💅 dm_test_dp_..._passthrough(9) — Kernel API Manual energy

okay so bestie, welcome to the Kernel API Manual page for dm_test_dp_..._passthrough(9) — yes that's the short little nickname the header gives it, the real one is down in NAME. this is a KUnit test thing and honestly? she's niche, she's specific, she's doing her little job in the AMD display test suite. let's get into it 🎀

✨ NAME ✨

dm_test_dp_write_dsc_enable_mst_disable_passthrough — literally the Test MST disable passthrough write test. that's the whole vibe. no cap, that's what she does 🔥

🌸 SYNOPSIS 🌸

void dm_test_dp_write_dsc_enable_mst_disable_passthrough (struct kunit *test );

that's it. that's the whole signature. no return value (it's void, she gives nothing back and she's at peace with that 💅), just one parameter ✨

🦋 ARGUMENTS 🦋

  • test — The KUnit test context. this is the little ✨context✨ object KUnit hands you so the test can actually do test things. you don't invent it, you don't free it, it's just there, being a context 🫶
for real fr fr, that's the only argument. she's lowkey a minimalist 👑

🌈 SEE ALSO 🌈

okay so this part is LONG, bestie. the manual really said "here's the entire test family tree, no skips, no crumbs" and honestly? iconic. first up, the kernel file where all this lives:

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

and now the whole friend group, in the exact order the page gives them 💖

look at her. the sibling-tier test list is immaculate. she's got friends in EDID land, MST land, DSC land, MCCS land — the whole extended universe 🔥 if you ever wanted to know who else lives in amdgpu_dm_helpers_test.c, boom, there's your roster 💜

and that's the page, bestie!! sign-off time 🎀 this little cutie came out of ./drivers/gpu/drm/amd/display/... in October 2026 — that's the source and the date, right there, so you know exactly which era of the kernel you're looking at. k-thanks-bye, go read the other 142 pages 🌸✨🫶
