Subject: [PATCH] AMDGPU: Correctly initialize thermal controller for GPUs with Powerplay table v0 (e.g Hawaii)
Date: Sun, 5 Apr 2020 22:22:50 +0530	[thread overview]
Message-ID: <CAGPDPzCHs0ty0rxs=QN7xmHhuDfftdO17P81-s=L=J5e_14vNw@mail.gmail.com> (raw)

This is required for the AMDGPU driver to report fan speed for Hawaii
GPUs (otherwise the fan speed is just reported as 0)
