From b099752b3b40fd84fa47fd874bf0f068cc99931f Mon Sep 17 00:00:00 2001 From: Mikita Lipski Date: Fri, 23 Aug 2019 13:26:24 -0400 Subject: [PATCH] drm/amd/display: Rebuild mapped resources after pipe split [ Upstream commit 387596ef2859c37d564ce15abddbc9063a132e2c ] [why] The issue is specific for linux, as on timings such as 8K@60 or 4K@144 DSC should be working in combination with ODM Combine in order to ensure that we can run those timings. The validation for those timings was passing, but when pipe split was happening second pipe wasn't being programmed. [how] Rebuild mapped resources if we split stream for ODM.
