🎀 NAME 🎀

hl_mmu_hr_alloc_hop — allocate HOP 💅

---

🌸 SYNOPSIS 🌸

struct pgt_info * hl_mmu_hr_alloc_hop (struct hl_ctx *ctx , struct
       hl_mmu_hr_priv *hr_priv , struct hl_hr_mmu_funcs *hr_func , struct
       hl_mmu_properties *mmu_prop );

🫶 ARGUMENTS 🫶

• ctx — pointer to the context structure. classic context moment ✨
• hr_priv — host resident private info structure. 🏠
• hr_func — host resident functions. 🔧
• mmu_prop — MMU properties. 🧚

💫 DESCRIPTION 💫

On success, this returns the pgt_info structure associated with the allocated HOP. Otherwise? NULL. That’s the whole vibe check 😭 no cap, that’s it.
