OpenCL not working properly with RX 5500 XT

Hello.

I'm trying to install the lastest AMD driver v21.10 for Ubuntu 20.04 LTS (server edition). Full support was introduced for Ubuntu 20.04 in this version of driver, but it does not work properly in my case.

In newer version of Linux kernel was introduced amdgpu driver support, so I'm trying to install driver with next commands and it installs without any errors:

 

./amdgpu-install -y --opencl=legacy,pal --headless --no-dkms
sudo usermod -aG video $LOGNAME
sudo usermod -aG render $LOGNAME

 

After reboot I'm trying to run clinfo command and it shows that I don't have any devices:

 

$ /opt/amdgpu-pro/bin/clinfo 
Number of platforms:				 1
  Platform Profile:				 FULL_PROFILE
  Platform Version:				 OpenCL 2.1 AMD-APP (3224.4)
  Platform Name:				 AMD Accelerated Parallel Processing
  Platform Vendor:				 Advanced Micro Devices, Inc.
  Platform Extensions:				 cl_khr_icd cl_amd_event_callback cl_amd_offline_devices 
  Platform Name:				 AMD Accelerated Parallel Processing
Number of devices:				 0

 

However lshw command shows that I have RX 5500 XT GPU in my system:

 

$ sudo lshw -c display
  *-display                 
       description: VGA compatible controller

I've also tried to install the driver with ./amdgpu-pro-install --opencl=legacy,pal --headless command, but in that case it deletes integrated kernel module, rebuilds dkms module and does not help.

Please help to solve this issue.

Ubuntu version: 20.04.2 LTS

AMD driver version: 21.10 (https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-21-10)

Re: OpenCL not working properly with RX 5500 XT

Maybe @dipak can move this to the Developer's Forum OPENCL if appropriate.

Or you can open a thread at Developer's Forum New Users to get whitelisted to post at OpenCL Forum from here: https://community.amd.com/t5/newcomers-start-here/bd-p/newcomer-forum

Re: OpenCL not working properly with RX 5500 XT

Hi @nanom1t ,

Thank you for reporting this. I've moved the post to the OpenCL forum.  Also I've whitelisted you for the AMD Devgurus community.

There are two OpenCL implementations available with the latest AMDGPU-Pro:

ROCr: Provides support for Vega 10 and newer hardware.
Legacy: Provides support for hardware older than Vega 10.

In previous releases, the “PAL” implementation was used for Vega 10 and newer cards, but now this has been replaced by the ROCr. So, please modify the command accordingly. 

For example: ./amdgpu-pro-install -y --opencl=rocr,legacy --headless

For the detailed instructions,  please find the latest installation guide by extracting the downloaded archive, and opening /doc/index.html in your browser.

 

Thanks.
