"cl_qcom_perf_hint", "cl_qcom_priority_hint" extn support added over workspace interface. OpenCL version will be picked up from SDK headers. CI fixes for build without Adreno OpenCL SDK. Entensions are activated based on its availability in SDK. New workspace API "SetNativePtr" defined that releases existing cl_mem and creates new mem object backed by given host ptr. Works for cl_qcom_ion_host_ptr, cl_qcom_android_ahardwarebuffer_host_ptr, cl_qcom_android_native_buffer_host_ptr, cl_qcom_dmabuf_host_ptr and cl_qcom_ion_host_ptr. The responsibility of preparing the host_ptr objects is with application. Some times the application needs device id for various devices related information. Use below ref. to get cl_device_id from workspace. OpenCLWorkspace* workspace = OpenCLWorkspace::Global(); cl_device_id device_id = workspace->GetCLDeviceID(0);
