darktable-cltest output

Installed dev-libs/amdgpu-pro-opencl for 7770 Cape Verde card. Clinfo reports look fine, but darktable fails with 
[opencl_init] could not create command queue for device 0: -6
Other apps I tried see opencl but don't work either. Looks like permission or setup/configuration problem. Please help.
kernel 4.12.0-pf6
xorg-server-1.19.3
libdrm-2.4.82
x11-drivers/xf86-video-amdgpu-1.3.0

Could you run darktable with debug information enabled and see if it produces any more information?

Comment 4 Nick 2017-08-17 06:53:04 UTC

darktable -d opencl provides exactly the same info as darktable-cltest.
What I probably can do is to open another issue on darktable bug tracker and provice the link to this bug so you guys may communicate... I really interested in getting opencl eventually work again. Having dumped fglrx AMD left me without fast darktable for more than half a year so far...

Comment 5 Nick 2017-08-21 12:56:48 UTC

Here comes the reply I got from darktable bug tracker:

From darktable-cltest's output:

[opencl_init] could not create command queue for device 0: -6
Error code -6 relates to CL_OUT_OF_HOST_MEMORY. And that's what the docs tell us about this error during command queue creation:

CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the
OpenCL implementation on the host.

I guess it's a driver bug.

Don't works with R7 250.It causes a segmentation fault.

Comment 7 Francisco Lloret 2017-12-06 10:18:22 UTC

R7 250 died. I installed a new Rx 580 card.

After the upgrade to GCC 5 and recompilation of all world, it works using last stable kernel (4.12.12)

Well, seeing as OpenCL clients do see devices there really isn't much I could can do here, is there... What happens inside is entirely up to AMD.
