rmlCreateTensorFromMTLBuffer

Creates a tensor from an existing Metal buffer.

rml_status rmlSetMIOpenAutoTuningOn(	rml_context context,
	void* buffer,
	const rml_tensor_info* info,
	rml_access_mode mode,
	rml_tensor* tensor);

API

Metal Interoperation

Parameters

Parameter	Input/Output	Description
context	input	A valid context handle.
buffer	input	An MTLBuffer instance (id<MTLBuffer>).
info	input	A tensor description with all dimensions specified.
mode	input	A tensor access mode.
tensor	output	A pointer to a resulting tensor handle.

Return and Status Codes

Returns a valid tensor handle in case of success and status:

• RML_OK if the operation is successful

• RML_ERROR_BAD_PARAMETER if the context is invalid, the buffer is NULL, the info is NULL or invalid, the mode is invalid or the tensor is NULL

• RML_ERROR_INTERNAL in case of an internal error

To get more details in case of failure, call rmlGetLastError().

The tensor should be released with rmlReleaseTensor().
