💅 dm_test_shou...able_overlay(9) — a whole Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual, where the function names are long enough to need their own zip code and the vibes are, frankly, immaculate. today's main character is dm_test_shou...able_overlay(9) — yes that's the abbreviated version, no we will not be shortening it further, it's giving "my name is a paragraph" energy and honestly? iconic. 🎀

---

✨ NAME ✨

dm_test_should_update_native_cursor_enable_overlay — a test that checks the enable path reads the new CRTC cursor mode. that's it, that's the whole assignment. it's a KUnit test, it does one little thing, and it slays at it. 🦋

---

✨ SYNOPSIS ✨

void dm_test_should_update_native_cursor_enable_overlay (struct kunit *test );

literally just that one line, bestie. takes a single struct kunit * and returns void — no notes, no drama, no return value to worry about. 🫶

---

✨ ARGUMENTS ✨

• test — the KUnit test context. it's the little ✨ context bubble ✨ this test lives inside, and yeah, it's the only thing you gotta hand over. lowkey the easiest argument list you'll see all day. 💖

✨ SEE ALSO ✨

okay so this is the friend group, and they're all in the same file, so you know they're close. 💀

Kernel file

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

and the rest of the squad, in the order the original lists them (respect the order, it's not a suggestion, it's a lifestyle):

• dm_test_should_update_native_cursor_without_crtc(9)
• dm_test_should_update_native_cursor_disable_native(9)
• dm_test_oriented_plane_size_rotate_0(9)
• dm_test_oriented_plane_size_rotate_90(9)
• dm_test_oriented_plane_size_rotate_180(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)

like, the rotate ones went 0 → 90 → 180 → 270 and honestly that's just a perfect quarter-turn arc, we love a consistent queen. 🔥

ngl, this page is short because the test is short — nothing dangerous, nothing deprecated, nothing undefined here. just a clean little enable-path vibe check. 🌸

and that's the whole page, bestie!! 🧚 no cap, you now know everything this manpage knows.

sign-off time: this came from ./drivers/gpu/drm/amd/display/... and it's dated October 2026, under the Kernel API Manual umbrella — so like, future-dated and still relevant, we love a forward-thinking icon. 👑💜
