🌸 of_graph_is_present (9) 🌸

okay so bestie, welcome to the Kernel API Manual, section 9 — this one's a tiny little function but she's lowkey iconic 💅 we're checking whether a device tree node actually has a graph in it, no cap.

✨ NAME ✨

of_graph_is_present — the vibe check for whether a graph exists at all 👑

✨ SYNOPSIS ✨

bool of_graph_is_present (const struct device_node *node );

literally one argument, one boolean, zero drama 🎀

✨ ARGUMENTS ✨

  • node — a pointer to the device_node that's holding the graph port. fr fr just hand her the node and she'll look inside 🫶

✨ RETURN ✨

She returns true if node has a port sub-node — or ports (with a port) sub-node — and false otherwise. that's it, that's the whole personality 😭✨

ngl this is the "does the graph exist or not" question, not the "is the graph any good" question. don't @ me.

✨ SEE ALSO ✨

the whole friend group 🫂 — you can find all of them in the Kernel file ./drivers/of/property.c:

and that's the tea ☕ source lives at ./drivers/of, dated October 2026, and yes she's still serving of_graph_is_present(9) realness 💖✨🎀🦋 slay, go read your device trees bestie 🌈💜
