Not needed: dc will be automatically enabled on recent GPU

> amdgpu.vm_update_mode=0

Shouldn't be needed since it should be the default value. 

> amdgpu.dpm=-1

Not needed: this is the default value

> amdgpu.ppfeaturemask=0xffffffff

The only difference with the default value is that you're enabling Overdrive.
I'd suggest to keep the default parameter here.

> amdgpu.vm_fault_stop=2

I think this one isn't helpful (it's a debugging tool)

> amdgpu.vm_debug=1

This one can help.

> amdgpu.gpu_recovery=0

No opinion on this one :)
