✨ dm_test_fill_dc_scaling_info_plane_caps(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a KUnit test helper from the dm_test_fil...o_plane_caps(9) page (yes the title got cut off in the header, it's giving truncated-legend energy, but we move 🫶).

🎀 NAME 🎀

dm_test_fill_dc_scaling_info_plane_caps — literally here to verify the scaling caps path. that's it, that's the whole vibe check ✨

🌸 SYNOPSIS 🌸

void dm_test_fill_dc_scaling_info_plane_caps (struct kunit *test );

no cap, that's the whole signature, keep the spacing exactly like that 🧚

🦋 ARGUMENTS 🦋

  • test — the KUnit test context. your little test-world holder, your main character container 👑

💖 DESCRIPTION 💖

so the whole point: this test verifies if the scaling info actually uses plane caps when the state references a plane, a device, and a framebuffer. all three in the same room at the same time, iconic trio behavior 💅✨

that's the entire check. obsessed.

🌈 SEE ALSO 🌈

the kernel file in question lives at:

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

and these besties are all in the group chat too (do NOT skip a single one, i'm watching 👀):

and that's the whole page, bestie 💜 this cutie came from the source/version baked into the footer — ./drivers/gpu/drm/amd/display/..., dated October 2026 — so like, mark your calendar bestie, it's giving future-dated excellence 🌟👑 go write some tests, ily, bye 🎀🦋
