    "id": 0,
    "method": "initialize",
    "params": {
        "initializationOptions": {
            "configuration": {
                "buildOptions": [],
                "deviceID": 0,
                "maxNumberOfProblems": 127
            }
        }
    }
}

Options

buildOptions	Options to be utilized when building the program. The list of supported build options.
deviceID	Device ID or 0 (automatic selection) of the OpenCL device to be used for diagnostics.
	Run ./opencl-language-server clinfo to get information about available OpenCL devices including identifiers.
