Linux：我如何知道导出设备节点的模块

Linux模块导出设备节点的识别方法

bash
lsmod | grep your_device_module

python
def find_module_for_device(device_name):
    with open('/proc/modules', 'r') as f:
        for line in f:
            module_name, _ = line.split()[:2]
            if module_name:
                module_path = f'/sys/module/{module_name}/devices'
                if os.path.exists(module_path):
                    devices = os.listdir(module_path)
                    if device_name in devices:
                        return module_name
    return None
device_name_to_find = 'your_device_name'
module_found = find_module_for_device(device_name_to_find)
if module_found:
    print(f'Module for device {device_name_to_find}: {module_found}')
else:
    print(f'Module for device {device_name_to_find} not found.')
