CLInfo reports error, AMD GPU on Ubuntu

[RichGit101]

Requesting help to fix this issue with CLInfo. In brief, GPU mining is not working, CPU mining is working smoothly, traced back to compile logs.No errors reported in Make but CLInfo reports error.

Basic information

• Type of the CPU. Intel Pentium G4560 3.50GHz Socket 1151 3MB
• Type of the GPU (if you try to miner with the GPU). Sapphire AMD Radeon RX 570 4GB NITRO+

Compile issues

• Which OS do you use? 4.15.0-23-generic #25-Ubuntu SMP - Fully Patched

  add all commands you used and the full compile output here clinfo reported error Compiling was smooth and normal but ended up with only CPU miner. 1) Checked AMD SDK - OK (please check below in log section) 2) Checked AMD GPU PRO Drivers - OK (please check below in log section) 3) Tried to compile with different options

All were successful. could complete compile and run. Could join pool. But only CPU and not GPU mining works.

run cmake -LA . in the build folder and add the output here worked

Issue with the execution

• Do you compiled the miner by our own? yes run ./xmr-stak --version-long and add the output here Version: xmr-stak/2.4.5/b3f79de/master/lin/cpu/aeon-cryptonight-monero/0

Stability issue

• Is the CPU or GPU overclocked? No
• Is the Main memory of the CPU or GPU undervolted? No

I don't think MESA works. You need the legacy driver I believe.

Uninstall everything mesa, reinstall AMDGPU-Pro. Platform needs to say AMD-APP not Clover. apt purge mesa-opencl-icd

Ubuntu desktop tends to come with Clover preinstalled, Server doesn't. Betting you've installed Desktop version of Ubuntu 18? We probably should add to docs about removing clover this is the second recent occurrence of this from the same vector (install Desktop -> AMDGPU-Pro doesn't override Clover)

The buggy part is that there should be two platforms, Clover and then AMD-APP side by side, or that's how older versions seemed to work. Then you could leave Clover there and just set platform:1 or such to avoid it and use the AMD one. But you've got only the single platform just like the other issue, so it must be new bugs.

Also unless you've got Vega use the legacy opencl option for the AMDGPU-Pro installer (no rocm).

you don't need to uninstall mesa. xmr-stak will only try (and fail) to use mesa if it doesn't detect the AMDGPU-Pro platform.

[Spudz76]

Something in the installer skips the amdgpu-pro-igd if another is already available, though, apparently.

Agree it "used to" just have the dual platforms and worked fine by ignoring the Clover one. But not anymore for some reason (Ubuntu 18).
