🌸 dm_test_fil...alpha_format(9) 💅

okay bestie so this is a page from the Kernel API Manual and it's literally all about dm_test_fill_blending_premulti_alpha_format. yes that's a mouthful, we know, we've been pronouncing it wrong too 🫶 it's a KUnit test thing and honestly it's giving "small function, big responsibility" energy ✨

✨ NAME ✨

dm_test_fill_blending_premulti_alpha_format — the way this one verifies the premultiplied alpha path. yes. that's the whole job. iconic honestly 🎀

🦋 SYNOPSIS 🦋

void dm_test_fill_blending_premulti_alpha_format (struct kunit *test );

🍓 ARGUMENTS 🍓

  • test — the KUnit test context, aka the little backstage pass that makes the whole test happen. hand it over and you're good 🎟️

💖 DESCRIPTION 💖

so what does it DO. it verifies whether premultiplied mode actually enables per-pixel alpha for ARGB8888. that's it. that's the vibe check. no cap, that's the entire description and we're obsessed with the efficiency 💅

bestie note: this page isn't gonna hand you extra lore — what you see is what the docs give you, and we're keeping it 100% accurate 🌸

👑 SEE ALSO 👑

the "Kernel file" you wanna peek at is:

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

and now, the moment you've all been waiting for — the FULL friend group, all 73 of them, no skipping, no "tl;dr", we're listing every single one because they're all main characters 💀✨

and that's the page!! mwah 😘 one tiny test, one huge SEE ALSO section, and a whole lot of GPU plane lore. stay hydrated, read your kernel source, and remember: premultiplied alpha is that girl 💜

sign-off time bestie 🎀 — this little beauty comes from ./drivers/gpu/drm/amd/display/... and it's dated October 2026. yes, October 2026. future-forward documentation, we love to see it ⭐🌈
