With this kernel 5.8.0-35-generic #37~lp1907212+2 nvidia gpu is successfully powered down, and idle power consumption was normal at 5-6 watt.
$ cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status suspended $ cat /sys/bus/pci/devices/0000:01:00.1/power/control auto On dmesg output there are a lot more `snd_hda_intel 0000:01:00.1: can't change power state from D3cold to D0 (config space inaccessible)` complaints. I also rebooted at nvidia performance mode, everything is normal but `0000:01:00.1/power/runtime_status` is again suspended. I don't know if it is supposed to be like this but with 5.8.0-31-generic when booting with nvidia performance mode, `0000:01:00.1/power/runtime_status` is active. ** Attachment added: "dmesg_5.8.0-35~lp1907212+2.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907212/+attachment/5443236/+files/dmesg_5.8.0-35~lp1907212+2.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907212 Title: Power consumption regression after upgrade to 20.10 5.8.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907212/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
