The problem is finding a general way for OpenCL to force it to run on the CPU. For Mesa OpenGL there is LIBGL_ALWAYS_SOFTWARE, but for OpenCL there is nothing similar. > Meanwhile, =media-gfx/imagemagick-6.8.8.10[opencl] now installs the > sandbox.d file, > workaround is better here than nothing since this is affecting multiple > binaries, > packages :/ > > - Samuli > For ImageMagick specifically, the MAGICK_OCL_DEVICE environment variable could be set per[1]. Another option would be to hide the existence of the GPU OpenCL device from the applications using the OCL_ICD_VENDORS variable.
