Clinfo not finding on Intel UHD Graphics 620 in WSL

[lr1729]

I installed with

add-apt-repository ppa:intel-opencl/intel-opencl
apt update
apt install intel-opencl-icd

On WSL 2 Ubuntu 18.04, however clinfo reports 0 platforms.

However, there is a /etc/OpenCL/vendors/intel.icd file. This is the output of LD_DEBUG=files clinfo

WSL 2

See microsoft/WSL#3789

You may check this lspci | grep VGA anyway.

[JacekDanecki]

I don't think it's supported. Besides lspci output can you also provide log from strace:

strace -s 255 -f clinfo

I have retried this dual booting into ubuntu, and it now is successfully detected.
