HWAPI

This API provides a backend for fetching information about hardware.

Current information fetched includes:

  • CPU info (Intel ARK, AMD Product Database)
  • USB info (VID/PID mapping)
  • PCIe info (VID/PID/SUBSYS mapping)
  • Windows BugCheck error codes

Project layout

The code is organized into 4 separate crates:

  • parsing: The code for parsing the raw databases into Rust abstractions.
  • databases: The interfaces for fast lookup from those databases.
  • handlers: The HTTP endpoint code
  • server: The binary and runtime specific details

Building

Building this project requires installing the rust toolchain.

To build the project (development):

cargo build

To run the project (development):

cargo run

This will start a server on port 3000.

To build a release executable:

cargo build --release

The resulting executable will be located in ./target/release/.

Testing

Testing also requires the rust toolchain installed.

To test the project:

cargo test

To profile the project, you'll need cargo flamegraph installed (cargo install flamegraph):

cargo flamegraph --root --unit-test -- [TEST_NAME]

Where [TEST_NAME] is the test you want to profile. There are other ways to profile different parts of the code, but you can figure that out yourself.

Configuration

By default, the application listens on port 3000, although that can be configured by setting the HWAPI_PORT environment variable or by passing -p/--port.

Endpoints

CPU

To interact with the CPU API, submit a GET request to /api/cpus/?name=[CPU_NAME], where [CPU_NAME] is the URL encoded name of the cpu.

This endpoint does not guarantee the correctness of the model returned, it will always attempt to return a model.

Here's an example curl request:

curl "http://localhost:3000/api/cpus/?name=Intel%20Core%20i9-9900k"

USB

To interact with the USB API, submit a GET request to /api/usbs/?identifier=[USB_IDENTIFIER_STRING], where [USB_IDENTIFIER_STRING] is a valid USB identifier.

The endpoint will return a structure that looks like this:

{
    "vendor": "string",
    "device": "string | null",
}

Responses:

Code Meaning
404 No USB info was found with the given identifier

Here's an example curl request:

curl "http://127.0.0.1:3000/api/usbs/?identifier=USB%5CVID_1532%26PID_0084%26MI_03%5C6%2638C0FA5D%260%260003"

For bulk processing, you may submit a POST request to the same endpoint with a Content-Type of application/json and a payload containing an array of USB device identifier strings.

The endpoint will return an array of objects (same shape as the GET request), or if an identifier string was unable to be processed successfully, null will substitute in the response.

Here's an example curl request:

curl -X POST http://127.0.0.1:3000/api/usbs/ -H "Content-Type: application/json" -d '["USB\\\\VID_1038&PID_1729\\\\6&28B2
9415&0&4","USB\\\\VID_413C&PID_2105\\\\6&3B66B33D&0&9","USB\\\\ROOT_HUB30\\\\5&381F2DE&0&0","USB\\\\VID_1038&PID_1729&MI_00\\\\7&381E8103&0&0000","USB\\\\VID_0B05&PID_184C\\\\123456","US
B\\\\VID_1038&PID_1729&MI_01\\\\7&381E8103&0&0001","USB\\\\ROOT_HUB30\\\\5&3B7A03C3&0&0"]'

And here's an example response (truncated):

[
   {
      "vendor":"SteelSeries ApS",
      "device":null
   },
   {
      "vendor":"Dell Computer Corp.",
      "device":"Model L100 Keyboard"
   },
   null
]

PCIe

To interact with the PCIe API, submit a GET request to /api/pcie/?identifier=[PCIE_IDENTIFIER_STRING], where [PCIE_IDENTIFIER_STRING] is a valid PCIe identifier.

The endpoint will return a structure that looks like this:

{
    "vendor": "string",
    "device": "string | null",
    "subsystem": "string | null"
}

Responses:

Code Meaning
404 No PCIe info was found with the given identifier

Here's an example curl request:

curl "http://127.0.0.1:3000/api/pcie/?identifier=PCI%5CVEN_8086%26DEV_7A4D%26SUBSYS_00000000%26REV_11%5C3%2611583659%260%26A9%0A"

For bulk processing, you may submit a POST request to the same endpoint with a Content-Type of application/json and a payload containing an array of PCIe device identifier strings.

The endpoint will return an array of objects (same shape as the GET request), or if an identifier string was unable to be processed successfully, null will substitute in the response.

Here's an example curl request:

curl -X POST http://127.0.0.1:3000/api/pcie/ -H "Content-Type: application/json" -d '["PCI\\\\VEN_1022&DEV_43B4&SUBSYS_33

And here's example response (truncated):

[
   {
      "vendor":"Advanced Micro Devices, Inc. [AMD]",
      "device":"300 Series Chipset PCIe Port",
      "subsystem":null
   },
   {
      "vendor":"Advanced Micro Devices, Inc. [AMD]",
      "device":"Matisse/Vermeer Data Fabric: Device 18h; Function 4",
      "subsystem":null
   },
]

BugCheck

To interact with the bugcheck API, submit a GET request to /api/bugcheck/?code=[BUGCHECK_CODE], where [BUGCHECK_CODE] is an integer value of a valid bugcheck code.

The endpoint will return a structure that looks like this:

{
    "code": "number",
    "name": "string",
    "url": "string",
}

Responses:

Code Meaning
404 No bugcheck is associated with that code

Here's an example curl request:

curl http://127.0.0.1:3000/api/bugcheck/?code=1

For bulk processing, you may submit a POST request to the same endpoint with a Content-Type of application/json and a payload containing an array of bugcheck codes (as numbers).

The endpoint will return an array of objects (same shape as the GET request), or if an identifier string was unable to be processed successfully, null will substitute in the response.

Here's an example curl request:

curl -X POST http://127.0.0.1:3000/api/bugcheck/ -H "Content-Type: application/json" -d '[1, 2, 3, 4, 5]'

And here's an example response (truncated):

      "vendor":"SteelSeries ApS",
      "device":null
   },
   {
      "vendor":"Dell Computer Corp.",
      "device":"Model L100 Keyboard"
   },
   null
