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().
