[PATCH 07/51] drm/amd/powerplay: add basic powerplay framework
Alex Deucher
alexdeucher at gmail.com
Wed Nov 11 22:17:57 PST 2015
From: Rex Zhu <Rex.Zhu at amd.com>
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.
