💅 dm_test_get_default_ips_mode_dcn36 — ngl bestie, this one's a whole vibe

okay so real talk, this page is from the Kernel API Manual (yes, that Kernel API Manual, iconic) and it's about one (1) little KUnit test. She's tiny. She's specific. She's giving "one job, done correctly." Let's get into it 💖

---

✨ NAME ✨

dm_test_get_default_ips_mode_dcn36 — the test that checks the default IPS mode for dcn36, fr fr 🎀

---

🌸 SYNOPSIS 🌸

void dm_test_get_default_ips_mode_dcn36 (struct kunit *test );

that's it. that's the whole signature. no cap, she returns void and takes exactly one thing 🫶

---

🦋 ARGUMENTS 🦋

• test — the KUnit test context 💫 this is the little handle KUnit hands you so the test can do its test-y things. you don't invent one, you get handed one. respect the context, bestie.

like, that is a roster. the dcn36 girlies stay connected to the dcn35, dcn351, older-than-dcn35 and newer-default girlies, and honestly? the dmub hw_init / hw_resume / aux transfer crew ate too 🔥

heads up bestie: this page is short because the test is short. don't go looking for OPTIONS, there are none, and I refuse to invent them for content. 💀

and that's the whole page, my love 🌈 — the source path in the footer got cut off at ./drivers/gpu/drm/amd/display/..., it's dated October 2026, and it answers to the manual name dm_test_get_...s_mode_dcn36(9) (the title's own little abbreviation moment, iykyk). go off, kernel test 🎀✨💅
