GPU performance degrades after suspend

Hello everyone,

I am using bumblebee on my Nvidia Optimus laptop (Intel integrated + Nvidia dedicated cards). Whenever I put my system in suspension state (that is suspend to ram, hibernation works fine), running applications with my dedicated card through optirun stops working fine, since I get a huge performance degradation. By huge I mean that a game can go from running smoothly at 60FPS to falling back to 5FPS. I can replicate this every time I suspend to ram and resume my system. Rebooting the system fixes this until I suspend again.

I have been able to test this issue in many different games and applications, so this seems to be nothing application-related.

EDIT: I should also mention that I can consistently replicate this with all suspend methods (systemctl suspend, s2ram from uswsusp and even writing directly to /sys/power/state)

I have read the nvidia troubleshooting page, which seems to describe my issue (https://wiki.archlinux.org/index.php/NV … om_suspend). However, the suggested fix didn't work. I added the following file in /etc/modprobe.d/nvidia.conf to no avail:

options nvidia NVreg_RegisterForACPIEvents=1 NVreg_EnableMSI=1

Maybe this fix is specific to the normal nvidia driver usage, and bumblebee ignores the kernel module options in modprobe.d, could that be the problem? Is there a way to specify these options on bumblebee?

Or maybe I'm looking at the wrong place. Any tips to further debug this?

EDIT: There are a couple more "interesting" symptoms related to this issue. On one hand, this laptop has another issue where it will get stuck in some kind of loop on shutdown and never power off completely. Oddly enough, if I suspend and resume my system, getting the bad GPU performance I describe, shutdown works fine. Since all of this is related to ACPI, I also felt I should include these ACPI error messages that I'm getting during boot:

Re: GPU performance degrades after suspend

Thanks for your reply,

I had forgotten to mention that I read that wiki page and already have acpi and acpi_call installed. So that doesn't seem to be the issue.

Re: GPU performance degrades after suspend

That is supposed to fix the card not activating after suspension. My card is re-activated, but performs poorly. It's not the same issue. Nevertheless, I've tried it and it didn't work.

Also, no offense. I realize it's common to have posters who haven't read the wiki, but I can assure I've read the wiki pages on Nividia, Optimus and Bumblebee and the most common issues and troubleshooting before asking this.

Thanks

Re: GPU performance degrades after suspend

Sorry (but yes, referring to the wiki is usually a solution ;-)

Is the nvidia module loaded when going S3 (and is that relevant)?

If you haven't yet, ensure you're indeed using the GPU (optirun glxinfo) and then have a look at nvidia-smi (also post the output to record your actual GPU and driver version)
Notably have a look at performance and power settings and whether they adapt on load.

Next see whether a GPU reset helps (nvidia-smi -r)

Lastly, restart the X11 server and ensure the nvidia module gets unloaded at some point.

Re: GPU performance degrades after suspend

Thanks for your reply!

Is there a way I can run lsmod to check that after issuing a suspend command? My laptop has a hardware LED that turns red when the GPU is active, and I can confirm it turns red whenever I issue a suspend command, but I cannot confirm that the nvidia module is being loaded by the kernel.

If you haven't yet, ensure you're indeed using the GPU (optirun glxinfo) and then have a look at nvidia-smi (also post the output to record your actual GPU and driver version)

I can confirm the card works both after and before suspend (optirun glxinfo works, and also does optirun nvidia-smi). This is the output from glxinfo. There are no differences before and after suspend:

And this is the output from nvidia-smi, after suspending.

The first notable thing I could observe here is that the PID of the Xorg process keeps changing on each invocation of nvidia-smi (EDIT: That is normal, it's just how optirun works, spawning a new Xorg server at each invocation). The second, is that the card usage goes up to roughly 23% after suspend, when normally it is at 0%. However, running glxgears has a similar impact in the usage % before and after suspend. So, for example, if usually my load is at 0% and glxgears takes 60% GPU usage, after suspend, the value will be the 23% plus that 60%.

Next see whether a GPU reset helps (nvidia-smi -r)
Lastly, restart the X11 server and ensure the nvidia module gets unloaded at some point.

Using nvidia-smi -r doesn't seem to work, since the card is apparently being used by bumblebeed

$ optirun nvidia-smi -i 0 -r 
Unable to reset this GPU because it's being used by some other process (e.g. CUDA application, graphics application like X server, monitoring application like other instance of nvidia-smi). Please first kill all processes using this GPU and all compute applications running in the system (even when they are running on other GPUs) and then try to reset the GPU again.
Failed to reset Gpus.

However, if I stop the bumblebeed service and try this without optirun, the card is successfully reset. Then, without starting bumblebee, nvidia-smi shows 0% usage again. However, when I start the bumblebeed service again, and run optirun nvidia-smi, usage goes back up to 23%.

Restarting the X server with the bumblebee daemon active doesn't seem to help either.

EDIT: I also discovered the --no-xorg flag in optirun, which loads the nvidia module but doesn't create the separate Xorg server to render things into. That allows me to run "nvidia-smi -r" without stopping bumblebee, but the outcome is still the same. However, one additional thing I've noticed is that the usage when running "optirun --no-xorg nvidia-smi" is 0%. So we can confirm that the 24% usage comes from the Xorg server spawned by bumblebee.

EDIT2: I was looking at the dmesg output. Nothing catched my eye, but this is the relevant part of dmesg when launching a command through optirun:

pci 0000:01:00.0: Refused to change power state, currently in D0

The "Refused to change power state" and ACPI warnings looked promising at first, but after googling it it seems that they are both common messages and they actually happen even if the performance problem is not present. The other relevant (?) thing is that the dmesg output is identical before and after suspension.

EDIT3: More findings, it seems that after going into S4 (hibernation) and back the performance problem goes away. I thought that might be relevant.

This is all I have for now, any ideas?
