dm_test_cacp..._unsupported(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 dm_test_cacp..._unsupported 💅

okay bestie so this is a Kernel API Manual page, and yes the title is literally truncated with ... in it, that's not me being lazy, that's the actual page name: dm_test_cacp..._unsupported(9). We're starting strong. ✨

🎀 NAME 🎀

dm_test_cacp_caps_ip_3_1_6_unsupported — the test that checks CACP is unsupported on DCE 3.1.6. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

void dm_test_cacp_caps_ip_3_1_6_unsupported (struct kunit *test );

like, that's it. that's the function. void in, void out, no drama, no return value, we love a low-maintenance icon. 😌

🧚 ARGUMENTS 🧚

  • test — the KUnit test context 💖 this is the little container that KUnit hands your test so it can track what's going on. just pass it along, she knows what she's doing.

🔥 DESCRIPTION 🔥

so here's the tea, bestie: DCE 3.1.6 is explicitly excluded even though it is newer than 3.1.4. 🫶

read that again, because it's giving plot twist. newer usually means "gets the shiny new feature," right? nope. not here. 3.1.6 is newer than 3.1.4 and still gets the exclusion treatment, on purpose, explicitly. this test is the one making sure that "explicitly excluded" thing actually stays true and doesn't get quietly dropped in some refactor. no cap. 🔥

⚠️ lowkey important: the "explicitly excluded" part is doing a LOT of work in that sentence. it's not an accident of the version comparison, it's a deliberate carve-out. that's exactly the thing this test is guarding. 💅

and now, the main event, the whole entire friend group, in order, no one left behind: 👑

okay that's the whole page bestie, and like, the way this list just goes — iconic behavior, honestly. 238 entries and not one of them skipped. 😤💜 iykyk.

and for the cute little sign-off at the bottom: this one comes from ./drivers/gpu/drm/amd/display/... and it's dated October 2026, and of course it signs itself dm_test_cacp..._unsupported(9) because consistency is a lifestyle. 🎀✨ slay. bye bestie! 👑🦋
