💅 dm_test_crtc_set_static_screen_optimze_sr_entry_psr(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual — this page is all about one very specific little KUnit test, and honestly? it's giving "narrow but iconic". let's get into it 🫶

🌸 NAME 🌸

dm_test_crtc_set_static_screen_optimze_sr_entry_psr — a test that pokes at the SSO toggle and checks that it drives PSR. yes queen, toggle it. 💅

(and yes, optimze is spelled exactly like that — not me, not a typo of mine, we're keeping it, periodt.)

✨ SYNOPSIS ✨

void dm_test_crtc_set_static_screen_optimze_sr_entry_psr (struct kunit
*test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. that's the little bubble of a world this test lives inside, and it's the only thing you hand it. 🌈

🦋 DESCRIPTION 🦋

so here's the vibe check 🧚:

when self-refresh entry is allowed and the PSR version is below DC_PSR_VERSION_SU_1, this function has to run both the replay event updates and the PSR event updates. like, both of them. no skipping, no picking favorites. 💖

and because the link in this test has no replay/PSR feature enabled, both of those event helpers just short-circuit safely — they bounce right off, no drama, no crash, we love a safe exit. 😌

the test also exercises both SSO states, which is the whole point: that's what gives us coverage of the set_vsync_event computation. both states, every time, because that's how we get the full picture. 👑
