💫 kunit_software_node_register(9) 💫

okay bestie, so this is a page from the Kernel API Manual — yes, that Kernel API Manual — and it's about kunit_software_node_register, which lowkey is a little icon in the kunit world. let's get into it 🎀

---

✨ NAME ✨

kunit_software_node_register — register a kunit-managed software node. yep, that's the whole vibe: you hand it a node, kunit takes care of it for you 🫶

---

🌸 SYNOPSIS 🌸

struct fwnode_handle * kunit_software_node_register (struct kunit *test
, const struct software_node *swnode );

copy that exactly, bestie, don't be cute with the signature 💅

---

🦋 ARGUMENTS 🦋

• test — the test context. it's the kunit test you're registering this node for, the whole reason any of this is happening ngl
• swnode — the software node you want to register. this is the actual thing, the main character of the operation ⭐

---

🧚 DESCRIPTION 🧚

so here's the tea: you call this, and it registers a test-managed software node, then hands you back its firmware node handle. that's it, that's the function 💖

and the best part? the software node gets unregistered automatically after the test case completes. not you having to clean up, not you having to remember anything — kunit handles it. it's giving responsible bestie energy, fr fr 👑

---

💜 RETURN 💜

it returns the firmware node handle of the registered software node… or IS_ERR on failure. so like, check your error codes, babe, don't just assume it slayed 😭

no cap, if it fails you get IS_ERR — that's your signal to handle it properly.
