✨ drm_kunit_display_mode_from_cea_vic ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's a lil helper from the DRM KUnit corner of the kernel, and honestly? it's giving "tiny function, big main character energy". let's get into it 🎀

---

🌸 NAME 🌸

drm_kunit_display_mode_from_cea_vic — return a mode for CEA VIC for a KUnit test

like, that's literally the whole job. it hands you a display mode. for a test. slay 💅

---

🦋 SYNOPSIS 🦋

struct drm_display_mode * drm_kunit_display_mode_from_cea_vic (struct
kunit *test , struct drm_device *dev , u8 video_code );

yes she's a function returning a struct drm_display_mode *, and yes you pass her three things. keep scrolling for the tea ☕

---

💜 ARGUMENTS 💜

• test — the test context object 🧪 like, the whole vibe of the test lives in here
• dev — the DRM device 🖥️ the actual star of the show
• video_code — the CEA VIC of the mode 🎞️ it's a u8, it's iconic, it picks which mode you get

---

🔥 DESCRIPTION 🔥

so what does she do? she creates a new mode matching the specified CEA VIC, specifically for a KUnit test ✨ that's it, that's the function.

and the best part? resources will be cleaned up automatically 🫶 no manual teardown, no crying over leaked memory, no "not me forgetting to free the thing" moments. she handles it. periodt.

---

👑 RETURN 👑

a new drm_display_mode on success 💖 or NULL on failure 😭 (yes, always check. always. ngl it's the bare minimum).

and that's the page, bestie 🎀 mwah 💋 — brought to you by the fine folks in ./drivers/gpu/drm/tests, dated October 2026, and titled drm_kunit_d...from_cea_vic(9) because apparently even manpage headers get the truncated-name treatment 🙈 stay hydrated, go write a test, and remember: if it returns NULL, that's not a vibe 💅✨
