💅 dm_test_register_dmub_notify_callback_valid — Kernel API Manual ✨

okay bestie, buckle up, we're reading a kernel API manual page together and honestly? it's giving "niche but iconic." 🎀

🌸 NAME 🌸

dm_test_register_dmub_notify_callback_valid — literally just a test that checks the "register dmub notify callback" path is valid. that's it. that's the whole vibe. ✨

---

🦋 SYNOPSIS 🦋

void dm_test_register_dmub_notify_callback_valid(struct kunit *test);

no cap, that's the entire signature. returns void, takes one (1) pointer to a struct kunit, and honestly? she's lowkey elegant. 💜

---

🎀 ARGUMENTS 🎀

• test — the KUnit test context, aka the main character of this whole operation 👑 she's the one holding all the test state together, so put some respect on her name fr fr.

⭐ the cute sign-off ⭐

so this page comes from the source path ./drivers/gpu/drm/amd/display/... (yes, she's truncated with an ellipsis, that's just how the footer renders it, don't come for her 🙈), dated October 2026, and she answers to dm_test_reg...llback_valid(9) on the tin. slay. periodt. 💅🌸✨
