Nvidia Power Management

Old setup

On Turing GPUs, the following is required in /etc/modprobe.d/nvidia.conf:

options nvidia "NVreg_EnableGpuFirmware=0"

/etc/modprobe.d/nvidia-pm.conf:

options nvidia "NVreg_DynamicPowerManagement=0x02"

New setup

IMPORTANT

D3 sleep on Turing cards is not possible with nvidia-open. Need to downgrade to nvidia-580xx
