The test is bogus. (In reply to Chris Wilson from comment #1) > The test is bogus. Hi Chris, could you explain more detail why the test is bogus? Thanks. There are also some opencv tesst fail when disable RC6. ./opencv_test_calib3d --gtest_filter=OCL_StereoMatcher/StereoBMFixture.* ./opencv_test_core --gtest_filter=OCL_Arithm/Transpose.* The reproducibility of opencv cases is >50%. Please see attached log. Created attachment 115895 [details]

==Regression== -------------------------- Regression: No. Firstly tests OpenCL on BSW. Ubuntu: 14.04 ==kernel== -------------------------- drm-intel-next-queued: git-65de79 ==Test cases== Beignet: git://anongit.freedesktop.org/git/beignet (master git-6aae2e8) failed cases: compiler_async_copy_char2 compiler_async_copy_uchar2 ==Bug detailed description== ----------------------------- Disable RC6 in kernel makes some OpenCL test cases fail. If enable RC6(no i915.enable_rc6=0 in grub), the case works OK. e.g. run compiler_async_copy_char2() compiler_async_copy_char2() [FAILED] Error: dst[i] == src[i] at file /home/OpenCL/beignet/utests/compiler_async_copy.cpp, function compiler_async_copy_char2, line 46 ==Reproduce steps== ---------------------------- 1. set "i915.enable_rc6=0" 2. utests/utest_run -c compiler_async_copy_char2
