Function Documentation

GPUart_Retval gpuI_memcpyConstantMemory	(	void *	variable_p,
		device_constant_memory_id_e	id_p
	)

Copy data from host memory to constant device memory.

The copy is only possible if persistent GPUart kernel GPUart_Persistent_Kernel is not running, since a constant memory data is immutable during kernel execution and its value is inherited from parent to child kernel.

Parameters

[in]	void	* variable_p -> The host variable to be copied
[in]	device_constant_memory_id_e	id_p -> The ID of the constant memory buffer

Returns

GPUART_SUCCESS if memory copy operation has been successfully.

GPUART_ERROR_INVALID_ARGUMENT if id_p is an invalid ID.

GPUart_Retval gpuI_memcpyDevice2Host	(	void *	variable_p,
		device_global_memory_id_e	id_p
	)

Copy data from device memory to host memory.

Device memory may be shared physical memory or discrete device memory. The device driver API call may depend on the type of device memory (global or texture memory).

Parameters

[out]	void	* variable_p -> The host variable to be written
[in]	device_global_memory_id_e	id_p -> The ID of the global memory variable

Returns

GPUART_SUCCESS if memory copy operation has been successfully.

GPUART_ERROR_INVALID_ARGUMENT if id_p is an invalid ID.

GPUart_Retval gpuI_memcpyHost2Device	(	void *	variable_p,
		device_global_memory_id_e	id_p
	)

Copy data from host memory to device memory.

Device memory may be shared physical memory or discrete device memory. The device driver API call may depend on the type of device memory (global or texture memory).

Parameters

[in]	void	* variable_p -> The host variable to be copied
[in]	device_global_memory_id_e	id_p -> The ID of the global memory variable

Returns

GPUART_SUCCESS if memory copy operation has been successfully.

GPUART_ERROR_INVALID_ARGUMENT if id_p is an invalid ID.
