From cae50a43b931c6d70c7e16e1128af10398d8635a Mon Sep 17 00:00:00 2001 From: Eric Yang Date: Fri, 24 Aug 2018 16:54:14 -0400 Subject: [PATCH] drm/amd/display: use link type to decide stream enc acquisition [Why] Virtual sink is used when set mode happens on a disconnected display to allow the mode set to proceed. This did not work with MST because the logic for acquiring stream encoder uses stream signal to determine the special handling is required, and stream signal is virtual instead of DP in this case. [How] Use link type to decide instead.
