fdt_finish_reservemap(9)

📦 version 7.3.1, in nixpkgs unstable

💖 fdt_finish_reservemap 💖

okay so bestie, this one lives in the Kernel API Manual and it's literally called fdt_finish_reservemap — the "wrap up the reserve map already" girlie ✨

🌸 NAME 🌸

fdt_finish_reservemap — completes the memory reserve map, like closing the group chat before the next phase starts 🎀

🦋 SYNOPSIS 🦋

int fdt_finish_reservemap (void *fdt );

✨ ARGUMENTS ✨

  • fdt — pointer to the device tree blob. that's the whole vibe, she points at the blob 💅

👑 DESCRIPTION 👑

so here's the tea ☕ fdt_finish_reservemap completes the memory reserve map section of the device tree blob during sequential write. like it's the final "k bye" of that section 🫶

and after you call this function? that's it, no cap — no more reserve map entries can be added 🙈 the door is closed, the sign is flipped to closed, and the blob moves on to the structure creation phase. main character energy shift, honestly ✨

🔥 RETURN 🔥

  • 0 — on success, slay 💅
  • -FDT_ERR_BADSTATE — if you're not in the correct sequential write state 😭 like bestie you're not even in the right phase rn
