💅 dm_test_crt...psr_su_skips(9) — Kernel API Manual ✨

okay so bestie, welcome to the dm_test_crt...psr_su_skips(9) page of the Kernel API Manual — yes the title's abbreviated with the dots, that's just how it's filed, don't come for me 🫶

🌸 NAME 🌸

dm_test_crtc_set_static_screen_optimze_psr_su_skips — literally a test for the PSR SU skips PSR event, no cap. (And yes, optimze is spelled like that in the actual symbol, so we're keeping it exactly as-is, iykyk 💅)

🦋 SYNOPSIS 🦋

void dm_test_crtc_set_static_screen_optimze_psr_su_skips (struct kunit
test );

that's the whole signature, she's cute, she's compact ✨

🎀 ARGUMENTS 🎀

  • test — the KUnit test context 💖 like, this is the lil test-world she's running inside of, that's it, that's the vibe

🌈 DESCRIPTION 🌈

okay so here's the tea 🍓: when self-refresh entry is allowed and the PSR version is DC_PSR_VERSION_SU_1, the function must update the replay event — but it skips the PSR event update. That's the whole bit. Replay event: updated ✅. PSR event: skipped 🙈. That's the behavior being tested, periodt.

👑 SEE ALSO 👑

Kernel file — she lives here, come visit:

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_crtc_test.c

and here's the whole friend group, all of them, not skipping a single one because I would never 😭💜

and that's the page!! 🧚 source/version is ./drivers/gpu/drm/amd/display/... and it's dated October 2026, still filed under dm_test_crt...psr_su_skips(9) — slay, go read the kernel file bestie, mwah 💋💖
