✨ dm_test_get...11_64k_first(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this little page is about dm_test_get...11_64k_first(9) and honestly? it's a whole vibe check for GFX11 small-pipe ordering. buckle up 🎀

🌸 NAME 🌸

dm_test_get_plane_modifiers_gfx11_64k_first — this one verifies the GFX11 small-pipe order, no cap 🔥

🦋 SYNOPSIS 🦋

void dm_test_get_plane_modifiers_gfx11_64k_first (struct kunit *test );

🎀 ARGUMENTS 🎀

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

👑 DESCRIPTION 👑

so here's the tea ☕ this test verifies whether GFX11 modifier generation reads GB_ADDR_CONFIG through the RLC register callback — like, actually goes through the callback, not around it, iykyk — and it also verifies that it prefers 64K_R_X when the pipe count is 16 or lower. periodt. 🌈

literally that's the whole test. small pipe count, big 64K_R_X energy. 💅✨
