dm_test_crt...store_replay(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_crt...store_replay(9) — like, the Kernel API Manual edition 🎀

okay bestie, buckle up, because this is a kernel API manual page and I'm about to make it make sense ✨

🌸 NAME 🌸

dm_test_crtc_enable_vblank_ips_restore_replay — the test that checks IPS restore works when the self-refresh support comes from replay instead of PSR. yes, that's a whole mouthful, i know, i know 😭

🦋 SYNOPSIS 🦋

void dm_test_crtc_enable_vblank_ips_restore_replay (struct kunit *test
);

like, that's the whole signature. one arg. she's lowkey minimal 💅

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. that's it, that's the arg. it's giving "just here to hold the test together" energy 🫶

✨ DESCRIPTION ✨

okay so this test is literally the sibling of dm_test_crtc_enable_vblank_ips_restore — same vibes, except the self-refresh support gets established through replay instead of PSR. no cap 🔥

here's the tea: the PSR version is unsupported in this scenario, so the sr_supported computation has to fall all the way through to pr->config.replay_supported. the way that fallthrough is the whole point of this test, iykyk 🧚

and through all of it, the enable path still calls drm_crtc_vblank_restore and then completes. iconic behavior, honestly 👑

💖 SEE ALSO 💖

the kernel file this lives in, bestie:

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

and here's the whole squad — every last one of them, no skipping, i promised 🙈:

fr fr that's every single one. i counted. twice. because i love you 🫶💜

and that's the page, babe 💖 this one came from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so like, from the future, iconic honestly ⭐🌈👑
