Intel openCL HDR tone mapping problem in Synology - shoooot - 2024-08-28

When transcoding video using hardware acceleration in the Synology Docker, I am getting errors in tone mapping.
I understand there is an issue with Intel openCL support.
I would like to know if this issue has been resolved.
I'm using an N100 CPU.

The issue for Synology NASes is due to Synology still using an old Linux kernel (4.4) in most of their models. Intel deprecated OpenCL support for that kernel.

Check the version of the intel-opencl-icd package you are running. If the version is 22.### then it is too old. N100 support was added in version 23. If you are using an older distro, even as recent as Ubuntu 22.04, you will need to go to Intel's git and get a newer Intel Compute Runtime version that what Ubuntu's repo provides.

You just need the "intel-opencl-icd" package from Intel's git.

Sadly, I don't know much about the Synology system.
Can you tell me how to check the package version on a Synology system?
I do know that the model I have installed uses the 5.x version of the Linux kernel though. It is SA6400.

Can you explain how you're using a N100 CPU? Synology doesn't make any NAS units that come with that CPU model.

Please let me know if this is against community rules.

Does that allow you to run your own kernel? Or are you forced to use whatever kernel Synology may be using with their own hardware?

Open a command prompt and run "sudo uname -a".

I need to use Synology's kernel.
I don't know how to run any other kernel.

You need kernel 5.17 and newer for AlderLake CPUs/GPUs, including the N100.
