GPU powerdown when not in use seems to only be supported on intel processors so far. I recently got a laptop with AMD Ryzen 4600H and GTX 1650 Ti and power management is a mess. I use optimus-manager and when it’s in integrated mode cat /sys/bus/pci/drivers/nvidia/0000\:01\:00.0/power_state
reports D3cold
but in hybrid mode it is D0
.
So it seems that powering down GPU is possible, although cat /proc/driver/nvidia/gpus/0000:01:00.0/power
says:
Runtime D3 status: Not supported
Video Memory: Active
GPU Hardware Support:
Video Memory Self Refresh: Supported
Video Memory Off: Supported
Power Limits:
Default: N/A milliwatts
GPU Boost: N/A milliwatts
So i’m wondering if ryzen processors will ever be properly supported, or maybe something is wrong with my config?
