Overview
The Device System Manage Interface (DSMI) provides APIs for the Ascend AI Processor management, including device, MAC address, and configuration management, software upgrade as well as the Ascend AI Processor reset and boot. Through these APIs, the the Ascend AI Processor quantity, health status, temperature, sensor, and much more information can be obtained, facilitating the the Ascend AI Processor monitoring.
The root user described in this document refers to the root user on the host side.
- Due to the restriction of the DSMI session, in concurrent scenarios under a common user, a device allows a maximum of eight threads or processes to call the DSMI APIs at the same time.
- The main process and its subprocesses cannot call DSMI APIs at the same time.
- The returns and outputs of APIs described in this document need to be validated before use.
