dm_test_get...iers_gfx10_3(9)
π dm_test_get...iers_gfx10_3(9) β Kernel API Manual, but make it bestie-friendly π
okay so technically this page is titled dm_test_get...iers_gfx10_3(9) bc the terminal truncates it (rude), but the actual function living its best life in here is dm_test_get_plane_modifiers_gfx10_3. and yes it's from the Kernel API Manual. let's get into it β¨
πΈ NAME πΈ
dm_test_get_plane_modifiers_gfx10_3 β literally just verifying the GFX10.3 modifier list generation. that's the whole vibe check. π
π¦ SYNOPSIS π¦
void dm_test_get_plane_modifiers_gfx10_3 (struct kunit *test );
π ARGUMENTS π
testβ the KUnit test context. it's the lil' passport this test carries around everywhere, no cap π«Ά
β¨ DESCRIPTION β¨
so what does it actually do? it verifies whether a 10.3+ NV family device dispatches to the GFX10.3 modifier builder and produces a terminated list. that's it, that's the whole flex. it's giving "one job and she does it" energy π and lowkey the terminated list part matters β a list with no terminator is a list that never ends and we don't do infinity loops in this house π
β SEE ALSO β

like, that's a whole squad. every single one tagged (9) like it's their area code ππ₯
and that's the page!! big sign-off energy: this one comes from the source path ./drivers/gpu/drm/amd/display/... and it's dated October 2026, and it goes out under the name dm_test_get...iers_gfx10_3(9) one more time because the header said so π« periodt π«Άβ¨
