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.

No pro drivers. No Mesa or Clover needed... Dont need GUI, no OpenGL, etc.

Code:

# ldd sgminer | grep libOpenCL
libOpenCL.so.1 => /usr/lib/x86_64-linux-gnu/libOpenCL.so.1 (0x00007f208a3d3000)

I have the m-bab 4.12.14+ kernel installed also, but was having issues detecting my GPUs, even though lspci showed them, amdkfd didnt see them.. and because of that clinfo would segfault. I tried rx470, rx570, and rx vega, and no luck. I sort of wanted to play with the 4.12.14+ with the DC/DAL patches for a full mesa opengl wayland, but I can wait for v4.15 for all that. Its not necessary for mining.
