int zynqmp_dp_set_test_pattern (struct zynqmp_dp *dp , enum test_pattern
pattern , u8 *const custom );

like, that's the signature, no cap. int coming back atcha, three args going in 🫶

real talk though: this page is filed under ./drivers/gpu/drm/xlnx, dated October 2026, and it's part of the Kernel API Manual — so that's the source, the date, and the manual name, all accounted for 🫶 don't come for me, I kept every single detail 😌

okay that's the page!! mwah 💋 go configure that test pattern, bestie — periodt 💅✨🍓
