, bestie, no autocorrect shenanigans 🙈

---

🌸 ARGUMENTS 🌸

• hdev — habanalabs device structure. like, the whole device, the main character 👑
• hr_priv — MMU host resident private info. its private business, respect it 🧚
• hop_table_size — HOP table size. just the size, nothing more, nothing less ⭐

---

🦋 DESCRIPTION 🦋

so this function does the following, and we're gonna go through it together:

• Disable MMU in H/W. 🔥
• Free the pgt_infos pool. 🍓

⚠️ heads up! All contexts should be freed before calling this function. seriously, all of them. don't come crying to me if you skip this step 😭
