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
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?
