How to enabling OpenCL with intel Arc 770 in Ubuntu

[TimWe]

I installed the

install "intel-opencl-icd" in ubuntu 22.04 and "clinfo"- output is following:

NULL platform behavior
clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...) Intel(R) OpenCL HD Graphics
clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, ...) Success [INTEL]
clCreateContext(NULL, ...) [default] Success [INTEL]
clCreateContext(NULL, ...) [other] Success [INTEL]
clCreateContextFromType(NULL, CL_DEVICE_TYPE_DEFAULT) Success (1)
Platform Name Intel(R) OpenCL HD Graphics
Device Name Intel(R) Graphics [0x5690]
clCreateContextFromType(NULL, CL_DEVICE_TYPE_CPU) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_GPU) Success (1)
Platform Name Intel(R) OpenCL HD Graphics
Device Name Intel(R) Graphics [0x5690]
clCreateContextFromType(NULL, CL_DEVICE_TYPE_ACCELERATOR) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_CUSTOM) No devices found in platform
clCreateContextFromType(NULL, CL_DEVICE_TYPE_ALL) Success (1)
Platform Name Intel(R) OpenCL HD Graphics
Device Name Intel(R) Graphics [0x5690]

ICD loader properties
ICD loader Name OpenCL ICD Loader
ICD loader Vendor OCL Icd free software
ICD loader Version 2.2.14
ICD loader Profile OpenCL 3.0

I think OpenCL is active? But what means "No devices fund in platform"?

Ineed OpenCL especially for "Darktable"

"darktable-cltest"  -output is following:

darktable founds a "libOpenCL" but whats the meaning of wrong platformsetup? How can I setup right?

Hello TimWe,

Thank you for your patience. We have reviewed your concern, but we need to gather more information to better understand and identify the root cause. Could you please provide the following details:

1. Can you share the exact link to the Darktable app you are using?

2. Provide the Intel® System Support Utility Logs of your computer. This will help us check your system configuration in depth. You can check our Help Guide for the Intel® System Support Utility, look for Linux, and follow the steps to obtain the logs. Once you have the logs, kindly attach them to this thread.

3. Has this setup ever worked before, or is this the first time you are setting it up?

Best regards,
