Installation

Warning Firstly, we do not support Python 2 – the only support provided is for Python 3.9 and greater.
So please ensure you have Python 3.9 or greater installed.

In order to install OCSysInfo, you can either download the repository manually via GitHub, or via Git.
Then, run the main.py script located in the project's root. (Do also make sure to install the dependencies as shown below.)

# Clone the repository using Git
git clone https://github.com/KernelWanderers/OCSysInfo.git

# Switch to the repository folder
cd OCSysInfo

# Install dependencies
python3 -m pip install -r requirements.txt

# Run the script
python3 main.py

Implementations

OCSysInfo takes advantage of each platform's native interaction protocol, except for Linux, which uses a pseudo file system & its distros expose no consistent way of obtaining this information via command/API, in order to extract information about the system's hardware manually.

Windows

• WMI

  • Windows's WMI (Windows Management Instrumentation) is a protocol allowing us to obtain the current system's data—which is practically anything that we could ever ask for. (Some PCI devices even construct the PCIROOT path where available! Though, generally this data isn't reliable). Data that we look for are as follows (per class):

    • Win32_Processor — information about the current system's CPU in use. Though, we only seek out the following properties:
      • Manufacturer
      • Name
      • NumberOfCores
      • NumberOfLogicalProcessors
    
    

    • Win32_VideoController — information about the current system's GPU devices in use. The only properties we seek out are Name (the GPU's friendly name) and PNPDeviceID, which is basically its PCI path; it includes the device id and vendor id, which we extract.

    • Win32_NetworkAdapter — information about [...] system's Network controllers available. We only want the PNPDeviceID property, from which we can extract the device/vendor id, which we use to query devicehunt.com and pci-ids.ucw.cz if nothing was found in devicehunt.com; the application does not push the device if it cannot be found on either site.

    • Win32_SoundDevice — information about [...] system's audio I/O controllers available. As with the network adapter, we only care about PNPDeviceID.

    • Win32_BaseBoard — information about [...] system's motherboard, we only care about the Product (motherboard model) and Manufacturer (vendor name) properties.

    • Win32_Keyboard — information about [...] system's keyboard(s), their connection types, and possibly their display names. We only look for the Description (type of connector + display name), and the DeviceID property.

    • Win32_PointingDevice — same as the one item before, but instead for mice/trackpads/touchpads/etc.

macOS

• sysctl

  • macOS's sysctl command exposes a way for us to obtain information about the CPU with ease. The key features of this, which we need, are:

    • CPU model
    • CPU instruction flags
    • Core count
    • Thread count
    • Maximum supported SSE version
    • SSSE3 support

• IOKit

  • Apple's IOKit framework allows us to interact with the system's devices (we only seek out IOPCIDevice and IOHDACodecDevice, as more information would be overtly useless to us.)

  • We filter by using IOPCIClassMatch, which can serve as a bit mask match, where the goal is to match the type of device exposed through class-code (i.e. display controllers will generally have a bit that's equal to 0x03, multimedia controllers have a bit that's equal to 0x04, etc.)

  • With IOPCIDevice, we're looking for PCI devices which have a specific bit mask, and we obtain the model (if exposed), device ID and vendor ID through there.

  • With IOHDACodecDevice, we simply seek out built-in audio controllers that have an HDA codec present. If nothing, that suffices our criteria, is returned, we simply look into 0x04 (bit for PCI multimedia controllers.)

  • With IODeviceTree, we're looking for Memory (RAM) modules, which is surprisingly easily obtainable. More-so, we extract the data in the following manner:

    • Instantiate a list which will hold an N amount of dictionaries.
    • Afterwards, loop over each property of the data returned, and convert the values into types we can handle internally (i.e. bytes -> str), and look for the following:

      • dimm-part-number — holds a list of each module's part number (yes, each part number is enumerated uniquely for each memory module)

      • dimm-types — holds a list of each module's DIMM type (DDR3, DDR4, etc.)

      • slot-names — holds a list of each module's BANK and Channel location, as well as the index of that specific channel.

      • dimm-speeds — holds a list of each module's current frequency (as far as we can tell, there's no way of determining the base clock frequency.)

      • reg — holds a byte sequence, from which we determine the capacity of each memory module.

        • Example: 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 -> [1, 1, 1, 1]

        • We then multiply each value from the list with 0x010000 (65536 in decimal), and divide the result by 0x10 (16 in decimal) to calculate the capacity. Here, in our aforementioned example, 1 * 0x010000 / 0x10 would be equal to 4096 (0x1000 in hexadecimal), which is, of course 4096MB.

Linux

• sysfs

  • Devices enumerated as drm (/sys/class/drm) devices are taken into account with the identity of a GPU; which are looked at if cardX directories are found. The directories of these enumerations will generally contain a cardX/device/device and cardX/device/vendor file.

  • Devices enumerated inside of /sys/class/net are classified only if they contain a */device/device and */device/vendor file (so that we can at least have a strong assumption that it'd be a valid network controller.)

  • Devices enumerated inside of /sys/class/sound are looked at for the audio controllers — generally, they'll have a relatively similar enumerations as drm devices — as a cardX format.

• proc

  • We are able to take advantage of what is enumerated and the type of data available in Linux's procfs pseudo filesystem. For example, we may look into /proc/bus/input/devices to list all the names and paths of each input device, and of course, its location in sysfs — which is of use for us.

  • We may also find /proc/cpuinfo, which holds data about the current system's CPU. Though, generally, thread count isn't explicitly stated as is, but rather, each thread has its own set of data enumerated in cpuinfo's dump, so we may simply get the thread count by doing: <cpuinfo>.count('processor')
