Re: OpenCL Doesn't Recognize RX6700 XT in Ubuntu 20

Hi all,
Anyone managed to run RX6700 XT in ubuntu? Which ubuntu version, kernel, and amd driver? Do you enable legacy or rocr or both when installing amd driver? So far I have ubuntu 20.4.03 with its latest kernel, I think 5.11 and latest amd driver with both legacy and rocr enabled, but they don't work.
regards

Right now i have a RX6700 XT running ok on a test rig under PM 5.8c, Ubuntu 20.04.3 LTS 5.11.0-37-generic with AMDGPUPRO 21.30 which is OpenCL driver version: 21.30-1290604-rocr. Only clkernel 0 works tho and it isnt ideal due to high stale shares and multiGPU may not work due to limitations imposed by AMD in ROCR ( Happy to be wrong,  theory is nvidiea nobbled mining rigs with LHR and AMD did single GPU restriction in Rocr instead)

Main rig currently has 7 x RX6800XT under Manjero but with older driver made using PKGBUILD workaround (for multi gpu support) all singing sweet with clkernel 1 under PM 5.8c

Info on Manjero setup can be found on link below. (take note i dont get a lot of time to play with this so this solution might have been improved since)
