nvidia-persistenced's Introduction

______________________________________________________________________________

NVIDIA-PERSISTENCED SOURCE DOCUMENTATION
______________________________________________________________________________

This document outlines the source code and build instructions for the NVIDIA
Persistence Daemon, nvidia-persistenced. Information on how to use 
nvidia-persistenced is available in the driver README and via the manpage that
is installed along with the driver or installed from this source package.

The daemon is controlled by an RPC interface that is generated by rpcgen. The
files have been pre-generated for this source package to remove any dependency
on rpcgen on the target system. The build otherwise only relies on the command
line utility m4 to generate the manpage documentation, aside from the standard
build tools.

To build nvidia-persistenced and its manpage, you can simply run:

    make

This will generate all output files within a system-specific subdirectory of
the '_out' directory.

To install nvidia-persistenced and its manpage, you can simply run:

    make install

There are also a few init files included in the source distribution that may
be used to start the NVIDIA Persistence Daemon on system startup. These files
are provided as examples and may not install correctly out of the box. Please
see init/README for more information.

nvidia-persistenced's Issues

Add IgnoreOnIsolate=true to the systemd unit

Consider adding IgnoreOnIsolate=true to the systemd unit. While this isn't entirely useful as operations such as "systemctl isolate rescue" would kill any user-space processing utilizing the GPU, this still creates parity with persistence mode since persistence mode is enabled while the kernel module is loaded and survives "systemctl isolate..." operations.

nvidia-persistenced for beta drivers

Hi,

It would be nice to have releases available for the beta drivers (https://developer.nvidia.com/vulkan-driver)

Thanks.

Release for 525.85.12

Hi,

I don't see a release for v525.85.12. Is there a reason why this version is not supported?

nvidia-persistenced.service doesn't start automatically on boot.

Hi, I work on AWS P3, Ubuntu 16.04, NVidia driver 410.79. My problem is that the service starts automatically only after some manual intervention / "touch" of the GPU (manual run of 'systemctl start nvidia-persistenced.service' or nvidia-smi). But the same configuration doesn't starts automatically on boot...
NVidia-persistence.service configuration file (placed in (/lib/systemd/system/nvidia-persistenced.service, configured with service enabling - I.e. relevant link is set from /etc/... to /lib/...) :
[Unit]
Description=NVIDIA Persistence Daemon
Wants=syslog.target
[Service]
Type=forking
Restart=always
ExecStart=/usr/bin/nvidia-persistenced --verbose -u nvidia-persistenced -g nvidia-persistenced
ExecStopPost=/bin/rm -rf /var/run/nvidia-persistenced
[Install]
WantedBy=multi-user.target

This is the output after reboot (without any manual intervention):
4:~$ systemctl status nvidia-persistenced.service
● nvidia-persistenced.service - NVIDIA Persistence Daemon
Loaded: loaded (/lib/systemd/system/nvidia-persistenced.service; enabled; vendor preset: enabled)

Mar 03 13:47:27 ip-10-10-1-174 systemd[1]: Stopped NVIDIA Persistence Daemon.

After running nvidia-smi from command line - the status is below (service started automatically):

My question:
Can I start the service automatically, without any prior manual intervention?

Doesn't work on RHEL-8 ppc64le

https://fedoraproject.org/wiki/Changes/SunRPCRemoval
If you guys can update the Daemon to work for RHEL-8 P9 as well!

nvidia-persistenced keeps it's username after remove

Hello.

in Ubuntu 13.04, when installing nvidia-persistenced, and removeing it agian.
it keeps the username "nvidia-persistenced-daemon" in the system and it doesn't remove it, this cause some problems when remastering the local system in some tools like Remastersys or Relinux.. because nvidia-persistenced uid is 999.

the fix is just to run this command automatically after package removal:
$ sudo userdel nvidia-persistenced

so, is there anyway to do this by default in nvidia-persistenced instead of doing it manually?

thanks.

Release for 440.82

A release is missing for the latest driver.
