Created attachment 116428 [details] Utest Report file System: Ubuntu 14.04 (kernel 3.13.0-53-generic) CPU: Intel(R) Core(TM) i5-4200M GPU: Intel(R) HD Graphics Haswell GT2 Mobile Version: OpenCL 1.2 beignet 1.1 (git-48e22ae) -------------------------- This tests failed on my system: compiler_atomic_functions() [FAILED] compiler_async_copy_char2() [FAILED] compiler_async_copy_uchar2() [FAILED] compiler_async_copy_short2() [FAILED] compiler_async_copy_ushort2() [FAILED] compiler_async_copy_int2() [FAILED] compiler_async_copy_uint2() [FAILED] compiler_async_copy_long2() [FAILED] compiler_async_copy_ulong2() [FAILED] compiler_async_copy_float2() [FAILED] compiler_async_stride_copy() [FAILED] compiler_load_bool_imm() [FAILED] compiler_local_memory_two_ptr() [FAILED] compiler_local_memory_barrier() [FAILED] compiler_local_memory_barrier_wg64() [FAILED] compiler_local_memory_barrier_2() [FAILED] compiler_local_slm() [FAILED] compiler_getelementptr_bitcast() [FAILED] I was tried both GCC and Clang 3.5 for compilation. I was also compiled kernel with path for shared local memory (as described here http://arrayfire.com/opencl-on-intel-hd-iris-graphics-on-linux/). But how I can check it's really installed? My main problem is this version do not work correctly in Blender 2.74 with Cycles Render. It produce corrupted color less image.
Also I get this error when I run "clinfo" Beignet: self-test failed: (3, 7, 5) + (5, 7, 3) returned (3, 7, 5) Beignet: Warning - overriding self-test failure
Self test failed means the SLM doesn't work correctly. Please check the README.md's known issue section: * "Beignet: self-test failed" and 15-30 unit tests fail on 4th Generation (Haswell) hardware. On Haswell, shared local memory (\_\_local) does not work at all on Linux <= 4.0, and requires the i915.enable_ppgtt=2 [boot parameter](https://wiki.ubuntu.com/Kernel/KernelBootParameters) on Linux 4.1. This will be fixed in Linux 4.2; older versions can be fixed with [this patch](https://01.org/zh/beignet/downloads/linux-kernel-patch-hsw-support). If you do not need \_\_local, you can override the self-test with `export OCL_IGNORE_SELF_TEST=1` but using \_\_local after this may silently give wrong results. Please make sure you are using latest linux kernel for HSW machine.
I already done all I can from things described in Readme.md. I recompiled kernel with provide patch, but this does not change anything. What else I can do? Does Beignet will work correctly in Blender with new linux kernel 4.2? P.S. But I'm not sure that the kernel I compiled and installed via dpkg is actually in use. It must be, but I don't know how to check this. I will try to figure it out.
[FIXED] Solution: 1) Recompile linux kernel with provided path for _local as described in Readme.md. 2) Install kernel correctly (*do not miss any packages). In my case I was missed linux-headers-XXXX_all.deb For me it was: linux-headers-3.13.0-53_3.13.0-53.89_all.deb linux-headers-3.13.0-53-generic_3.13.0-53.89_amd64.deb linux-image-3.13.0-53-generic_3.13.0-53.89_amd64.deb linux-image-extra-3.13.0-53-generic_3.13.0-53.89_amd64.deb
