AMD SMI Python API reference

The AMD SMI Python interface provides a convenient way to interact with AMD hardware through a simple and accessible API. Compatible with Python 3.6 and higher, this library requires the AMD driver to be loaded for initialization -- review the prerequisites.

This section provides comprehensive documentation for the AMD SMI Python API. Explore these sections to understand the full scope of available functionalities and how to implement them in your applications.

  • Cursor is the index of the next cper entry in the GPU ring buffer. For example, if 10 entries were fetched successfully, the value of cursor will be 11 upon return from the API. Subsequent call to the API with cursor value of 11 should fetch the next entry

Output3: A list of dictionaries, each dictionary containing the CPER record and its size:

  • {"bytes": , "size": }

Output4: status_code AMDSMI_STATUS_SUCCESS: If all entries were retrieved successfully AMDSMI_STATUS_MORE_DATA: If some of the entries were retrieved and: * A subsequent call to the API with the updated cursor will result in the fetching the next batch of entries, or * Increasing the input buffer_size will allow more entries to be fetched with the same cursor
