Intentionally a lot of logic is included in the plugin to increase plugin flexibility. c C sn |� | jj�| _|| _|| _|| _|| _|| _t � � | _ | � � || _ || _d| _d| _| �� | _t� | _dS )zPlugin constructor.FN)�create� __class__�__name__�_storageZ_monitors_repositoryZ_hardware_inventory�_device_matcher�_device_matcher_udev�_instance_factory� collections� OrderedDict� _instances�_init_commands� _global_cfg� _variables�_has_dynamic_options�_devices_inited�#_get_config_options_used_by_dynamic�_options_used_by_dynamicr �_cmd) �selfZmonitors_repositoryZstorage_factoryZhardware_inventoryZdevice_matcherZdevice_matcher_udevZinstance_factoryZ global_cfgZ variables� r �6/usr/lib/python3.9/site-packages/tuned/plugins/base.py�__init__ s zPlugin.__init__c C s | � � d S �N)�destroy_instances�r r r r �cleanup, s zPlugin.cleanupc C s | j s| �� d| _ d S )NT)r � _init_devicesr r r r � init_devices/ s zPlugin.init_devicesc C s | j j�d�d �dd�d S )N�.����_� )r � __module__�splitr r r r �name4 s z Plugin.namec C s i S )z-Default configuration options for the plugin.r r r r r �_get_config_options< s zPlugin._get_config_optionsc C s i S )z*Explanation of each config option functionr )�clsr r r �get_config_options_hintsA s z Plugin.get_config_options_hintsc C s g S )znList of config options used by dynamic tuning.
