💅 dm_test_get..._mode_dcn351(9) — from the Kernel API Manual, bestie ✨

Okay so real talk, this is a page from the Kernel API Manual, and the star of the show is dm_test_get_default_ips_mode_dcn351(9). Buckle up, it's a whole vibe 🎀

---

✨ NAME ✨

dm_test_get_default_ips_mode_dcn351 — literally the test for Get default ips mode dcn351. That's it, that's the whole name, and honestly? Iconic.

---

🦋 SYNOPSIS 🦋

void dm_test_get_default_ips_mode_dcn351 (struct kunit *test );

Look at her go. Returns void, takes a struct kunit * named test, zero notes, we love a clean signature 💖

---

🌸 ARGUMENTS 🌸

• test — the KUnit test context, aka the little group-chat she's running in. That's the whole guest list, no plus-ones.

🫶 SEE ALSO 🫶

The kernel file where she lives, no cap:

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_dmub_test.c

Like, that's a squad. Forty-three of them plus this one, all living in amdgpu_dm_dmub_test.c, all doing their little KUnit slay 🔥

Quick vibe check: this page is API documentation for a test function, so there's no danger zone here — nothing deprecated, nothing undefined, just a void test hanging out with her besties 💜
