Re: [PATCH 1/1] AMDGPU: Correctly initialize thermal controller for GPUs with Powerplay table v0 (e.g Hawaii)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Initialize thermal controller fields in the PowerPlay table for Hawaii
GPUs, so that fan speeds are reported.
