I've been trying to experiment with OpenCL but I just can't get it
working. I've installed devel/ocl-icd and devel/clinfo. I installed
lang/beignet on a system with Ivy Bridge graphics and loaded the i915kms
module. On another system I used the lang/pocl driver instead. Whenever
I try to use anything OpenCL I get a segfault.
For example:
# clinfo
Number of platforms 1
Platform Name Intel Gen OCL Driver
Platform Vendor Intel
Platform Version OpenCL 1.2 beignet 1.3
Platform Profile FULL_PROFILE
Platform Extensions
cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics
cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics
cl_khr_byte_addressable_store cl_khr_3d_image_writes
cl_khr_image2d_from_buffer cl_khr_depth_images cl_khr_spir cl_khr_icd
cl_intel_accelerator cl_intel_subgroups cl_intel_subgroups_short
Platform Extensions function suffix Intel
