[PATCH 6.6 324/396] Revert "drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays without PSR"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Harry Wentland <harry.wentland@xxxxxxx>

commit 78aca9ee5e012e130dbfbd7191bc2302b0cf3b37 upstream.

This causes flicker on a bunch of eDP panels. The info_packet code
also caused regressions on other OSes that we haven't' seen on Linux
yet, but that is likely due to the fact that we haven't had a chance
to test those environments on Linux.

We'll need to revisit this.

This reverts commit 202260f64519e591b5cd99626e441b6559f571a3.
