of_have_populated_dt(9)

💖 of_have_populated_dt(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny lil function with main character energy — it's literally just a vibe check on your device tree, no cap 🎀

---

🌸 NAME 🌸

of_have_populated_dt — bestie, it tells you whether the DT has been populated by the bootloader 👑

✨ SYNOPSIS ✨

bool of_have_populated_dt (void );

🦋 ARGUMENTS 🦋

• void — no arguments, periodt 💅 it takes absolutely nothing, she's low maintenance

🔥 RETURN 🔥

Returns True if a DTB has been populated by the bootloader and it isn't the empty builtin one 🫶

Returns False otherwise 🙈 that's it, that's the whole tea ☕

ngl the "and it isn't the empty builtin one" part is doing a lot of heavy lifting here — an empty builtin DTB does not count as populated, fr fr 💀
