dm_test_crt..._none_commit(9)

💅 dm_test_crt..._none_commit(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in the big-kid kernel docs now, and this one is a whole little KUnit test with main character energy 🎀

---

🌸 NAME 🌸

dm_test_crtc_set_crc_source_none_commit — the test that sets a CRC source while a commit is still pending, and honestly? it slays 🫶

---

🦋 SYNOPSIS 🦋

void dm_test_crtc_set_crc_source_none_commit (struct kunit *test );

---

💖 ARGUMENTS 💖

• test — the KUnit test context, aka the little backpack this test carries its whole world in 🎒✨

---

👑 DESCRIPTION 👑

So here's the vibe check 👇 this one verifies that a pending CRTC commit is acquired and then waited on — and ngl, in this case it's already completed, so the wait just returns immediately, no suspense, no cliffhanger, we love a zero-effort wait 😌 — and then it gets released during cleanup. Gotta return what you borrow, periodt 💅

And the configuration? Still deferred, bestie. Why? Because no stream is attached. That's it, that's the reason. No stream, no config, no cap 🧚

fr fr, if you only remember one thing: pending commit gets acquired, waited on (instantly, bless), released in cleanup, and config stays deferred because there's no stream. that's the whole tea ☕💀

and that's a wrap, bestie — this page came from the source path ./drivers/gpu/drm/amd/display/... and it's dated October 2026, so like… future era energy 🦋⭐ love that for us. bye pookie, go read the other crc tests 💜🎀
