From a7d53dbbc70a81d5781da7fc905b656f41ad2381 Mon Sep 17 00:00:00 2001 From: Casey Bowman Date: Wed, 10 Feb 2021 11:20:41 -0800 Subject: platform/x86: intel_scu_ipc: Increase virtual timeout from 3 to 5 seconds Increasing the virtual timeout time to account for scenarios that may require more time, like DisplayPort Multi-Stream Transport (DP MST), where the disconnect time can be extended longer than usual. The recommended timeout range is 5-10 seconds, of which we will take the lower bound.
