💅 dm_test_pp_to_dc_clock_levels_caps_at_max — like, the dm_test_pp_..._caps_at_max(9) page, bestie

okay so this page lives in the Kernel API Manual and it's about one very specific little KUnit test. she's niche, she's iconique, let's get into it 🎀

✨ NAME ✨

dm_test_pp_to_dc_clock_levels_caps_at_max — literally just "Test count capping at max." that's the whole vibe. 🫶

🌸 SYNOPSIS 🌸

void dm_test_pp_to_dc_clock_levels_caps_at_max (struct kunit *test );

that's it. one function. no return value. gone but not forgotten 💅

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 💖 she's the main character here, the whole group chat, the girlies' collective memory of what's happening in this test.

🔥 DESCRIPTION 🔥

okay so picture this: pp_to_dc_clock_levels gets handed a level count that's way too big — like, exceeding the max, no cap, she's trying to be more than she can be 😭 — and this test is here to verify that she caps num_levels at DM_PP_MAX_CLOCK_LEVELS. like the function knows its limits. boundaries, bestie. we love to see it. ✨👑

fr fr, the whole point: input count exceeds the maximum → the output count gets capped at DM_PP_MAX_CLOCK_LEVELS. verified. slayed. periodt. 💅

👑 SEE ALSO 👑

the kernel file for all this lives at:

and now, the rest of the squad — everybody else at the party (yes, all of them, I'm not skipping a single one, who do you think I am 😤):

like I said. everyone. iykyk 🌈

and that's the page, babe 🧚 source/version is ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — she's from the future, she's mysterious, she's dm_test_pp_..._caps_at_max(9) and we're obsessed. byeee 💜✨
