Ethminer.exe quits running or hangs when trying to recognize Intel Iris Xe Graphics as an OpenCL device

[tjtjtjtj-tw]

Describe the bug
I have a handheld game-console-like computer, One Xplayer 1S. ( http://www.onexplayer.com/ )
It is equipped with Intel(R) Iris(R) Xe Graphics.
(GPU: Tiger Lake GT2. Shaders: 96 Unified. Memory Type: DDR4, Bandwidth: 64GB/s. )
(Driver version: 30.0.101.1069 DCH / Win10 64. Driver date: 2021/11/02)

I saw that the latest version of ethminer.exe supports Intel graphic cards. ( libethash-cl/CLMiner.cpp )
BTW, somebody was successful running it. (Driver version 25.20.100.6793 can be still found, but Iris Xe card cannot use that driver. ( https://www.reddit.com/r/EtherMining/comments/lv21va/pool_mining_ethereum_with_intel_integrated/ )
Therefore I give it a try.

**===**Condition 1:
"HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors" have no registry inside.
**===**Phenomenon1:
GPU-Z shows it supports OpenCL full and OpenCL 3.0 NEO.
"ethminer.exe -G --list-devices" ==> Error: No usable mining devices found

**===**Condition 2:
"HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors" have registries named "C:\Windows\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_6c531da99dfd5830\Intel_OpenCL_ICD64.dll" and "C:\Windows\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_6c531da99dfd5830\Intel_OpenCL_ICD32.dll" respectively.
**===**Phenomenon2:
GPU-Z shows it DOESN'T support OpenCL.
"ethminer.exe -G --list-devices" ==> Program hangs after showing "ethminer 0.1x.x... (version) Build: windows/release/msvc".
However, the system idle rate in task manager is above 98%.

**===**Condition 3:
"HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors" have registries named "C:\Windows\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_6c531da99dfd5830\opencl-clang64.dll" and "C:\Windows\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_6c531da99dfd5830\opencl-clang32.dll" respectively.
**===**Phenomenon3:
GPU-Z shows it supports OpenCL full and OpenCL 3.0 NEO.
"ethminer.exe -G --list-devices" ==> Error: No usable mining devices found

Can anyone help?

(tested version: 0.18.0-rc.0, 0.18.0, and 0.19.0-alpha.0)

To Reproduce
Steps to reproduce the behavior:

1. Turn on computer and boot up Windows 10.
2. I added registry keys with different DWORD names.
3. Reboot computer.
4. Execute "ethminer -G --list-devices" or "ethminer --list-devices"
   5-ending-situation1. Program quits after showing:
   Error: No usable mining devices found
   5-ending-situation2. Program hangs after showing:
   ethminer 0.1x.x... (version)
   Build: windows/release/msvc

Screenshots (Optional)

Environment (please complete the following information):

• Operating System: Windows 10
• Hardware [e.g. Intel(R) Iris(R) Xe Graphics
• Ethminer Version 0.18.0-rc.0, 0.18.0, and 0.19.0-alpha.0
• Ethminer options used: --list-devices

Additional context
I am sure that those ethminers.exe of said 3 version works fine with my nVidia 2060 and 3070 notebook graphics.
I just want to let my Intel Xe graphics work as well.
