🎀 dm_test_add_modifier_grows_capacity(9)

okay so first things first: this page lives in the Kernel API Manual, and it's a KUnit test doc, which honestly makes it kind of niche-but-iconic. it's short, it's sweet, and it's doing one very specific thing. let's get into it 💖

✨ NAME ✨

dm_test_add_modifier_grows_capacity — literally just verifying that adding to the modifier array triggers growth and keeps the old data around. bestie behaviour, honestly: grow without losing your past 🫶

🌸 SYNOPSIS 🌸

void dm_test_add_modifier_grows_capacity (struct kunit *test );

that's the whole signature. no surprises, no plot twists 💅

🦋 ARGUMENTS 🦋

  • test — the KUnit test context. that's it. that's the whole argument list. it's giving low-maintenance 👑

💜 DESCRIPTION 💜

okay so the actual vibe check here: this test verifies whether the modifier array's growth keeps the old data and appends the new data. both things. at the same time. no cap 🔥

like — grow the array, don't lose what was already in it, and put the new stuff at the end. that's the whole test. simple, correct, obsessed 🌟

🌈 SEE ALSO 🌈

bestie the SEE ALSO section is long and i mean LONG, so buckle up. if you want more of this exact energy, the kernel file lives here:

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

and here's the full squad of sibling tests — every single one, no skips, fr fr 🫡

ngl if you read that whole list out loud you deserve a snack 🍓

and that's the page!! sign-off time: this one came from ./drivers/gpu/drm/amd/display/..., dated October 2026, and it's filed under dm_test_add...ows_capacity(9) in case you need to find it again. ily, go write some passing tests 💖✨🎀
