Does Phoenixminer suppport AMD RX5700 (NAVI) under Linux?
Yes, but we haven't released our optimized kernels yet, as AMD Linux drivers are still not usable for ETH mining with Navi. The TLB problem was fixed on Windows with 19.9.1 but it is still present on Linux with the latest drivers. Hopefully AMD will release fixed Linux drivers soon.
Thank you for the update! One more question I have, when new drivers are available will it be possible to mix RX 5700 and RX 580 in one rig?
