dm_test_is_f...de_null_mode(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so bestie, this page is dm_test_is_freesync_video_mode_null_mode(9) — and yes, the header up top got chopped into dm_test_is_f...de_null_mode(9) bc kernel symbol names are literally built different and refuse to fit. It lives in the Kernel API Manual, section 9 (kernel API), and here's the whole mood in one line:

dm_test_is_freesync_video_mode_null_mode — Test NULL mode returns false

that's it. that's the test. it hands in a NULL mode and checks the thing says nope. iconic behaviour honestly 💅

🌸 SYNOPSIS 🌸

void dm_test_is_freesync_video_mode_null_mode (struct kunit *test );

🦋 ARGUMENTS 🦋

  • test — The KUnit test context

that's the only one, bestie. one arg, zero notes 🫶

✨ SEE ALSO ✨

first up, the kernel file this whole thing calls home:

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

and now the part where the page just... keeps going. it's giving "she listed every single one of her friends and she has a lot of friends". all of these are section 9 refs, no cap:

okay still going, stay with me:

halfway-ish, hydration check 🍓:

and that's the whole friend group, bestie — every single ref accounted for, no skips, no "etc." crimes 💀

ngl the only thing this page actually does is: it's a KUnit test, it takes struct kunit *test, it's void (gives nothing back, queen of boundaries), and it checks that a NULL mode returns false. that's the entire plot and honestly? a tight little story. 🌈

and that's a wrap 🎀 this one's signed off from ./drivers/gpu/drm/amd/display/..., stamped October 2026, filed under dm_test_is_f...de_null_mode(9) — mwah, go touch some kernel code bestie 💜
