dm_test_enab...ignores_link(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

dm_test_enable_assr_uninitialized_dtm_ignores_link — bestie, this test is literally about not touching the link when things fail.

This page lives in the Kernel API Manual (section 9), and the title up top got chopped to dm_test_enab...ignores_link(9) because man page headers are dramatic like that. Same test tho. 🫶

✨ SYNOPSIS ✨

void dm_test_enable_assr_uninitialized_dtm_ignores_link (struct kunit
*test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. The little test-scenario backpack this whole thing rides in on. 🧚

🌸 DESCRIPTION 🌸

okay so picture this: we're on the "DTM TA not initialized" path. On that path, enable_assr bails out before it ever reads a single field of link.

which means — and this is the whole vibe check — a NULL link must be tolerated. No crash, no drama, no segfault arc. Not even one little peek at the struct. 🙈

and the call must still return false. That's it, that's the test. The link is left completely untouched on failure, which is exactly the point. No cap. 💅

👑 SEE ALSO 👑

The kernel file this whole thing calls home:

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

and the full friend group of related pages, all present and accounted for (no skipping, bestie, we list every single one 🍓):

okay that's the whole page, you ate that bestie 💖 this one shipped out from ./drivers/gpu/drm/amd/display/... back in October 2026, and the page itself answers to dm_test_enab...ignores_link(9) — iconic, truncated, slay. 🌈⭐
