dm_test_dis...th_sso_delay(9)

✨ NAME ✨

Okay bestie, so this page is from the Kernel API Manual (yes, that's the vibe — kernel API, main character energy) and it's all about one very specific little test function:

dm_test_dispatch_next_event_opt_idle_with_sso_delay — and what it's testing, fr fr, is the case where sso_delay_ns > 0, the SSO timer is in play, and there's no IMMEDIATE 💅

Like, it's that exact scenario. No cap.

🌸 SYNOPSIS 🌸

void dm_test_dispatch_next_event_opt_idle_with_sso_delay (struct kunit
*test );

That's the whole signature, iconically short 🎀

---

🦋 ARGUMENTS 🦋

• test — the KUnit test context. That's it. That's the one (1) argument, and honestly she's carrying the whole test on her shoulders 🫶

Lowkey important: this page is a test description, so nothing here is gonna blow up your system — but keep every name spelled exactly right when you go looking, because kernel symbol names do not accept typos and they do not accept vibes 🙈

And that's a wrap, bestie! 🎀 This absolute gem comes from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — future icon behaviour, honestly 👑 See you in the next test, muah 💜
