The plug-in sets the auto suspend timeout for audio codecs to the value specified by the [option]`timeout` option. Currently, the `snd_hda_intel` and `snd_ac97_codec` codecs are supported and the [option]`timeout` value is in seconds. To disable auto suspend for these codecs, set the [option]`timeout` value to `0`. To enforce the controller reset, set the option [option]`reset_controller` to `true`. Note that power management is supported per module. Hence, the kernel module names are used as device names. .Set the timeout value to 10s and enforce the controller reset ==== ---- [audio] timeout=10 reset_controller=true ---- ==== c � � d| _ t � | _ t � | _ | j j d� j d� D ]3 }| j |� }|dv s�| j j |� �5 y )NT�soundzcard*)� snd_hda_intel�snd_ac97_codec) �_devices_supported�set�_assigned_devices� _free_devices�_hardware_inventory� get_devices�match_sys_name�_device_module_name�add)�self�device� module_names �?/usr/lib/python3.12/site-packages/tuned/plugins/plugin_audio.py� _init_deviceszAudioPlugin._init_devices& sr � � �$�� �5�$���u�$���(�(�4�4�W�=�L�L�W�U�f��)�)�&�1�;��8�8������;�'� V� c � � d|_ d|_ y )NTF)�_has_static_tuning�_has_dynamic_tuning�r �instances r �_instance_initzAudioPlugin._instance_init0 s � � $�(� �!&�(� r c � � y �N� r s r �_instance_cleanupz AudioPlugin._instance_cleanup4 s � �r c �> � |j j S # Y y xY wr# )�parent�driver�r r s r r z AudioPlugin._device_module_name7 s! � �� �-�-� � � ��� �s � � c � � ddd�S )Nr T)�timeout�reset_controllerr$ )�clss r �_get_config_optionsz AudioPlugin._get_config_options= s � � �� � r c � � d|z S )Nz$/sys/module/%s/parameters/power_saver$ r) s r � _timeout_pathzAudioPlugin._timeout_pathD s � � /�&� 8�8r c � � d|z S )Nz//sys/module/%s/parameters/power_save_controllerr$ r) s r �_reset_controller_pathz"AudioPlugin._reset_controller_pathG s � � :�V� C�Cr r+ T)� per_devicec � � t |� }|dk\ rC| j |� }|s.t j |d|z |rt j gnd�� |S y # t $ r t j d|z � Y y w xY w)Nz!timeout value '%s' is not integerr z%dF��no_error) �int� ValueError�log�errorr0 �cmd� write_to_file�errno�ENOENT)r �valuer r �sim�remover+ �sys_files r � _set_timeoutzAudioPlugin._set_timeoutJ s� � �� ��Z�7� ��\�� � ��(�8� ����h��w��"(�� � ��e� � 5� �>� �� � ��9�9� 0�5� 8�9� ��s � A �!A:�9A:c �t � | j |� }t j ||�� }t |� dkD r|S y )Nr5 r )r0 r; � read_file�len�r r r �ignore_missingrB r? s r � _get_timeoutzAudioPlugin._get_timeoutZ s7 � � � � �� '�(� �-�-��>�-� :�%���Z�!�^� �<� r r, c �� � t j |� }| j |� }t j j |� r/|s+t j |||rt j gnd�� |S y )NFr5 ) r; �get_boolr2 �os�path�existsr< r= r> )r r? r r r@ rA �vrB s r �_set_reset_controllerz!AudioPlugin._set_reset_controllerb s_ � � �l�l�5��!� � (� (�� 0�(��W�W�^�^�H� � ����h��"(�� � ��e� � 5� �8� r c �� � | j |� }t j j |� r8t j |� }t |� dkD rt j |� S y )Nr )r2 rL rM rN r; rE rF rK rG s r �_get_reset_controllerz!AudioPlugin._get_reset_controllerm sM � � � (� (�� 0�(��W�W�^�^�H� � �=�=�� "�5� �%�j�1�n� �<�<�� � � r N)F)�__name__� __module__� __qualname__�__doc__r r! r% r � classmethodr. r0 r2 � command_setrC � command_getrI rP rR r$ r r r r s� � ��.(�'��� �� �� 9�D� �i�d�+� � ,� � �i��� �� � �t�4�� 5�� � �!�� "�r r )� r � decorators� tuned.logs�tuned�tuned.utils.commandsr rL r= �struct�glob�logs�getr9 r; �Pluginr r$ r r �<module>rd sF �� � � � )� � � � � �j�j�n�n����j��f�'�.�.� fr
