Add information about version of gaudi device

[kkurzacz-intel]

User story

As a perfspect user, I'd love to know what Gaudi version is installed (gaudi1, gaudi2 or gaudi3). This information is as useful for me as CPU architecture (ICX, SPR...)

Regarding especially JSONs, information could, for example, stay at .["Gaudi"][*]["Microarchitecture"], i.e:

  "Gaudi": [
    {
      ...,
      "Microarchitecture": "gaudiN"
      ...,
    },
    ...,

where N belongs to {1, 2, 3}

I used "Microarchitecture" key as suggestion, because currently for CPUs, the model kind stays as same key.

Current Perfspect version: 3.9.0_2025-08-14_e3811ca8

As of now, information about currently installed Gaudi version is missing. Unfortunately, it's not easily available. Current BKM I was told exists in an habana gaudi driver installer habanalabs-installer.sh:

    __DEFAULT_HL_DEVICE=
    __pcidev=$(grep PCI_ID /sys/bus/pci/devices/*/uevent | grep -i 1da3: || echo "")
    if echo $__pcidev | grep -qE '1000|1001|1010|1011'; then
        __DEFAULT_HL_DEVICE="gaudi"
    elif echo $__pcidev | grep -qE '1020|1030'; then
        __DEFAULT_HL_DEVICE="gaudi2"
    elif echo $__pcidev | grep -qE '106[0-9]'; then
        __DEFAULT_HL_DEVICE="gaudi3"
    fi
    export HL_DEVICE=$__DEFAULT_HL_DEVICE

BKM source

If you visit Habana Gaudi "Upgrade Driver and Software" docs, download mentioned script:

https://vault.habana.ai/artifactory/gaudi-installer/1.21.4/habanalabs-installer.sh

Then, on lines 376 you can find the mentioned function that detects gaudi model version.

Hi @kkurzacz-intel . If there are multiple Gaudi devices installed in the system, this script will identify them all with the same microarchitecture. Is it guaranteed that all Gaudi devices in a system will have the same microarchitecture?

@kkurzacz-intel You can download a dev build here: https://github.com/intel/PerfSpect/actions/runs/17330330318. As I don't have access to Gaudi, please let me know if it works.

I contacted Habana team and they mentioned it's theoretically possible, but very unlikely to happen. For most cases, uniform Gaudi modules are mounted

  "Gaudi": [
    {
      "Bus ID": "0000:4d:00.0",
      "CPLD": "0x0000000F.644A7EDA",
      "Driver Version": "1.21.3-f063886",
      "EROM": "",
      "Microarchitecture": "gaudi2",
      "Module ID": "0",
      "NUMA": "0",
      "SPI": "1.20.1-fw-58.2.6",
      "Serial Number": "AN38031729"
    },

I can confirm on Gaudi 2 it works like a charm, thank you!
