hl_mmu_ctx_init(9)

🎀 NAME 🎀

okay bestie, welcome to the hl_mmu_ctx_init(9) page from the Kernel API Manual 💖 — this one is all about initializing a context for using the MMU module. That's the vibe. Periodt ✨

✨ SYNOPSIS ✨

int hl_mmu_ctx_init (struct hl_ctx *ctx );

🌸 ARGUMENTS 🌸

• ctx — pointer to the context structure to initialize. That's the whole arg, no cap 💅

🦋 DESCRIPTION 🦋

okay so hl_mmu_ctx_init does two very specific things, and we're obsessed: it initializes a mutex to protect the concurrent mapping flow, and it initializes a hash to hold all page tables hops related to this context. Literally that's the job. Slay 🫶

🫶 RETURN 🫶

0 on success, non-zero otherwise. Simple, iconic, no notes 🔥
