dm_test_set_...ut_tf_linear(9)

🎀 dm_test_set_...ut_tf_linear(9) — the kernel API manual, bestie edition 🎀

okay so real quick, this page lives in section 9 of the kernel API manual and it's called dm_test_set_...ut_tf_linear. yes the name is truncated with dots, no that's not a typo, that's just how the header renders it. we move 💅

---

✨ NAME ✨

dm_test_set_output_tf_linear — linear output without a LUT calculates degamma

that's the whole vibe. no LUT in sight, and the degamma still gets calculated. iconic behavior honestly 🦋

---

✨ SYNOPSIS ✨

void dm_test_set_output_tf_linear (struct kunit *test );

returns void, takes exactly one thing, that's it, that's the whole signature, slay 🫶

---

✨ ARGUMENTS ✨

• test — the KUnit test context. that's it. that's the argument. she's the main character of this function call 💖

✨ SEE ALSO ✨

Kernel file (the actual home of all this, right here):

and now, the friendship circle. the full squad. literally every one of these, no skips, no cuts, we're listing them all because bestie deserves the complete map 🗺️✨

ngl bestie, that list is a lot, but every single one of those is a real cross-reference so don't come for me about length 💀

and that's the page!! source/version path is ./drivers/gpu/drm/amd/display/... and the date on this baby is October 2026, so yeah, from the future, obviously 👑✨ bye bestie, go read some color management code 🍓🧚💜
