Request for PCIE Slot ID in TT-SMI

[hmohiuddinTT]

Cards locations are identified by which PCIe slot they are installed in on a motherboard. Currently there's no way to identify which slot a card is installed in on tt-smi. We work around this by mapping device_id (/dev/tenstorrent/*) -> PCIe bus id -> slot ID via the following command:

sudo dmidecode -t slot

It would be helpful to both cloud and customers if we can get this integrated into SMI.

As an example the following ansible playbook prints the mapping:

---
- name: Check slot ids for boards installed on host
  hosts: compute
  gather_facts: false
  become: true
  tasks:
    - name: Get all board PCIe bus IDs
      ansible.builtin.shell: "lspci -d 1e52: | awk '{print $1}'"
      register: lspci_output
      changed_when: false

    - name: Get slot ID for each bus ID
      ansible.builtin.shell: dmidecode -t slot | grep -B8 {{ item }} | grep "Designation:" | awk -F ':' -F ' ' '{print $2}' | xargs
      register: slot_mappings
      loop: "{{ lspci_output.stdout_lines }}"
      when: lspci_output.stdout_lines | length > 0
      changed_when: false

    - name: Print slot IDs
      ansible.builtin.debug:
        msg: "{{ slot_mappings.results | map(attribute='stdout') | zip(lspci_output.stdout_lines) | map('join', ' | ') | join('\n') }}"
      when: lspci_output.stdout_lines | length > 0

Please also add this info to the --list output along with bus id
