dm_test_fil...om_modifiers(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for dm_test_fill_gfx9_plane_attributes_from_modifiers(9). This function is here to Verify basic GFX9 linear modifier path. That’s the assignment, and it ate. 💅

✨ SYNOPSIS ✨

the signature is right here, no cap:

void dm_test_fill_gfx9_plane_attributes_from_modifiers (struct kunit
*test );

🫶 ARGUMENTS 🫶

• test — the KUnit test context, bestie. That’s it. That’s the whole argument list. 🫶

🎀 DESCRIPTION 🎀

This test checks whether GFX9 linear modifier handling keeps DCC disabled — yes, the vibe is “is DCC staying off?” and the function is literally built to verify that. No extra plot twists. 🦋
