From eb6791939b3a50d7c764e43951da40cb5f8ead11 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 2 Dec 2015 17:46:21 -0500 Subject: [PATCH 0040/1110] drm/amd/powerplay: add basic powerplay framework amdgpu_pp_ip_funcs is introduced to handle the two code paths, the legacy one and the new powerplay implementation. CONFIG_DRM_AMD_POWERPLAY kernel configuration option is introduced for the powerplay component. v4: squash in fixes v3: register debugfs file when powerplay module enable v2: add amdgpu_ucode_init_bo in hw init when amdgpu_powerplay enable.
