dm_test_verify_lut3d_valid(9)

💖 dm_test_verify_lut3d_valid(9) 💖

okay so this is a page straight outta the Kernel API Manual, section 9, bestie — welcome to the LUT-verification corner of the DRM/KUnit universe 🦋

---

✨ NAME ✨

dm_test_verify_lut3d_valid — Correct shaper and 3D LUT sizes: must succeed

🎀 SYNOPSIS 🎀

void dm_test_verify_lut3d_valid (struct kunit *test );

🌸 ARGUMENTS 🌸

• test — the KUnit test context, aka the little vibe-check container that carries all the test state around 🫶

ngl the whole point here is "correct shaper and 3D LUT sizes: must succeed" — so if this one fails, something is genuinely not slaying 😭
