Nvidia GeForce GTX 560 M not recognized as an OpenCL platform with 5.15.0-50 kernel

[Michel NALLINO]

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:

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):

I have the same issue.
OpenCL was working before upgrading from Linux Mint 20.3 to 21.

Now clinfo reports: Number of platforms 0

No OpenCL in Darktable or LibreOffice.

Hi,

I found a workaround to this problem. I solved the problem by installing new packages:
"sudo apt install linux-modules-nvidia-390-5.15.0-56-generic"
where:
- "390" is the main version of the Nvidia driver (390.157);
- "5.15.0-56-generic" is the name of the kernel ("uname -r" output).

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”.

LibreOffice now detects OpenCL; and clinfo output with 5.15.0-56 kernel shows GTX 560 M is detected as an OpenCL platform:
"clinfo

Thx Micheal NALLINO,

your workaround solved my issue.

I'm running:
Linux Mint 21.1 Cinnamon
Kernel: 5.15.0.16-generic
NVIDIA GeForce GTX 550 Ti (GF116)

and opencl is now recognized.

I had the same issue on my Asus U36S laptop
and is now solved too.

Laptop:
Linux Mint 21.1 Cinnamon
Kernel: 5.15.0.16-generic
NVIDIA GeForce GT 520M

Thx
