I am trying to use a Radeon RX 5700XT via OpenCL with kernel 5.3.0 (I have also tried kernel 5.3.18) on Ubuntu 18.04. I have noticed that this combination is much slower than expected. I'm trying to find out why, and how to fix it. If I'm in the wrong place to ask, would you be able to point me in the right direction? If this is a known outstanding problem, a reference to a bug or something else that would let me dig into it would be great. Thanks Josh Fuhs |
