Regarding OpenCL support on i.MX8 family processors

Hello all,


I was wondering about the current state of OpenCL support on i.MX8 processors, specifically for machine learning applications using NXP eIQ framework.


According to NXP eIQ Machine Learning Software Development for i.MX Application Processors "OpenCL is currently not supported in the L4.14.98_2.0.0 and L4.14.78_1.0.0 Yocto configurations" for OpenCV. Has this changed for newer releases because according the example hereeIQ Sample Apps - Object Recognition using OpenCV DNN OpenCL can be used with OpenCV?


Also do any of the samples in NXP eIQ framework have hardware acceleration support? eIQ™ ML Software Development Environment | NXP landing page states that only Arm NN and TensorFlowLite have GPU support however it is also stated that "Arm NN does not currently support the i.MX 8 GPUs due to the Arm NN OpenCL requirements, which are not met by i.MX 8 GPUs.


I would be grateful if somebody could clarify these.


Thanks in advance,
