I think there's a bug, but I'm not quite sure what the cause is. Neither ethminer nor Claymore will launch unless there's an active X session running. They will both say that no OpenCL devices were found.

GPU_FORCE_64BIT_PTR=1 was enough for me (HD7950)

difron commented on 2017-10-21 13:13

It works on SI if set

export GPU_FORCE_64BIT_PTR=1
export GPU_MAX_HEAP_SIZE=100

found here

@darkbasic: I don't think so. SI was not initially planned for AMDGPU. You can try the AMD mainline kernel as suggested in the thread, but I'm not sure if it will work.

darkbasic commented on 2017-09-27 23:44

Is it supposed to work on SI?

probably a dumb question, but I can't get OpenCL to work without root. I tried adding myself to the video group, but it's still not working.

Works with libdrm 2.4.82-1

Thanks for reporting. The file is located under '/usr/share/libdrm' with the upstream libdrm package and I've just linked it accordingly.

However, Alex Deucher also started pushing the libdrm changes by AMD which are required for their hybrid stack publicly[1].

It should now be possible to stop this approach for the OpenCL driver and replace libdrm with libdrm-amd[2]. The hybrid branch at [3] is intended to work with that (also includes Vulkan), but I've had no time to test things yet. I've set the linux-amd-mainline-git kernel as a dependency, which can be found in the AUR[4] and is also pushed out publicly now.

I believe the source directory has changed in the package, as a quick workaround I just made the directory and created a symlink to the copy on my system and it seems to be working fine. I didn't have a copy of the file in /opt where it was expected, in fact the directory didn't exist on my system.

Not a great solution but it's a quick workaround

sudo find /usr/ -iname "amdgpu.ids" -exec stat -c "%a %n %y" {} \;
644 /usr/share/libdrm/amdgpu.ids 2017-07-19 10:52:24.000000000 -0400

mkdir -p /opt/amdgpu-pro/share/libdrm/
sudo ln -s /usr/share/libdrm/amdgpu.ids /opt/amdgpu-pro/share/libdrm/amdgpu.ids

Checking on my Ubunutu 16.04 box that I updated the driver yesterday /usr/share/libdrm/amdgpu.ids does seem to be the last one updated as well so I'd assume they decided to move it but forgot to update some dependencies, but that is just a guess
