dm_test_help...ipped_height(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so bestie, this page lives in the Kernel API Manual, section 9, and it's all about one very specific little guy: dm_test_helper_check_state_bottom_clipped_height — which is literally just Verify bottom clipping. That's it, that's the whole job 🎀

✨ SYNOPSIS ✨

void dm_test_helper_check_state_bottom_clipped_height (struct kunit
       *test );

🌸 ARGUMENTS 🌸

  • test — the KUnit test context, aka the little backpack of state this test carries around with it 🎒

🦋 DESCRIPTION 🦋

so the vibe check here is simple, no cap: this one verifies whether a viewport that gets clipped by the bottom edge down to below the minimum height is properly rejected 💀 like, the test is making sure the system goes "nope, not today" when you try to shrink a viewport past the bottom-and-too-small line 🙈

that's genuinely the whole thing, and honestly? iconic ✨

🔥 SEE ALSO 🔥

the kernel file itself lives right here, bestie 👇

and here's the whole friend group, in order, all 73 of them, periodt 💅

and that's the whole page, bestie 🫶 source situation is ./drivers/gpu/drm/amd/display/..., dated October 2026, and the manual page itself is dm_test_help...ipped_height(9) — go forth and clip responsibly 💖✨🎀
