🎀 dm_test_com...ed_connector(9) 🎀

okay bestie so we're in the Kernel API Manual today and this page is literally about dm_test_com...ed_connector — say that five times fast, i can't 😭 anyway it's a KUnit test helper and it's giving "small function, very specific job" and honestly? we respect it.

---

✨ NAME ✨

dm_test_commit_audio_notifies_added_connector — the test for when a connector gets added and the audio notification should go off. that's it, that's the whole vibe 💅

🌸 SYNOPSIS 🌸

void dm_test_commit_audio_notifies_added_connector (struct kunit *test
);

like, it returns void — it's not here to give you answers, it's here to check things. main character energy fr fr 👑

🦋 ARGUMENTS 🦋

• test — the KUnit test context 🧪 like yeah it's just the context, but it's the context, you know? everything needs somewhere to live.

💖 DESCRIPTION 💖

so here's the lore: when a modeset enables a connector with a stream status, then commit_audio should do two things, no cap:

1. store the stream audio instance 🍓
2. notify the audio component for that pin 🔔

and that's the whole behaviour being tested. the test literally exists to vibe check that both of those happen. periodt ✨

ngl this one is a test, so if you're reading this hoping for a general-purpose function to call in your own code… it's not that, bestie 🙈 it's a KUnit test case.
