[PATCH 11/12] drm/amd/display: Fix handling duplicate planes on one stream
Hersen Wu
hersenxs.wu at amd.com
Wed Nov 1 20:08:31 UTC 2023
From: Sung Joon Kim <sungkim at amd.com>
[why]
DML2 does not handle the case when we have
a single stream sourcing 2 or more planes
that are duplicates of one another. To properly
handle this scenario, pipe index to plane index
mapping is used to decide which plane is being
processed and programmed.
[how]
Create static array of pipe index to plane index map.
Populate the array properly and use in appropriate places.
