RE: [PATCH 2/2] drm/amd/powerplay: add arcturus_is_dpm_running function for arcturus

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

 



Please set FEATURE_DPM_PREFETCHER_MASK | FEATURE_DPM_GFXCLK_MASK only. For now, only these two are enabled on arcturus.

With that fixed, the patch is reviewed-by: Evan Quan <evan.quan@xxxxxxx>
