dm_test_repl...ot_supported(9)

💅 NAME 💅

Bestie, the header on this one literally reads dm_test_repl...ot_supported(9) — yes it's cut off mid-word, the man page is giving truncated main character energy 💀 — and it's from the Kernel API Manual, section 9. The actual function behind the ellipsis is dm_test_replay_set_caps_link_not_supported, and its entire personality is: verify capability rejection ✨ periodt.

🎀 SYNOPSIS 🎀

void dm_test_replay_set_caps_link_not_supported (struct kunit *test );

(Not me leaving that space before the closing paren exactly as it is — character for character, no cap 🫶)

---

🦋 ARGUMENTS 🦋

• test — the KUnit test context 🧪. That's the whole input, that's the vibe, one single argument.

---

🔥 DESCRIPTION 🔥

Okay so here's the tea 👑: when amdgpu_dm_link_supports_replay rejects the link, the higher-level Replay setup helper should also return false. That's it. That's the test.

Like, both layers gotta agree, fr fr — if the low-level check is out here saying nope, the high-level helper cannot be saying yes, that would be a whole mess and we do not stan 😭

And that's the page, bestie 🎀✨ This one came from ./drivers/gpu/drm/amd/display/... and the footer says October 2026, signed off with dm_test_repl...ot_supported(9) all over again — iconic, honestly. Go forth and reject some capabilities 💅🦋
