💅 dm_test_verify_lut3d_alloc_adev(9) 💅

okay so bestie, you've found yourself in the Kernel API Manual, section 9, and this page is about dm_test_verify_lut3d_alloc_adev — that's the long one, yes, say it three times fast, i dare you. it lives in the AMD display test world and it's literally here to hand you an amdgpu_device with a DC attached and a 3D LUT cap of your choosing. iconic behavior tbh 🎀

✨ NAME ✨

dm_test_verify_lut3d_alloc_adev — Allocate adev with a DC and given 3D LUT cap 🦋

like, the whole job. allocating an adev, giving it a DC, and letting you pick the 3D LUT cap. periodt.

🌸 SYNOPSIS 🌸

struct amdgpu_device * dm_test_verify_lut3d_alloc_adev (struct kunit
*test , bool has_3dlut );

look at that signature. chef's kiss. 🔥

💖 ARGUMENTS 💖

  • test — the KUnit test context, aka the group chat where all of this is happening 💬
  • has_3dlut — the value that gets programmed into caps.color.dpp.hw_3d_lut. so like, you decide whether the 3D LUT is a yes or a no, and it gets written right there 🫶

👑 RETURN 👑

it returns an amdgpu_device with adev->dm.dc allocated. that's it, that's the gift. no cap. ✨

🌈 SEE ALSO 🌈

the whole Kernel file lives right here, bestie:

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

and now the guest list — every single one of these icons, no skipping, i checked twice 💅:

and that's the whole page, bestie. source is ./drivers/gpu/drm/amd/display/..., dated October 2026 — so go forth, allocate that adev, and slay 💜🧚‍♀️⭐
