[Issue]: amd-smi C++ Interface does not report correct information in MI300A

[garrettbyrd]

Problem Description

Here is a quick cpp file that iterates over sockets and should list the names and devices on each socket.

#include <iostream>
#include <unistd.h>
#include <amd_smi/amdsmi.h>

int main() {
    amdsmi_status_t status = amdsmi_init(AMDSMI_INIT_AMD_APUS);
    if (status != AMDSMI_STATUS_SUCCESS) {
       std::cerr << "Failed to initialize AMD SMI library" << std::endl;
       return -1;
    }

    uint32_t socket_count = 0;
    status = amdsmi_get_socket_handles(&socket_count, nullptr);
    std::cout << "Socket Total: " << socket_count << std::endl;
    std::vector<amdsmi_socket_handle> sockets(socket_count);

    for (uint32_t i = 0; i < socket_count; i++) {
        uint32_t device_count = 0;
        status = amdsmi_get_processor_handles(sockets[i], &device_count, nullptr);
        std::vector<amdsmi_processor_handle> processor_handles(device_count);
        status = amdsmi_get_processor_handles(sockets[i], &device_count, &processor_handles[0]);

        for (uint32_t j = 0; j < device_count; j++){
           // Get device type
           processor_type_t processor_type;
           status = amdsmi_get_processor_type(processor_handles[j], &processor_type);
           std::cout << "processor type: " << processor_type << std::endl;

           // Get device name
           amdsmi_board_info_t board_info;
           status = amdsmi_get_gpu_board_info(processor_handles[j], &board_info);
           std::cout << "\tdevice: " << j << "\n\t\tname:" << board_info.product_name << std::endl;
        }

        std::cout << "socket: " << i << std::endl;
        std::cout << "device count: " << device_count << std::endl;
     }

    status = amdsmi_shut_down();

    return 0;
}

However, amd-smi reports zero devices per socket:

Socket Total: 8
socket: 0
device count: 0
socket: 1
device count: 0
socket: 2
device count: 0
socket: 3
device count: 0
socket: 4
device count: 0
socket: 5
device count: 0
socket: 6
device count: 0
socket: 7
device count: 0
