💅 dm_test_dp_r...cd_null_priv(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this page is about one tiny KUnit test that lives in the AMD display driver tests, and yes the title is literally abbreviated with dots in it, that's just how it is, no cap 🎀

🌸 NAME 🌸

dm_test_dp_read_dpcd_null_priv — the test that checks a DPCD read returns false when there's no connector 💀

✨ SYNOPSIS ✨

void dm_test_dp_read_dpcd_null_priv (struct kunit *test );

that's it, that's the whole signature, she's short and she knows it 🫶

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 💖 like, the little container the test framework hands you so the test knows where to report stuff. that's the whole argument, one (1) singular struct pointer, we love a minimalist queen 👑

👑 SEE ALSO 👑

okay so this is the part where the manpage gets feral and dumps the entire friend group on you 😭 these are all the sibling tests, and the kernel file they live in. i'm listing every single one because i would never do you dirty like that 💜

Kernel file 🌈

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

the whole squad 🧚

like… 143 entries bestie, she ate and left zero crumbs 🔥 go read the ones you care about, i'm not gonna gatekeep ✨

and that's the page!! 🎀 this gem ships from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so yeah, mildly time-travel-coded, lowkey iconic 💫 mwah, study well, drink water, and may all your DPCD reads return exactly what you expect 🦋💖
