📦 version 7.3.1, in nixpkgs unstable

🎀 dm_test_fill_blending_global_alpha(9) 🎀

okay bestie, so you found yourself in the Kernel API Manual and the page you landed on is this little icon: dm_test_fill_blending_global_alpha(9). it's giving "niche but important" and honestly? she ate. let's get into it 💅

✨ NAME ✨

dm_test_fill_blending_global_alpha — literally verifying that global alpha gets converted down to 8 bits. that's the whole vibe check, no cap.

✨ SYNOPSIS ✨

void dm_test_fill_blending_global_alpha (struct kunit *test );

yes that's the exact signature, spaces and all, don't @ me 🫶

✨ ARGUMENTS ✨

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

✨ DESCRIPTION ✨

so what does she actually do? she verifies whether global alpha is enabled, and whether it gets converted from 16-bit to 8-bit. that's the entire mission statement. short, sweet, and absolutely doing her job correctly 🔥

no cap, that's the full description — the manpage is not hiding extra lore from you 🌸

✨ SEE ALSO ✨

first up, the Kernel file she lives in (exact path, bestie, copy it right):

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

and now the guest list — every single one of her test-function besties, in the order the manpage introduces them 🦋:

like, seventy-three icons in one friend group. the group chat is unhinged and we love her for it 😭💜

and that's the whole page, bestie — every flag, every name, every path, nothing skipped. this one came from the kernel source at ./drivers/gpu/drm/amd/display/... and she's dated October 2026. go forth and verify that alpha conversion, queen 👑🦋💖
