dm_test_psr...ed_null_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the manpage for dm_test_psr_is_active_allowed_null_link 🎀 — yes that's the whole name, it's giving "my mom picked it" energy but we move. This lives in the Kernel API Manual, section 9, and the vibes are immaculate: it's a KUnit test, no cap.

✨ NAME ✨

dm_test_psr_is_active_allowed_null_link — literally just here to prove that streams without links get skipped. that's it. that's the whole test. and honestly? iconic. 💅

🦋 SYNOPSIS 🦋

void dm_test_psr_is_active_allowed_null_link (struct kunit *test );

no return value, void queen, she gives nothing back and we respect her for it 🫶

🌸 ARGUMENTS 🌸

  • test — the KUnit test context. that's the little bubble of world-state KUnit hands you so you can assert stuff. your main character prop, basically 👑

🌈 SEE ALSO 🌈

okay so this is the squad — the whole friend group of related 9 pages, all listed in the kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_psr_test.c ✨

like, go read them too?? they're all right there in the same file, iykyk 💖

lowkey a reminder bestie: the only thing this test does is handle the null link case — streams with no link are skipped. don't go inventing extra behaviour for it, that's not the assignment 🙈

and that's the page!! 🌟 sign-off time: this beauty ships from the source path ./drivers/gpu/drm/amd/display/..., dated October 2026, under the same dm_test_psr...ed_null_link(9) header it came in with. slay, bye, ily, read your kernel tests 💜🧚‍♀️🍓
