Subject: [PATCH 1/3] Revert "drm/amd/powerply: fix power reading on Fiji"
Date: Wed, 11 Apr 2018 14:31:45 +0800	[thread overview]
Message-ID: <1523428307-7969-1-git-send-email-Rex.Zhu@amd.com> (raw)

we don't have limit of [50ms, 4sec] sampling period.
smu calculate average gpu power in real time.
we can read average gpu power through smu message or
read special register.

This reverts commit 462d8dcc9fec0d89f1ff6a1f93f1d4f670878c71.
