Using Memory DPM level 0! hello, there is the same problem in my dell Inspirion 5547. my output of `dmesg --levle=err,warn ` like this: > [ 5175.824105] amdgpu: [powerplay] VI should always have 2 performance levels > [ 5181.060603] amdgpu: [powerplay] can't get the mac of 5 > [ 5181.061744] amdgpu: [powerplay] VBIOS did not find boot engine clock value > > in dependency table. Using Memory DPM level 0! > [ 5186.704831] amdgpu: [powerplay] VI should always have 2 performance levels > [ 5191.861423] amdgpu: [powerplay] can't get the mac of 5 > [ 5191.862585] amdgpu: [powerplay] VBIOS did not find boot engine clock value > in dependency table. Using Memory DPM level 0! > [ 5196.872216] amdgpu: [powerplay] VI should always have 2 performance levels and my previous kernel version is 4.10-11-1-ARCH, now, I changed my kernel to 4.11.0-rc8-g5a7ad1146caa. however, the bug isn't solved. And I also checked the kernel code of drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c, this file's bug has been fixed since the bug#185681. however, my kernel also has the error of powerplay. so annoying. can you have any suggestion for me to solve this problem?
