dm_test_fill..._rbplus_128b(9)

📦 version 7.3.1, in nixpkgs unstable

✨ dm_test_fill..._rbplus_128b ✨

Okay bestie, so the full government name here is dm_test_fill_gfx9_plane_attributes_dcc_rbplus_128b, and it lives in section 9 of the Kernel API Manual — aka it's a kernel thing, not a "type man ls" thing. Buckle up, this one's a tiny little unit test but the SEE ALSO list is giving main character energy 🎀

🌸 NAME 🌸

dm_test_fill_gfx9_plane_attributes_dcc_rbplus_128b — literally just verifying 128B block mode. That's it. That's the whole lore. 💅

🦋 SYNOPSIS 🦋

void dm_test_fill_gfx9_plane_attributes_dcc_rbplus_128b (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — your KUnit test context. The lil' buddy that carries the test state around. You hand it over, it does its thing. 🫶

💖 DESCRIPTION 💖

So the whole vibe check here: this test verifies if a GFX10-RBPLUS modifier that has only the 128B independent block bit set actually selects the 128B block mode. That's the entire quest. No cap. 🔥

Like, one bit. One modifier. One thing to check. Iconic minimalism honestly. ✨

🌈 SEE ALSO 🌈

Oh girl. Okay. Strap in. This page does not do "a few related pages", it does the entire extended family reunion. 👑

Also worth shouting out: the kernel file this lives in is ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_plane_test.c — that's home base 🏠

Yeah. Seventy-three besties. I counted so you don't have to. 🍓

Lowkey a whole friend group in here, and every single one of them is a (9) kernel API page. Bring snacks. 🧚

Mwah 💜 that's the whole page! Sourced from ./drivers/gpu/drm/amd/display/... and dated October 2026 — so like, future girl summer. Go forth and verify that one single 128B bit, bestie. Slay. ✨👑
