From 9d455cb89dc576f752beebcadc823511882fb321 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Mon, 5 Dec 2022 15:33:31 +0800 Subject: [PATCH] drm/amd/pm: update SMU13.0.0 reported maximum shader clock commit 7a18e089eff02f17eaee49fc18641f5d16a8284b upstream. Update the reported maximum shader clock to the value which can be guarded to be achieved on all cards. This is to align with Window setting.
