From 6ced8c080921a2b21af93ff6665725f4b220641c Mon Sep 17 00:00:00 2001 From: Shirish S Date: Fri, 16 Nov 2018 06:50:28 +0000 Subject: [PATCH] Revert "drm/amd/powerplay: Enable/Disable NBPSTATE on On/OFF of UVD" This reverts commit dbd8299c32f6f413f6cfe322fe0308f3cfc577e8. Reason for revert: This patch sends msg PPSMC_MSG_DisableLowMemoryPstate(0x002e) in wrong of sequence to SMU which is before PPSMC_MSG_UVDPowerON (0x0008). This leads to SMU failing to service the request as it is dependent on UVD to be powered ON, since it accesses UVD registers. This msg should ideally be sent only when the UVD is about to decode a 4k video.
