[PATCH 6.2 218/242] drm/amd/display: Lowering min Z8 residency time

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Leo Chen <sancchen@xxxxxxx>

[ Upstream commit d893f39320e1248d1c97fde0d6e51e5ea008a76b ]

[Why & How]
Per HW team request, we're lowering the minimum Z8
residency time to 2000us. This enables Z8 support for additional
modes we were previously blocking like 2k>60hz
