[Beignet] [PATCH v5 3/4] Add basic utest for block_motion_estimate_intel.

If the CL device does not support this builtin kernel, the test returns PASS. Signed-off-by: Guo Yejun --- utests/CMakeLists.txt | 1 + .../builtin_kernel_block_motion_estimate_intel.cpp | 109 + utests/utest_helper.hpp

[Beignet] [PATCH v5 2/4] Add extensions intel_accelerator and basic intel_motion_estimation.

v2: 1. Just upload the first vme_state. 2. Remove duplicated code in check_opt1_extension. 3. Check image format before cl_gpgpu_bind_image_for_vme. 4. Fix error of getting mv. Because we suppose this kernel run in SIMD16 mode, so dword 0 of grf 1 should be __gen_ocl_region(8,vme_result.s0),

[Beignet] [PATCH v5 1/4] Add built-in function __gen_ocl_vme.

__gen_ocl_vme is used for hardware accelerated video motion estimation. It gets payload values as parameters and uses MOV to pass these payload values to VME SEND Message's payload grfs. The int8 return value is used to store SEND Message writeback. v2: Remove unnecessary 5 parameters(src_grf*)

Re: [Beignet] Does LLVM 3.6 still hit a bug?

When was this workaround done (in particular, is beignet 1.1.1 affected)? As the Khronos test suite is non-public, I can't test this myself. Debian have now announced an intention to remove LLVM 3.5 (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=803643). An alternative option (which I

[Beignet] [PATCH] Don't read past end of printf format string

Reading p+1 when p==end is an out of bounds read. Signed-off-by: Rebecca Palmer --- (Found by valgrind while investigating #90472; probably not the actual cause of that crash, but still a bug.) diff --git a/backend/src/llvm/llvm_printf_parser.cpp

Re: [Beignet] [PATCH] Don't read past end of printf format string

Hi Rebecaa, Nice catch! This is the root cause of a bug I was recently trying to fix, it will cause printf randomly fail if *(p+1) is accidently is '%'. So could you resend a patch with a start "GBE:." and some more description about the bug fix. Thanks Xiuli Pan -Original

Re: [Beignet] Does LLVM 3.6 still hit a bug?

We found that it's a miss understanding of a corner case in type conversion, not a llvm bug. In that case the cl kernel try to convert an overflowed float value to ulong e.g. ulong dst = (ulong)1.8446744073709552e+19f; // this is an overflowed ulong value with llvm3.5 the result value is
