👑 dm_test_aud...ng_connector(9) — the kernel API manual glow-up ✨

okay so bestie, welcome to the dm_test_aud...ng_connector(9) page 💅 this is a Kernel API Manual entry, and yes the title is giving "abbreviated by someone who ran out of terminal width" but we move 🫶

🌸 NAME 🌸

dm_test_audio_component_get_eld_copies_matching_connector — the Test ELD lookup girly ✨

like, that's literally her whole job. no cap.

---

🎀 SYNOPSIS 🎀

void dm_test_audio_component_get_eld_copies_matching_connector (struct
kunit *test );

she takes one thing and returns nothing, and honestly? iconic behavior 😌

---

💖 ARGUMENTS 💖

• test — The KUnit test context. yes bestie, the whole test rig lives in here 🧚

---

🦋 DESCRIPTION 🦋

okay so picture this 🙈 the bound component callback is out here doing its thing, and the vibe check says it should do three whole things:

1. find the connector whose audio instance matches the requested port 🔍
2. report it enabled (say it with your chest 💅)
3. copy the connector ELD 📋

that's it. that's the test. she finds the match, she says "yes queen you're enabled," and she copies that ELD over. periodt 🔥

💀 quick heads up bestie: dm_test_audio_component_get_eld_no_match(9) up there is the other one — this page is the matching connector version. don't mix them up, that would be a vibe check failure 🙈

and that's the page!! 🎀 source/version squished into the footer lives at ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so mark your calendars, she's from the future ⭐ bye bestie, go write some passing tests 💜🌸✨
