clinfo seems happy
Up to date Arch Linux, including: linux 4.18.12.arch1-1, xf86-video-amdgpu
18.1.0-1, mesa 18.2.2-1, opencl-mesa 18.2.2-1, xorg-server 1.20.1-1, and
plasma-desktop 5.13.5-1.
(Recently installed system that STARTED with: linux 4.18.9.arch1-1, mesa
18.2.1-1, and opencl-mesa 18.2.1-1.)
I have not tried AMDGPU-PRO. (Not really interested anyway, and the Arch AUR
package for it is 17.40, which requires downgrading to linux 4.9 and Xorg
1.18.)
$ lspci -k | grep VGA
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Ellesmere [Radeon RX 470/480/570/570X/580/580X] (rev e7)
Subsystem: XFX Pine Group Inc. Ellesmere [Radeon RX
470/480/570/570X/580/580X]
Kernel driver in use: amdgpu
Kernel modules: amdgpu
It's the: XFX AMD Radeon RX 580 GTS Black Edition 8GB GDDR5 PCI Express 3.0

Anything using OpenCL immediately segfaults.
Everything that segfaults runs just fine if I uninstall opencl-mesa, and either
use opencl-amd (Arch linux package, which extracts OpenCL library from
AMDGPU-PRO **18.30** but allows it to run with the open source AMDGPU driver.)
Everthing also runs fine if I instead use intel-opencl-runtime to just run off
the CPUs.
-----
luxmark 3.1 crashes in pipe_radeonsi.so, called by libMesaOpenCL.so.1, called
by libOpenCL.so.1.
A gdb backtrace with opencl-mesa 18.2.2 that I compiled in debug mode with
symbols is attached or here: <a href="http://termbin.com/to7v">http://termbin.com/to7v</a>
A gdb backtrace with opencl-mesa 18.2.2 (Arch binary, so without buildtype
specified and no symbols) is here: <a href="http://termbin.com/m1yx">http://termbin.com/m1yx</a>
Setting environment variable MESA_DEBUG causes no additional output.
-----
Granted, IndigoBenchmark_x64_v4.0.64 crashes by calling
/usr/lib/libOpenCL.so::clGetPlatformIDs() which is ocl-icd, but without
opencl-mesa and instead with opencl-amd, it runs through it just fine.
