Nvidia GeForce GTX 560 M not recognized as an OpenCL platform with Ubuntu HWE-5.15

Hi,

Before to update to Linux Mint 21, based on Ubuntu 22.04 LTS, I have tried 5.15.0-50 kernel with HWE. This was intended as a test of my hardware compatibility with the hardware stack of Ubuntu 22.04, before a possible update.

At a first glance, all seemed OK; nut I noticed that LibreOffice was unable to use OpenCL. A simple “clinfo” command confirmed this:

  $ clinfo
  Number of platforms 0

I went back from 5.15.0-50 kernel to 5.4.0-128 one. Now, “clinfo” output is:

 ICD loader properties
   ICD loader Name OpenCL ICD Loader
   ICD loader Vendor OCL Icd free software
   ICD loader Version 2.2.11
   ICD loader Profile OpenCL 2.1

And LibreOffice now accepts OpenCL.

Nothing else than the kernel has changed between the two “clinfo” commands.

Here is some more information on my system (“inxi” command outputs):

In both cases, installed graphics driver is “nvidia-driver-390”, 390.154-0ubuntu0.20.04.1.

NB: test done again with 5.15.0-56 kernel and 390.157 drivers with the same result:

 $ clinfo
  Number of platforms 0

while it still works with 5.4.0-135 kernel and 390.157 drivers.

Fermi based gpu, only supported up to cuda 8.

Hi,

I am not sure of what you says, since GTX 560 M works with Cuda 9.1.84 and kernel 5.4:
“Platform Version OpenCL 1.2 CUDA 9.1.84”

(read the second clinfo output)

And system change was limited to kernel, nothing related to Nvidia installation had changed (system stayed on a basis of Ubuntu 20.04 LTS; with kernel 5.15 it became equivalent to Ubuntu 20.04 LTS HWE, with hardware enhancement and the same hardware stack as Ubuntu 22.04 LTS).

F=Fermi=Cuda 8.
It won’t work with cuda 9.

Hi,

The clinfo output with 5.4 kernel shows it DOES work with Cuda 9.

MN

Sorry, I misread.
To make things clear:
Fermi does not work with cuda 9, but of course OpenCL will still work on the cuda 9 capable 390 driver.
Please check if the driver works and vidia-uvm is loaded.

Hi,
Thanks for your answer; how can I check nvidia-uvm is loaded? While I am running 5.4 kernel and OpenCL works, I have no process and no service with the name “nvidia-uvm”. (I have two processes with nvidia, “nvidia” and "nvidia-modeset).
Moreover, if nvidia-uvm is not automatically loaded (in my 5.15 kernel configuration), how can I manually load it?
The graphics driver 390.157 works with both kernels, including accelerated graphics OpenGL.

MN

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Hi,

Here is the log.
nvidia-bug-report.log.gz (121.1 KB)

I have noted that there is no nvidia-uvm in my dev directory.

I have tried to correct this with the following bash, from “Cuda Installation Guide for Linux”:

#!/bin/bash

/sbin/modprobe nvidia

if [ "$?" -eq 0 ]; then
  # Count the number of NVIDIA controllers found.
  NVDEVS=`lspci | grep -i NVIDIA`
  N3D=`echo "$NVDEVS" | grep "3D controller" | wc -l`
  NVGA=`echo "$NVDEVS" | grep "VGA compatible controller" | wc -l`

  N=`expr $N3D + $NVGA - 1`
  for i in `seq 0 $N`; do
    mknod -m 666 /dev/nvidia$i c 195 $i
  done

  mknod -m 666 /dev/nvidiactl c 195 255

else
  exit 1
fi

/sbin/modprobe nvidia-uvm

if [ "$?" -eq 0 ]; then
  # Find out the major device number used by the nvidia-uvm driver
  D=`grep nvidia-uvm /proc/devices | awk '{print $1}'`

  mknod -m 666 /dev/nvidia-uvm c $D 0
else
  exit 1
fi

However, I get the following error when I launch the bash, even with sudo:

modprobe: FATAL: Module nvidia-uvm not found in directory /lib/modules/5.15.0-56-generic

So, it seems something is missing.

My question now: how to get the missing module ?

Regards,

MN

That’s odd, according to the logs, the nvidia-uvm module was built and installed for both the 5.4 and 5.15 kernel.
Don’t know if a copy of it is still in /var/lib/dkms/nvidia/390.157/build/
BTW, you should rather remove “nomsi” from kernel cmdline.

Maybe just run
sudo depmod -a
to recreate the module database.

Hi,

  • In GRUB, “pci=nomsi,noaer” is here because of USB 3.0 hardware (Fresco Logic FL1000G USB 3.0 Host Controller).
  • I have an “nvidia-uvm.ko” in “/var/lib/dkms/nvidia/390.157/5.4.0-135-generic/x86_64/module”. Can I copy it somewhere to solve the problem?
  • “sudo depmod -a” didn’t solve the problem, reinstallation of “nvidia-driver-390” neither.

Hi,

I finally solved the problem that way:

sudo apt install linux-modules-nvidia-390-5.15.0-56-generic

where: “390” is the number of my Nvidia driver, and “5.15.0-56-generic” is the name of my kernel (output of “uname -r”).

This induced the installation of the following packages: “linux-modules-nvidia-390-5.15.0-56-generic”, “linux-objects-nvidia-390-5.15.0-56-generic”, “linux-signatures-nvidia-390-5.15.0-56-generic”.

And now, my clinfo with 5.15.0-56 kernel:
