From 95ccc155081be9cea95202d290fe06637f47c8de Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 18 Jul 2019 15:25:04 -0500 Subject: [PATCH] drm/amdgpu/smu: move fan rpm query into the asic specific code On vega20, there is an SMU message to query it. On navi, it's fetched from the metrics table.
