Joe Howse 6a3d925a47 OpenCL: core support for FP16, more channel orders ... * Support cl_image conversion for CL_HALF_FLOAT (float16) * Support cl_image conversion for additional channel orders: CL_A, CL_INTENSITY, CL_LUMINANCE, CL_RG, CL_RA * Comment on why cl_image conversion is unsupported for CL_RGB * Predict optimal vector width for float16 * ocl::kernelToStr: support float16 * ocl::Device::halfFPConfig: drop artificial requirement for OpenCL version >= 1.2. Even OpenCL 1.0 supports the underlying config property, CL_DEVICE_HALF_FP_CONFIG. * dumpOpenCLInformation: provide info on OpenCL half-float support and preferred half-float vector width * randu: support default range [-1.0, 1.0] for float16 * TestBase::warmup: support float16		2021-06-30 14:14:37 -03:00
