 Posted: Fri Sep 20, 2024 7:38 pm Post subject: [Solved] nvidia-drivers and suspend to RAM |
 |
|
Hi,
my habit using sys-power/hibernate-script to suspend my main machine to RAM after a while in order to not let the computer run without reason, cannot be kept up, if I do not change some configuration, but I don't know exactly how
When issuing suspend to ram, the machine immediately returns back to power on and dmesg tells me the following about the reason why:
| Code: |
NVRM: GPU 0000:06:00.0: PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please refer to the 'Configuring Power Management Support' section in the driver README.
nvidia 0000:06:00.0: PM: pci_pm_suspend(): nvidia_isr_kthread_bh+0x560/0x810 [nvidia] returns -5
nvidia 0000:06:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -5
nvidia 0000:06:00.0: PM: failed to suspend: error -5
PM: Some devices failed to suspend, or early wake event detected
|
As far as I understand the README by nvidia, I've been lucky that s2ram has been working for so long, and now I have to somehow make suspend work via elogind, as I don't use systemd. Is there any documentation for that?
Kind regards.

The recent nvidia-drivers revbumps (-r1) had a one-time warning that you may have missed:
| Code: | if [[ ${REPLACING_VERSIONS##* } ]] &&
ver_test ${REPLACING_VERSIONS##* } -lt 560.35.03-r1 # may get repeated
then
elog
elog "For suspend/sleep, 'NVreg_PreserveVideoMemoryAllocations=1' is now default"
elog "with this version of ${PN}. This is recommended (or required) by"
elog "major DEs especially with wayland but, *if* experience regressions with"
elog "suspend, try reverting to =0 in '${EROOT}/etc/modprobe.d/nvidia.conf'."
elog
elog "May notably be an issue when using neither systemd nor elogind to suspend."
elog
elog "Also, the systemd suspend/hibernate/resume services are now enabled by"
elog "default, and for openrc+elogind a similar hook has been installed."
fi |
So you if you want to return to the previous behaviour and everything was fine "for you", then you can edit nvidia.conf to return to =0 then reboot.
As for elogind, `loginctl suspend` should work in theory (same as systemd). Not something I ever tried and most users been testing this using their DE's suspend/sleep button instead.
Alternatively, not familiar with hibernate-script, but in theory anything can be used if you can just make them call /usr/bin/nvidia-sleep.sh (takes suspend, hibernate, or resume as arguments) to do the same thing that elogind/systemd would be doing. I imagine calling sleep.sh resume may be difficult without some kind of "on resume" hooks w/ a daemon though.
Switching to =1 would be esp. needed if you ever plan to use wayland as resume otherwise (often) resullts in graphical corruption. Both Gnome and Plasma also recommend that this is set, which is why this is the new default. May matter less for simple setups. |

Thanks for your quick answer. Indeed, I must have overlooked the new default in /etc/modprobe.d/nvidia.conf
I've set PreserveVideoMemoryAllocations back to 0 for now and will probably switch to the eloginctl method in the future, as the elogind-daemon is running anyway, although i use awesome wm. |

I had the same problem although using elogind and loginctl suspend/hibernate (openrc and X11).
I had to set NVreg_PreserveVideoMemoryAllocations=0 to get a display back when waking up from hibernation, but entering suspend/hibernate and waking up from it are much slower than before. I hope a future update will fix the problem, but I won't know when to go back to NVreg_PreserveVideoMemoryAllocations=1. |

The wake up process is quite slow with NVreg_PreserveVideoMemoryAllocations=0
Well, one has to try from time to time to set it to 1 or so it seems in order to be able to try out wayland, for example. The latter also requires "options nvidia-drm modeset=0" which completely freezes my system on boot. |

I found that I can save 5sec on suspend/hibernate with InhibitDelayMaxSec=0
| Quote: | | Well, one has to try from time to time to set it to 1 |
Yes of course.
| Quote: | | or so it seems in order to be able to try out wayland, for example. |
I have 3 monitors and the configuration with wayland was always a disaster each time I tried. I prefer not.
| Quote: | | The latter also requires "options nvidia-drm modeset=0" which completely freezes my system on boot. |
Good to know. I'll try it with NVreg_PreserveVideoMemoryAllocations=1 to see.
Thanks. |

There could be something strange going on but... everything here sounds.. backward?
1. NVreg_PreserveVideoMemoryAllocations=1 (not =0), can be the one that is slower because (afaik) it saves+reload memory allocations to disk, and in the event of a slow device on /var/tmp it can be noticeable. Note that the path can be changed in nvidia.conf (to a faster device), tmpfs is also a potential option given enough space (not that this makes much sense for hibernation given tmpfs' ram will be saved to disk).
2. The latter requires modeset=0...? Does that refer to wayland? Because wayland *requires* modeset=1, nvidia-drivers also sets =1 by default with USE=wayland. Afaik there are not a whole lot of things that don't work with =1 nowadays, and there is little reason to use =0. The nvidia upstream default of =0 with USE=-wayland is only kept not to cause surprises given it's what it has been for decades and because NVIDIA docs still call it "experimental".. but at this point about all major distros default to =1 for wayland. It'd probably make sense to do modeset=1 regardles of USE=wayland like Allocations=1 at this point. |

| Sorry for the confusion. I wanted to say that "options nvidia-drm modeset=1" needs to be set in order to get wayland to work according to the nvidia.conf file in /etc/modprobe.d/. But that freezes my system. I don't know why. |

I see, no real idea what could cause this either. I know =1 can cause problems with SLI and Reverse Prime but you'd know that already given it's in nvidia.conf, so probably something else. |

Finally, I figured out how to have both
| Code: | | options nvidia-drm modeset=1 |
and
| Code: | | NVreg_PreserveVideoMemoryAllocations=1 |
enabled in /etc/modprobe.d/nvidia.conf and a working suspend mechanism on my system. Two steps seem to have been necessary.
1. switching to loginctl suspend and
2. putting the kernel in an initramfs including the nvidia modules (nvidia, nvidia_drm, nvidia_modeset). (I used the dracut tool for that, but there are other methods too.)
The initramfs presumbaly prevents the boot process from freezing, because it loads the nvidia modules at an ealier stage. |

When suspending with systemctl suspend, the system doesn't enter suspend state. Getting the same errors you mentioned in OP:
| Code: | $ journalctl -b

Any suggestion? I've never been able to suspend with NVreg_PreserveVideoMemoryAllocations=1 so far.
Edit: Silly me, forgot to enable nvidia-{resume,suspend,hibernate}.service units again. Will report back if that makes any difference. |

OK, works fine now after enabling nvidia-{resume,suspend,hibernate}.service units again. I had to disable
| Code: | | xss-lock --transfer-sleep-lock -- physlock & |
in my AwesomeWM autostart script, else when suspending physlock would lock my session and the system wouldn't enter suspend state until I enter my username password again. Then, the machine would resume on TTY2 for some reason, I'd had to switch back to TTY1.
I'll have to test with 6.6 kernel and NVIDIA 550 though.
Edit: Not working with 6.6 kernel and NVIDIA 535. Still getting a black screen after resuming. Will try 6.6 + NVIDIA 550.
After this, I've been able to suspend/resume four times in a row just fine, with one exception. If I suspend while having mpv playing a video (in paused state before suspending, of course) and also using hardware video decoding with in ~/.config/mpv/mpv.conf, then the machine won't enter suspend state. I'm getting the following errors:

Suspend/resume works if removing hwdec=auto. Maybe I should create a separate topic for this? |
