💅 dm_test_crtc_duplicate_state_copies_fields — a Kernel API Manual moment ✨

okay so bestie, we're in the Kernel API Manual today and this page is literally about dm_test_crtc_duplicate_state_copies_fields — a KUnit test that just wants to make sure your duplicated CRTC state doesn't ghost its DM fields. no cap, it's a whole vibe check for state copying 💖

---

✨ NAME ✨

dm_test_crtc_duplicate_state_copies_fields — the test where duplicated state has to carry the DM fields, periodt 🎀

---

🦋 SYNOPSIS 🦋

void dm_test_crtc_duplicate_state_copies_fields(struct kunit *test);

---

🌸 ARGUMENTS 🌸

• test — the KUnit test context, aka the little group-chat thread the test runs inside 🫶

---

💅 DESCRIPTION 💅

So here's the lore 👑: when you duplicate a CRTC state without a stream, you have to end up with a brand-new state that carries over the DM-specific fields from the current state. that's it, that's the whole test. new state, old DM fields, no losing anything in the handoff. slay 💖

bestie pls note: the source path gets abbreviated in the footer, so it's ./drivers/gpu/drm/amd/display/... — don't come for me, that's just how the page renders it 🙈

and that's the whole page!! source lives under ./drivers/gpu/drm/amd/display/..., dated October 2026, and it's page dm_test_crtc...opies_fields(9) of the Kernel API Manual. mwah, go run your tests 💜🌸✨
