unmap_phys_pg_pack(9)

💅 unmap_phys_pg_pack(9) 💅

Okay bestie, welcome to the Kernel API Manual ✨ — this is the page for unmap_phys_pg_pack, and no cap, the name literally tells you everything: it unmaps the physical page pack 🎀. That's the whole vibe. It's giving "cleanup era." 🧹

---

✨ SYNOPSIS ✨

void unmap_phys_pg_pack (struct hl_ctx *ctx , u64 vaddr , struct
hl_vm_phys_pg_pack *phys_pg_pack );

So it returns void (nothing back, she's not a gossip 💅) and it takes three things. Copy it exactly, don't be creative, this is not the moment for creative liberties 🔥.

---

🌸 ARGUMENTS 🌸

• ctx — pointer to the context structure. Your lil context bestie 🫶, the one holding the whole situation together.
• vaddr — start address of the virtual area to unmap. Like, the beginning of the region we're saying bye to 👋.
• phys_pg_pack — the pack of physical pages to unmap. Yes, the whole pack. Iconic, honestly 👑.

Lowkey important: it's void and there's no return value listed, so don't go looking for a status code, bestie, it's not coming 😭.
