From 274baf695b08d34230253a792fcb3d6790040ab6 Mon Sep 17 00:00:00 2001 From: Gil Fine Date: Thu, 10 Aug 2023 23:18:23 +0300 Subject: [PATCH] thunderbolt: Add DP IN added last in the head of the list of DP resources If DP IN on device router exist, position it at the beginning of the DP resources list, so that it is used before DP IN on host router. This way external GPU will be prioritized when pairing DP IN and DP OUT for DisplayPort tunnel setup.
