dm_test_orie...e_rotate_180(9)

✨ dm_test_oriented_plane_size_rotate_180 — NAME ✨

okay so bestie, this is a page straight outta the Kernel API Manual, and the star of the show is dm_test_oriented_plane_size_rotate_180 — literally "Test Oriented plane size rotate 180". that's the whole name, no notes, it does exactly what it says on the tin 💅

---

🌸 SYNOPSIS 🌸

void dm_test_oriented_plane_size_rotate_180 (struct kunit *test );

it returns void (so like, nothing comes back, it's giving "the journey is the reward") and it takes exactly one thing. slay.

---

🎀 ARGUMENTS 🎀

• test — the KUnit test context. that's it, that's the whole argument. it's the little sandbox the test runs inside, and our function is just out here living its best life in it 🫶

🦋 SEE ALSO 🦋

okay so there's a whole friend group here, and honestly? iconic roster. the Kernel file lives at:

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

and these are the besties it hangs out with (all section 9, all in the dm_test_* clique):

• dm_test_should_update_native_cursor_without_crtc(9)
• dm_test_should_update_native_cursor_disable_native(9)
• dm_test_should_update_native_cursor_enable_overlay(9)
• dm_test_oriented_plane_size_rotate_0(9)
• dm_test_oriented_plane_size_rotate_90(9)
• dm_test_oriented_plane_size_rotate_270(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)

notice how 180 is lowkey the odd one out of the rotate squad — 0, 90, 270 are all here too, so if you're spiralling about a full rotation situation, the whole set has you covered 🌈

ngl there's no EXIT STATUS, no ENVIRONMENT, no BUGS section on this one — it's a short page and we are not inventing lore. what you see is what you get 💖

the cute sign-off 🧚

this page came from the source path ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so like, future vibes only ⭐ and the page itself is titled dm_test_orie...e_rotate_180(9), truncated exactly like that, no cap. mwah, go write some tests bestie 💜🔥
