dm_test_crtc..._no_sr_entry(9)

🎀 NAME 🎀

dm_test_crtc_set_static_screen_optimze_no_sr_entry — bestie, this is the KUnit test that checks the early return when SR entry is not allowed ✨ (and yes, the function name is spelled optimze, that's not a typo on my end, that's just how it lives 💅). Oh and hi, welcome to the Kernel API Manual page for dm_test_crtc..._no_sr_entry(9) 🫶

---

✨ SYNOPSIS ✨

void dm_test_crtc_set_static_screen_optimze_no_sr_entry (struct kunit
*test );

That's it. One argument, zero drama 💖

---

🦋 ARGUMENTS 🦋

• test — the KUnit test context 🧚 that's the whole vibe, it just needs to be passed in so the test framework knows what's up

---

💜 DESCRIPTION 💜

Okay so picture this 🌸: when self-refresh entry is not allowed, the function has to return immediately — like, no detours, no lingering, no "wait let me just…" 😭 — and it must not touch replay or PSR events at all. Not even a little. Not even a peek 👀

And the important part: it does that regardless of the requested SSO state. Whatever SSO state you asked for, doesn't matter, the early return ate and left no crumbs 💅 periodt.

lowkey the whole point of this test is proving that early return actually early-returns 🙈
