Function Documentation

◆ amdsmi_init()

amdsmi_status_t amdsmi_init ( uint64_t init_flags )

Initialize the AMD SMI library.

This function initializes the library and the internal data structures, including those corresponding to sources of information that SMI provides.

The init_flags decides which type of processor can be discovered by amdsmi_get_socket_handles(). AMDSMI_INIT_AMD_GPUS returns sockets with AMD GPUS, and AMDSMI_INIT_AMD_GPUS | AMDSMI_INIT_AMD_CPUS returns sockets with either AMD GPUS or CPUS. Currently, only AMDSMI_INIT_AMD_GPUS is supported.

Parameters

[in] init_flags Bit flags that tell SMI how to initialze. Values of amdsmi_init_flags_t may be OR'd together and passed through init_flags to modify how AMDSMI initializes.

Returns: amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

◆ amdsmi_shut_down()

amdsmi_status_t amdsmi_shut_down ( void )

Shutdown the AMD SMI library.

This function shuts down the library and internal data structures and performs any necessary clean ups.

Returns: amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail
