From a056ddce9b15a117949e59ad44bea5b3d12f17b5 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Fri, 16 Aug 2019 17:11:46 +0800 Subject: [PATCH] drm/amd/powerplay: correct SW smu11 thermal range settings Problems with current settings: 1. The min value was overrided to 0 on Vega20 & Navi10. While the expected should be -273.15 C. 2. The thermal min/max threshold was output in wrong unit on Navi10 & Arcturus. As TEMP_RANGE_MIN/MAX is already in millicelsius. And "*1000" in smu_v11_0_start_thermal_control makes the output wrongly.
