dm_test_fil...nconstrained(9)

🌸 NAME 🌸

dm_test_fill_gfx9_plane_attributes_dcc_rbplus_unconstrained — Verify block mode. This is the Kernel API Manual page for it, bestie, and it's iconic in a deeply specific kernel-test way. 💅

✨ SYNOPSIS ✨

void dm_test_fill_gfx9_plane_attributes_dcc_rbplus_unconstrained (struct
kunit *test );

🎀 ARGUMENTS 🎀

• test — KUnit test context. Yep, that's the KUnit test context right there — the little context package the test gets passed. 🫶

🦋 DESCRIPTION 🦋

Okay so the actual assignment is a vibe check: verify if a GFX10-RBPLUS modifier without independent block bits selects the unconstrained block mode. That's the whole mission. No independent block bits? Then it should lock in unconstrained block mode, and this test verifies exactly that. Periodt. ✨
