dm_test_mccs...et_null_link(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

Okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're fancy here ✨ — and today's main character is dm_test_mccs_vcp_set_null_link, which does exactly one thing:

  • dm_test_mccs_vcp_set_null_link — Test early return with NULL link

That's it. That's the whole flex. It's a KUnit test whose entire personality is "what happens when link is NULL" and honestly? Iconic. Lowkey the bravest thing a test can do 🫶

✨ SYNOPSIS ✨

void dm_test_mccs_vcp_set_null_link (struct kunit *test );

Look at her. One function, one parameter, zero drama. Ate and left no crumbs 💅

🎀 ARGUMENTS 🎀

  • test — The KUnit test context. That's the group chat she's reporting back to, fr fr.

🔥 SEE ALSO 🔥

Okay so this section is long, and no, I'm not skipping any of it — every single sibling test gets their moment, periodt 👑

First up, the actual file she lives in — your "Kernel file", if you will:

  • ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_helpers_test.c

And now the whole extended friend group, all of them, in order, no cuts 🧚:

Like, that's a whole soccer team of tests and every one of them is invited to the party 🎉 ngl, reading all of those out loud is a cardio workout.

💀 Friendly reminder bestie: the (9) at the end of every one of those names is the manual section, not part of the function name. Don't come for me, I'm just the messenger 🙈

And that's the page, diva 💖 Source and version vibes come from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so yes, this lil test is living in the future and thriving ⭐ Slay, dm_test_mccs_vcp_set_null_link, you absolute queen 👑 🦋
