Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly.
