💀 ngl that's a lot of cross-references, but every single one is here, no cap. Nothing skipped, nothing merged. iykyk 🫶

okay that's the whole page bestie, ily, go write some tests ✨🌸

this came straight out of ./drivers/gpu/drm/amd/display/..., dated October 2026 — and yeah, the page name is still dm_test_irq...valid_source(9) in case you were wondering 🎀 periodt 💅
