Member Function Documentation

fromBinary()

static ProgramSource cv::ocl::ProgramSource::fromBinary ( const String &  module, const String &  name, const unsigned char *  binary, const size_t  size, const cv::String &  buildOptions = cv::String()  )

static

Describe OpenCL program binary. Do not call clCreateProgramWithBinary() and/or clBuildProgram().

Caller should guarantee binary buffer lifetime greater than ProgramSource object (and any of its copies).

This kind of binary is not portable between platforms in general - it is specific to OpenCL vendor / device / driver version.

Parameters

module	name of program owner module
name	unique name of program (module+name is used as key for OpenCL program caching)
binary	buffer address. See buffer lifetime requirement in description.
size	buffer size
buildOptions	additional program-related build options passed to clBuildProgram()

Returns

created ProgramSource object

fromSPIR()

static ProgramSource cv::ocl::ProgramSource::fromSPIR ( const String &  module, const String &  name, const unsigned char *  binary, const size_t  size, const cv::String &  buildOptions = cv::String()  )

static

Describe OpenCL program in SPIR format. Do not call clCreateProgramWithBinary() and/or clBuildProgram().

Supports SPIR 1.2 by default (pass '-spir-std=X.Y' in buildOptions to override this behavior)

Caller should guarantee binary buffer lifetime greater than ProgramSource object (and any of its copies).

Programs in this format are portable between OpenCL implementations with 'khr_spir' extension: https://www.khronos.org/registry/OpenCL/sdk/2.0/docs/man/xhtml/cl_khr_spir.html (but they are not portable between different platforms: 32-bit / 64-bit)

Note: these programs can't support vendor specific extensions, like 'cl_intel_subgroups'.

Parameters

module	name of program owner module
name	unique name of program (module+name is used as key for OpenCL program caching)
binary	buffer address. See buffer lifetime requirement in description.
size	buffer size
buildOptions	additional program-related build options passed to clBuildProgram() (these options are added automatically: '-x spir' and '-spir-std=1.2')

Returns

created ProgramSource object.
