dm_test_cac..._unsupported(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

dm_test_cacp_caps_lcd_unsupported — literally the test that checks CACP is not supported on an LCD panel 💅

okay so real talk: this page lives in the Kernel API Manual, section 9, and the header up top gets its name all chopped down to dm_test_cac..._unsupported(9) because apparently even manpage titles have a character limit, iykyk 😭

✨ SYNOPSIS ✨

void dm_test_cacp_caps_lcd_unsupported (struct kunit *test );

🌸 ARGUMENTS 🌸

  • test — The KUnit test context 🫶 that's it, that's the whole argument list, she's low-maintenance

🦋 SEE ALSO 🦋

The kernel file that's doing all the heavy lifting here:

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

and bestie, the cross-reference list on this page is giving main character energy — like, sit down, hydrate, this is a long one 💀 Every one of these gets (9)'d, no cap:

the subconnector squad first:

find_first_crtc, she searches:

more set_panel_type (she came back for round two):

more CAC P caps, the sequel:

fill_stream, the whole saga 💫:

create_stream everything:

detect force on/off + sink stuff:

lazy register / destroy / disable:

atomic check trio:

and finally, the update_scaling finale 🎬:

ngl bestie, that cross-reference list is a lot — but every single one of those is exactly as written, so if you're grepping for one, it's in there 💖

and that's the page!! 🦋 it ships from ./drivers/gpu/drm/amd/display/... and it's dated October 2026, so like… future icon behaviour, periodt ✨💅🎀
