💅 dm_test_crtc..._source_dprx(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — you're looking at the page for dm_test_crtc..._source_dprx, and honestly? it's a little name that goes hard. let's get into it 🎀

---

🌸 NAME 🌸

dm_test_crtc_configure_crc_source_dprx — the test that checks the DPRX configure path. that's the whole vibe, no cap 🦋

---

🫶 SYNOPSIS 🫶

void dm_test_crtc_configure_crc_source_dprx (struct kunit *test );

---

✨ ARGUMENTS ✨

• test — the KUnit test context. it's literally the main character of this function's world 💜

---

🔥 DESCRIPTION 🔥

so what does this thing actually do? it verifies that a DPRX source can be configured with an empty DC resource state, which is the non-CRTC path — and that path only updates dither/dynamic expansion. so yeah, it's giving "slim little code path, still gets its own dedicated test" energy and we love that for it 💀🫶

ngl this is a unit test page, so the drama is contained. it tests one specific thing and it tests it well. periodt.
