Describe the bug Unable to run ethminer due to segmentation fault with either opencl-mesa or opencl-amd

To Reproduce Clone latest source code Configure with cmake .. -DETHASHCUDA=OFF -DUSE_SYS_OPENCL=ON -DHUNTER_ENABLED=ON Compile successfully Run: --> ethminer -G -P stratum+tcp://redactedUser.1:x@us-east.ethash-hub.miningpoolhub.com:20535

Expected behavior no segmentation fault

Same issue, cloned ethminer from the AUR.

Scr0nch commented 3 years ago

I encountered this same crash when using the default mesa driver shipped with Manjaro after installing ethminer from the AUR. After about 10 hours of debugging, the way I fixed it is this:

  1. Install the opencl-amd package from the AUR Note: I encountered a problem where the DAG was never generated using the latest version of this package. Downgrading this package to version 20.40 fixed the issue because, as AMD mentioned in their release notes for 20.45, "User may experience issues when utilizing OpenCL in multimedia use cases." To install the 20.40 version, download the older PKGBUILD file and manually install it. Note 2: compiling ethminer with -DBINKERN=OFF as mentioned in this issue did not fix the issue using version 20.45 of opencl-amd for me.
  2. Find the id of the duplicate graphics card entry created by the AMDGPU proprietary driver by passing --list-devices to ethminer. For me the gfx1010 entry has an id of 1
  3. Add --cl-devices 1 to your ethminer flags where 1 is the id from step 2.

This solved the problem for me.

If you install opencl-amd and compile ethminer with -DUSE_SYS_OPENCL=ON you don't need to specify the device (at least for me, and I was having this problem before I did this).
