Get Manufacturer (Linux)

Description

The get_manufacturer_linux function retrieves the manufacturer of the system on Linux. It first attempts to get the model information from the /proc/cpuinfo file. If the system is a Raspberry Pi, it returns the parsed model. If the system is not a Raspberry Pi, it falls back to using dmidecode to retrieve the processor's manufacturer. If an error occurs, it returns an empty string and a status code of 1.

Function Signature:

def get_manufacturer_linux() -> tuple[str, int]:

Parameters

This function does not take any parameters.

Returns

• tuple: A tuple containing two values:
  • str: The manufacturer name or model (e.g., "Raspberry Pi", "Intel").
  • int: A status code indicating the result of the operation (e.g., 0 for success, 1 for failure).

Example Usage

Here’s an example of how the function works:

manufacturer, status = get_manufacturer_linux()
print(f"Manufacturer: {manufacturer}, Status: {status}")

Example Output:

Manufacturer: Raspberry Pi, Status: 0

Code

def get_manufacturer_linux() -> tuple[str, int]:
    try:
        with open("/proc/cpuinfo", "r") as f:
            for line in f:
                if line.startswith("Model"):
                    model = line.split(":")[1].strip()
                    if "Raspberry Pi" in model:
                        return parse_raspberry_pi_model(model), 0
        # Fall back to using dmidecode if not a Raspberry Pi
        result = subprocess.run(['dmidecode', '-t', 'processor'], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
        for line in result.stdout.splitlines():
            if line.strip().startswith("Manufacturer"):
                return parse_manufacturer(line.split(":")[1].strip()), 0
    except Exception as e:
        print(f"Exception in get_manufacturer_linux: {e}")
        return "", 1

    return "", 1

Errors and Exceptions

• If an error occurs while querying the /proc/cpuinfo file or running the dmidecode command, an exception is caught, and the function returns an empty string and a failure status code (1).

Notes

This function is platform-specific and is designed to work on Linux systems. It uses the /proc/cpuinfo file and the dmidecode command to fetch details about the system's manufacturer or model. The function also supports identifying Raspberry Pi models.
