Alexander Alekhin	75f28245a8	core: fix persistence bug in RAW I/O code - persistence.cpp code expects special sizeof value for passed structures - this assumption is lead to memory corruption problems - fixed/workarounded test to prevent memory corruption on Linux 32-bit systems	8 years ago
Pavel Vlasov	11c2ffaf1c	Update for IPP for OpenCV 2017u2 integration; Updated integrations for: cv::split cv::merge cv::insertChannel cv::extractChannel cv::Mat::convertTo - now with scaled conversions support cv::LUT - disabled due to performance issues Mat::copyTo Mat::setTo cv::flip cv::copyMakeBorder - currently disabled cv::polarToCart cv::pow - ipp pow function was removed due to performance issues cv::hal::magnitude32f/64f - disabled for <= SSE42, poor performance cv::countNonZero cv::minMaxIdx cv::norm cv::canny - new integration. Disabled for threaded; cv::cornerHarris cv::boxFilter cv::bilateralFilter cv::integral	8 years ago

insoow	2922738b6d	Merge pull request #8104 from insoow:master Gemm kernels for Intel GPU (#8104) * Fix an issue with Kernel object reset release when consecutive Kernel::run calls Kernel::run launch OCL gpu kernels and set a event callback function to decreate the ref count of UMat or remove UMat when the lauched workloads are completed. However, for some OCL kernels requires multiple call of Kernel::run function with some kernel parameter changes (e.g., input and output buffer offset) to get the final computation result. In the case, the current implementation requires unnecessary synchronization and cleanupMat. This fix requires the user to specify whether there will be more work or not. If there is no remaining computation, the Kernel::run will reset the kernel object Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * GEMM kernel optimization for Intel GEN The optimized kernels uses cl_intel_subgroups extension for better performance. Note: This optimized kernels will be part of ISAAC in a code generation way under MIT license. Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * Fix API compatibility error This patch fixes a OCV API compatibility error. The error was reported due to the interface changes of Kernel::run. To resolve the issue, An overloaded function of Kernel::run is added. It take a flag indicating whether there are more work to be done with the kernel object without releasing resources related to it. Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * Renaming intel_gpu_gemm.cpp to intel_gpu_gemm.inl.hpp Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * Revert "Fix API compatibility error" This reverts commit `2ef427db91`. Conflicts: modules/core/src/intel_gpu_gemm.inl.hpp * Revert "Fix an issue with Kernel object reset release when consecutive Kernel::run calls" This reverts commit `cc7f9f5469`. * Fix the case of uninitialization D When C is null and beta is non-zero, D is used without initialization. This resloves the issue Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * fix potential output error due to 0 * nan Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * whitespace fix, eliminate non-ASCII symbols * fix build warning	8 years ago

Fangjun KUANG	5e4dfb9546	Change the argument type to cl_platform_info. Although both `cl_platform_info` and `cl_device_info` are defined as macro `cl_uint`, it needs to use `cl_platform_info` to get the platform information.	8 years ago
Alexander Alekhin	4c7aa8645a	ocl: validate arguments in KernelArgs constructor - don't use undefined flag=0. It should be CONSTANT instead. - don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags). This case is not handled well to provide NULL __global pointers. It is better to use '-D' macro defines instead (at least for performance)	8 years ago
