dm_test_add...ll_edid_noop(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_add_freesync_modes_null_edid_noop

Okay so bestie, welcome to the Kernel API Manual ✨ — this little page (the header up top reads dm_test_add...ll_edid_noop(9), truncated and all, and honestly she's giving "name got cut off in the group chat preview") is about one single, extremely specific KUnit test. No cap, she's a whole unit test and she's here to tell you one (1) fact about EDID and FreeSync modes. Let's get into it 🫶

✨ NAME ✨

dm_test_add_freesync_modes_null_edid_noop — literally the test where a NULL EDID adds no modes 💀

🎀 SYNOPSIS 🎀

void dm_test_add_freesync_modes_null_edid_noop (struct kunit *test );

🌸 ARGUMENTS 🌸

  • test — the KUnit test context, i.e. the little test-shaped bestie this function gets handed to do its thing. That's it. That's the whole argument list 🎀

💖 DESCRIPTION 💖

Okay so here's the tea ☕: without an EDID, the FreeSync video modes cannot be derived. Like, there's just nothing to derive them from, the source material is missing, the vibe check fails.

So the mode count is left unchanged — noop is right there in the name and she is not lying to you. Nothing gets added. Nothing gets touched. The mode count stays exactly where it was. Iconic, honestly 👑

🦋 SEE ALSO 🦋

She has a lot of siblings. Like, an unreasonable number. Family reunion energy. Here they all are, in order, no skips, fr fr 🍓

And the kernel file she lives in (say hi to her house 🏠):

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_connector_test.c
Heads up bestie 🫶 — she's a test, not a syscall. There's no -h, no flags, no exit status, no environment variables here. Just one function, one argument, and one very chill "nothing happens" guarantee. 💅

Okay that's the whole page, mwah 💖 She's sourced from ./drivers/gpu/drm/amd/display/... and dated October 2026 — mark your calendars, that's the version stamp, periodt 🌈⭐
