Bug ID: 102491 Summary: OpenCL app gets CL_OUT_OF_HOST_MEMORY on Cape Verde 7770 Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu-pro Assignee: dri-devel@lists.freedesktop.org Reporter: ka.nick@mail.ru

Trying to couple mainline amdgpu driver with opencl from amdgpu-pro (installed via Gentoo dev-libs/amdgpu-pro-opencl package) to make darktable use opencl again. Clinfo and apps see the opencl but when trying to create a command queue driver returns CL_OUT_OF_HOST_MEMORY. The same behavior is reported on Ubuntu 16.04.3 as seen here https://redmine.darktable.org/issues/11702
kernel 4.12.0-pf7 xorg-server-1.19.3 libdrm-2.4.82 xorg-1.19.3 x11-drivers/xf86-video-amdgpu-1.3.0 dev-libs/amdgpu-pro-opencl-17.30.465504

--- Comment #5 from ka.nick@mail.ru --- I managed to make it work somehow, but it's still unusable due to producing artifacts on images processed using opencl on darktable and few other programs I tried. So probably the title should be changed.
However, CL_OUT_OF_HOST_MEMORY error may be removed via envitonment var setting, namely
export GPU_FORCE_64BIT_PTR=1
also
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export GPU_SINGLE_ALLOC_PERCENT=100 export GPU_MAX_HEAP_SIZE=100
are recommended but I haven't noticed any difference. What I've noticed, however, is that the driver reports the different amount of available GPU memory each time darktable is started...
