size: size_t,
build_options: &str
) -> Result<ProgramSource>
pub fn from_binary( module: &str, name: &str, binary: &u8, size: size_t, build_options: &str ) -> Result<ProgramSource>
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
C++ default parameters
- build_options: cv::String()
sourcepub fn from_spir(
module: &str,
name: &str,
binary: &u8,
size: size_t,
build_options: &str
) -> Result<ProgramSource>
pub fn from_spir( module: &str, name: &str, binary: &u8, size: size_t, build_options: &str ) -> Result<ProgramSource>
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.
C++ default parameters
- build_options: cv::String()
