💅 dm_test_oriented_plane_size_rotate_0 — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual entry for dm_test_oriented_plane_size_rotate_0, and honestly? It's giving very specific, very niche, very iconic. 🎀

---

🌸 NAME 🌸

dm_test_oriented_plane_size_rotate_0 — literally here to Test Oriented plane size rotate 0. That's the whole job. That's the assignment. Slay. 💖

---

✨ SYNOPSIS ✨

void dm_test_oriented_plane_size_rotate_0 (struct kunit *test );

no cap, that's the entire signature — a void function taking one single argument. Clean. Minimal. Main character energy. 👑

---

🫶 ARGUMENTS 🫶

• test — The KUnit test context 💫 — it's the little context bubble this test runs inside, and you literally cannot do the thing without it.

---

🦋 SEE ALSO 🦋

like, go look at the Kernel file first, bestie, fr fr:

• Kernel file
• ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_cursor_test.c
• dm_test_should_update_native_cursor_without_crtc(9)
• dm_test_should_update_native_cursor_disable_native(9)

• dm_test_get_plane_scale_identity(9)
• dm_test_get_plane_scale_rotate_90_identity(9)
• dm_test_get_plane_scale_zero_src_width(9)

the way this whole little friend group of tests is just rotating and scaling through life together 😭 — 90, 180, 270, and our girl rotate 0 holding down the baseline. 💀🔥

---

ngl, if you're here you probably want the neighbours too — the _rotate_90, _rotate_180, and _rotate_270 ones are right above, and the cursor tests are all hanging out in that same file. iykyk. 🌈

---

that's the whole page, bestie — no hidden lore, no extra flags, nothing sneaky. just one test, one context, and a whole lot of plane-size-rotate-0 devotion. 🧚

sign-off time: this little gem lives in the source at ./drivers/gpu/drm/amd/display/... and the page is dated October 2026 🌸 — so yeah, she's from the future and she's still rotating 0 degrees. periodt. 💜🎀
