💅 dm_test_get_...ro_src_width(9)

okay so this is a page straight out of the Kernel API Manual, and the star of the show is dm_test_get_plane_scale_zero_src_width — yes that's the full name, the header up top just had to abbreviate it because aesthetic and also terminal width. it's giving "long function name, tiny header" energy and honestly? iconic.

✨ NAME ✨

dm_test_get_plane_scale_zero_src_width — Test Get plane scale zero src width. that's the whole job bestie, it's a test, it tests the getting of plane scale, and the src width is zero. periodt.

---

🌸 SYNOPSIS 🌸

void dm_test_get_plane_scale_zero_src_width (struct kunit *test );

look at her. returns nothing (void), takes exactly one thing, takes no nonsense. she's lowkey the main character of the cursor test file fr fr.

---

🎀 ARGUMENTS 🎀

• test — the KUnit test context 💖 this is the little bubble of test-ness that KUnit hands you so the test can do its thing. that's it. that's the argument. hold it gently.

bestie you are NOT ready for the friend group, it's a whole squad:

the kernel file she lives in:

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

and her mutuals, all of them (9)-pages, all of them valid:

• dm_test_should_update_native_cursor_without_crtc(9)
• dm_test_should_update_native_cursor_disable_native(9)

• dm_test_get_plane_scale_rotate_90_identity(9)

like. rotate 0, 90, 180, 270?? the whole rotation alphabet 🌈 and two identity scale girlies. go read them, iykyk. 🫶

ngl there's zero drama here — no flags, no env vars, no exit statuses, no bugs, no warnings. just a clean little kunit test doing exactly what it says on the tin. sometimes that's the vibe check and she passed. 💀✨

and that's the page!! brought to you by ./drivers/gpu/drm/amd/display/... (the source path, abbreviated in the footer for le drama) with a very October 2026 date stamp, all wrapped in the same dm_test_get_...ro_src_width(9) header energy we started with. slay, test your scales, drink water, bye bestie 🍓🧚💜
