Getting 38.5 Mh/s UBIQ on Vega 56.

Pure open source..  rocm-opencl + sgminer-gm

pp_table being a bitch, so I'm OD'ing the mclk to where I want it, and setting the sclk to level 3.

# echo 17 > /sys/class/drm/card0/device/pp_mclk_od
# /opt/rocm/bin/rocm-smi --setsclk 3
# /opt/rocm/bin/rocm-smi --setmclk 3
# ./rocm-smi

Once I get the pp_table working right, I'll be able to lower my voltage.

So you're not using amdgpu-pro drivers?  Please could you share how you got OpenCL working in Linux? Sometime ago I've tried phoronix's guide using the hacked kernel and MESA + Clover + amdgpu stack with sgminer-gm but it didn't work.
