💅 dm_test_get_plane_modifiers_gfx12 — from the Kernel API Manual ✨

okay bestie so this is a page out of the Kernel API Manual, section 9, and it's the whole rundown on dm_test_get_plane_modifiers_gfx12. it's short, it's sweet, and it's lowkey iconic 🎀

🌸 NAME 🌸

dm_test_get_plane_modifiers_gfx12 — the little function whose whole job is verifying GFX12 modifier list generation. that's it, that's the gig 💖

✨ SYNOPSIS ✨

void dm_test_get_plane_modifiers_gfx12 (struct kunit *test );

no return value, no drama. literally just vibes and verification 🦋

🫶 ARGUMENTS 🫶

  • test — the KUnit test context. it's the little test-holder that carries the state for this run, and yes, it's doing main character energy here 💅

🔥 DESCRIPTION 🔥

so what does it actually do? it verifies whether the GFX12 family dispatches to the GFX12 modifier builder — like, does the right code path get picked up — and it also checks that the whole thing produces a terminated list at the end. not me being obsessed with a properly terminated list 😭 it's giving "closure" fr fr.

that's the entire test: right builder gets dispatched ✅, list comes out terminated ✅, slay 💀✨

🧚 quick reminder bestie: this all lives under the display/amdgpu_dm test tree up there in the kernel file path — that's the home base, iykyk 💜
