PRIME doesn't work with NVIDIA [SOLVED]

I am trying to auto disable my NVIDIA 1650 (Turing) when no needed to win some battery time since I have also integrated AMD video.
Following this manual https://wiki.archlinux.org/title/PRIME#NVIDIA in the end I receive that runtime_suspended_time is always 0 (which means something goes wrong).
Despite I did it carefully nothing worked. I tried nvidia-prime-rtd3pm just be sure. Also no effect.

What am I missing?
The strange is a process name with Xorg.
Would appreciate any help.

Re: PRIME doesn't work with NVIDIA [SOLVED]

Please use [code][/code] tags. Edit your post in this regard.

The strange is a process name with Xorg.

That's likley xwayland and "normal" - the display server is assigned to the GPU even if you're running on the IGP, speaking of which: do you have better results w/ plasma on X11?
Also nvidia-smi will wake the device for sure, only check the runtime_status

Have you confirmed that NVreg_DynamicPowerManagement is used by the module?

Also nb. 

For Turing generation cards with Intel Coffee Lake or above CPUs as well as some Ryzen CPUs like the 5800H, it is possible to fully power down the GPU when not in use

Re: PRIME doesn't work with NVIDIA [SOLVED]

do you have better results w/ plasma on X11

Wayland feels smoother and better overall.

Have you confirmed that NVreg_DynamicPowerManagement is used by the module?

systool -vm nvidia
Module = "nvidia"

  Attributes:
    coresize            = "10022912"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "33"
    srcversion          = "BABF5253924D36C48E7D170"
    taint               = "OE"
    uevent              = <store method only>
    version             = "550.54.14"

  Sections:
modinfo nvidia | grep NVreg_DynamicPowerManagement
parm:           NVreg_DynamicPowerManagement:int
parm:           NVreg_DynamicPowerManagementVideoMemoryThreshold:int

Which means the option was not applied.

I meant for RTD3.

Why?

The wiki wrote:

Modinfo can't tell you that but apparently nvidia still doesn't export the parameters to sysfs, check your journal - if you enable the serivces but forgot/failed to enable the parameters, the driver will complain about that.
If that's the case, chances are you've nvidia in the initramfs and forgot to regenerate that?

Yea, that's good news, I read it. Since you point it twice, you know the direct way how to do that?

I did that after 

mkinitcpio -P

Re: PRIME doesn't work with NVIDIA [SOLVED]

Yea, that's good news, I read it. Since you point it twice, you know the direct way how to do that?

That point is that this is supported for SOME, but NOT necessarily for EVERY ryzen chip (incl. possibly yours)

W/ "nvidia.NVreg_DynamicPowerManagement=0x02" in the kernel commandline, the parameter is however set.
Make sure the udev rule actually applied.

cat /sys/bus/pci/devices/0000:01:00.0/power/control
cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status

And disable nvidia-powerd, it only works w/ ampere chips - https://download.nvidia.com/XFree86/Lin … boost.html

Edit: forgot to ask over the ryzen situation, do you remove the usb devices?

It was disabled.
But anyway I did 

systemctl stop nvidia-powerd.service
systemctl disable nvidia-powerd.service

Edit: forgot to ask over the ryzen situation, do you remove the usb devices?

Since the docs says its not requider for kernel >= 5.5 I skipped initially.
But I did that now

# Remove NVIDIA USB xHCI Host Controller devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c0330", ATTR{remove}="1"

# Remove NVIDIA USB Type-C UCSI devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c8000", ATTR{remove}="1"

# Remove NVIDIA Audio devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x040300", ATTR{remove}="1"

nothing changed

You want that to say "auto", please post your entire udev rule.

Somehow there was not a conf file in /etc/udev. I created it again.
Now I managed to get 'auto'.

Re: PRIME doesn't work with NVIDIA [SOLVED]

Well, I did it. I guess it was deleted when I removed nvidia-prime-rtd3pm package.

Any discernible impact on the concerned situation?

No. It didn't effect anything.

Can you please confirm this is correct for my case?

/etc/mkinitcpio.conf
MODULES=(nvidia nvidia_modeset nvidia_drm)

Re: PRIME doesn't work with NVIDIA [SOLVED]

You don't need the modules in the initramfs for this to work.

"cat /proc/driver/nvidia/gpus/0000:01:00.0/power" still says "not supported"?

I should set MODULES=() ?

"cat /proc/driver/nvidia/gpus/0000:01:00.0/power" still says "not supported"?

Yes.

cat /proc/driver/nvidia/gpus/0000:01:00.0/power
Runtime D3 status:          Not supported
Video Memory:               Active

Re: PRIME doesn't work with NVIDIA [SOLVED]

Based on this https://forums.developer.nvidia.com/t/n … poznianski my CPU should support RD3. I have Ryzen 5500U.

Re: PRIME doesn't work with NVIDIA [SOLVED]

It's fine to add the modules to the initramfs and will prevent the GUI from starting "too early", but it's not relevant to this topc.

That thread wrote:

there’s no official docs from nvidia regarding D3 on ryzen, it seems it only works on ryzen 5xxx models

Which is speculative and inconclusive (as is the arch wiki) because "there’s no official docs from nvidia regarding D3 on ryzen" - you can also flat-out ask there, "hey, nvidia - is my CPU supported and why is there no official list"
All indication so far is that it's not - you could test against a driver regression (older nvidia drivers - 535xx, 545xx a 550xx all had their hiccups. nb. that older dkms packages will not compile against linux 6.8, you'd have to patch them or test the LTS kernel) or wait for future releases.

Edit: "inconclusive" as is does not state "on all 5xxxx models"

Re: PRIME doesn't work with NVIDIA [SOLVED]

To pile onto this, the wiki mentions "some Ryzen CPUs like the 5800H" which is a https://en.wikipedia.org/wiki/Zen_3 while you've a 5500U https://en.wikipedia.org/wiki/Zen_2 what might be a significant difference here (and the way hardware is labeled by amd, intel and nvidia these days should be punishable by public slapping or something like that)

Re: PRIME doesn't work with NVIDIA [SOLVED]

Today I did

cat /sys/bus/pci/devices/0000:01:00.0/power/control

and it shows 'on' again, instead of 'auto'. I dunno why. Despite the conf files are in place this time. How to debug?

Re: PRIME doesn't work with NVIDIA [SOLVED]

You asked me about USB. I created such file 

# Remove NVIDIA USB xHCI Host Controller devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c0330", ATTR{remove}="1"

# Remove NVIDIA USB Type-C UCSI devices, if present
ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c8000", ATTR{remove}="1"

# Remove NVIDIA Audio devices, if present

Re: PRIME doesn't work with NVIDIA [SOLVED]

/etc/udev/rules.d/80-nvidia-pm.rules looks like https://wiki.archlinux.org/title/PRIME#NVIDIA ?
What if you remove the unbinding parts?
Do you use anything like optimus-manager,  bbswitch etc et pp.?
