From dab848908f44b3468050c18315987238d056d9e3 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 24 Jan 2018 17:57:19 -0500 Subject: [PATCH 3290/4131] drm/amdgpu/pm: rework the hwmon visibility settings Previously we just always exposed everything for asics supported by powerplay. Make it a bit more fine grained. In practice this shouldn't change anything.
