Detailed Description

Binds host data and memory buffers per engine describing data direction (in/out) for kernel.

Definition at line 126 of file engine.hpp.

Constructor & Destructor Documentation

◆ buffer_binding() [1/2]

buffer_binding	(	void *	ptr,
		size_t	size = `0`,
		direction	dir = `inout`
	)

inline

Constructs binding from host-allocated buffer.

Parameters

ptr	Raw pointer to host allocated data
size	Size of host allocated data
dir	Data direction: host->kernel or host<-kernel or both

Definition at line 134 of file engine.hpp.

◆ buffer_binding() [2/2]

buffer_binding	(	const std::shared_ptr< buffer > &	buffer,
		direction	dir = `inout`,
		size_t	size = `0`
	)

inline

Constructs binding from engine-allocated memory buffer.

Parameters

buffer	Pre-allocated memory buffer
dir	Data direction: host->kernel or host<-kernel or both
size	Size of data to be used - should be less or equal to buffer size, if set to 0 then buffer size will be used.

Definition at line 149 of file engine.hpp.

Member Function Documentation

◆ get_buffer()

std::shared_ptr<buffer> get_buffer ( const std::shared_ptr< engine > & engine ) const

Returns binded buffer for the specified engine.

If there is no buffer binded - create and register new binded buffer

◆ get_host_ptr()

void* get_host_ptr ( ) const

Raw pointer to data.

Returns: Host-allocated pointer or mapped buffer depending on constrcution.

◆ set_direction()

direction set_direction ( direction dir )

Set direction of the binding.

Returns: Previous value

◆ size()

void size ( size_t size )

Set new size.

New size should be less or equal to capacity
