Weird OpenCL error ....

[w3333]

Hello, sorry to bother you. Not sure if that is even Katago's problem or something else. Have been using kata under Linux for years using OpenCL with an AMD GPU (RX570). Recently I switched to a RX6770XT, and after some troubles managed to install the AMD drivers for it for OpenCL support. However, some strange things happen that didn't happen before.

Here's the output Kata gives when I try to tune it:

Never seen that error before. But I suspect it has something to do with a line that clinfo is giving me (right under "CL_PROGRAM_BUILD_LOG"):

Maybe you have a clue.

Yeah, you might be running into a problem with drivers. I see the word "Mesa" appear in your info - that "Mesa" drivers have been found to be buggy for general purpose OpenCL usage by users in the past. Does this thread help? https://bbs.archlinux.org/viewtopic.php?pid=1895516#p1895516

Thanks. Seems like it. The only reason I tried the mesa-opencl-icd lib is cause an admin (on the mint forum) suggested that. Without it, my clinfo output doesn't even see the GPU as opencl device... but anyway, that's not your problem. Just thought I ask here, maybe the kata output would be a clue. Frankly I'm out of ideas. It used to work pretty well. Not sure what caused the problems, maybe a switch to a newer GPU (but not really, old GPU has same problems), maybe switching to Mint 21 (based on Ubuntu 22.04).... just can't get it to work anymore and even skilled people like the admins and devs on the Mint forum can't help... hm.

Only thing you might know: do you yourself use or know of people using AMD GPUs like the RX 6700 XT, or something from that generation, successfully with Linux/Ubuntu/Mint and Katago? I mean, this has to work somehow somewhere...

use AMD-Rocm instead of mesa which is currently known to be broken
