From e91974e16db3a8820e076f2c82187c387b5d8626 Mon Sep 17 00:00:00 2001 From: Yongqiang Sun Date: Wed, 9 Dec 2020 16:56:51 -0500 Subject: [PATCH] drm/amd/display: change SMU repsonse timeout to 2s. [Why] there is some garbage showing up during reboot test. Reason: SMU might handle display driver msg defered and driver will send next msg to SMU after 10ms timeout, once SMU FW handle previous msg, parameters are changed to next one, which result in a wrong value be programmed. [How] Extend timeout to 2s so SMU will have enough time to handle driver msg.
