dm_test_cacp...supported_ip(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

okay so this is dm_test_cacp_caps_unsupported_ip — the manpage for it lives in the Kernel API Manual (yes, the whole thing is kernel API documentation, we're being fancy today) — and it's literally just: Test CACP disabled on old DCE IP ✨

🎀 SYNOPSIS

void dm_test_cacp_caps_unsupported_ip (struct kunit *test );

🦋 ARGUMENTS

  • test — the KUnit test context 💖 that's it, that's the whole argument list, she's low maintenance.

🌸 DESCRIPTION

so here's the tea 🍵 — a DCE IP version below 3.1.4 does not support CACP, which means cacp_supported has to stay false, no cap, no exceptions. and bestie, that's regardless of signal or panel type 👑 — it doesn't matter how cute the signal is or what kind of panel shows up, old IP simply doesn't get CACP. periodt.

🌈 SEE ALSO

the kernel file for this one lives right here 🫶:

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

and because this test does not roll alone, here's her whole friend group (in the original order, every single one, no gatekeeping 💜):

and that's the whole page, bestie, you ate that 💅✨ source is ./drivers/gpu/drm/amd/display/..., dated October 2026 — this page is dm_test_cacp...supported_ip(9) and she said what she said 🎀🦋💖
