🌸 NAME 🌸

hl_mmu_v2_ctx_init — initialize a context for using the MMU module. that's it. that's the whole vibe 💅

🦋 SYNOPSIS 🦋

int hl_mmu_v2_ctx_init (struct hl_ctx *ctx );

literally just hand her a ctx and she does the rest, no cap 👑

---

💖 ARGUMENTS 💖

• ctx — pointer to the context structure to initialize. yes babe, the context structure. give her the pointer and let her cook 🫶

---

✨ DESCRIPTION ✨

so what she actually does: she initializes a mutex to protect the concurrent mapping flow 🔥 (translation: so multiple people aren't fighting over the same mapping at the same time, iconic behaviour tbh), and a hash to hold all page tables hops related to this context 🌈.

two whole things. mutex + hash. she's lowkey doing the most and we love her for it 😭💜
