🎀 ARGUMENTS 🎀

  • test — the KUnit test context. that's it, that's the entire arg list, no notes 💅

🦋 SEE ALSO 🦋

first up, the kernel file this test lives in:

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

okay so now the part where this page literally does the most: it links every single sibling test in that file. not a subset. not a sample. all of them. no cap, here we go 🫶

the subconnector-type girlies:

content type besties:

adjust colour depth (yes it's spelled colour, iconic):

output color space, the whole spectrum 🌈:

color depth conversions & lookups:

connector type mapping, the plug-shape directory 🔌:

duplicate mode checks:

encoder crtc masks 1 through 6 (she counted, bestie):

aspect ratios:

crtc timing copying & deciding:

funcs_reset edp abm + misc:

set_property squad (setting things is her roman empire):

get_property squad (and now we're getting them back):

refresh + freesync video mode:

cacp caps, round one:

panel type detection:

subconnector updating:

fbc init:

mst detection:

find first crtc:

more panel type (samsung era):

cacp caps, round two:

fill_stream (the glow-up pipeline):

create_stream:

detection era:

misc hardware dealings:

atomic checks:

cec & edid & link caps:

encoder & native mode:

common modes & ddc & freesync modes:

i2c & vsdb & displayid:

mode valid:

more cec, this time set + s3:

validate stream:

update after detect:

update scaling, the grand finale 💫:

okay that was a lot of links and every single one of them is here, bestie. nothing skipped, nothing merged, nothing "cleaned up" 💀

and that's the whole page, periodt 🎀 she lives in ./drivers/gpu/drm/amd/display/..., she's dated October 2026, and she answers to the page name dm_test_fun...ets_defaults(9) in the Kernel API Manual. go forth and slay your tests 👑💜
