[SOLVED] OpenCL configuration on AMD KAVERI (APU)
I'm quite puzzled to be honest, so I've decided to ask on forum.
I've installed all needed packages (opencl-mesa, ocl-icd + clinfo).
Judging by clinfo everything is fine and should work(?):

OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20And yet any program that uses OpenCL complains that I don't have OpenCL (for instance, Blender is saying "No compatible GPUs found for path tracing. Cycles will render on CPU" when I chose OpenCL in settings).
Am I missing something? Is there any way to test OpenCL further?
Thanks to everybody in advance!

Re: [SOLVED] OpenCL configuration on AMD KAVERI (APU)
In case that matters in this case. I'm using amdgpu module, not radeon
lspci -k
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R7 Graphics] (rev d4)
Subsystem: ASUSTeK Computer Inc. Device 85cb
Kernel driver in use: amdgpu
Kernel modules: radeon, amdgpuOffline

Re: [SOLVED] OpenCL configuration on AMD KAVERI (APU)
Blender doesn't work well with opencl opensource drivers, the others may need higher opencl versions then the 1.1 provided by clover (opencl-mesa).
Try opencl-amd from aur .
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Thanks, it worked!
Too bad there is such a bad support of FOSS OpenCL everywhere...
