Source: linux Version: 4.5~rc7-1~exp1 Severity: wishlist Hi,
powerplay is the power management for the amdgpu driver. On top of the config switch this feature used to be hidden behind an additional kernel module parameter. As of v4.5 it looks like it's enabled per default for the families 'tonga' and 'fiji', but need to be enabled via the kernel cmdline for 'carrizo' and 'stoney', see [0]. Please enable CONFIG_DRM_AMD_POWERPLAY. Thanks, Andre [0] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/amd/amdgpu/amdgpu_powerplay.c?id=refs/tags/v4.5#n95
