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 C sP d| _ t� | _t� | _| j�d��d�D ]"}| �|�}|dv r(| j�|� q(d S )NTZsoundzcard*)Z snd_hda_intelZsnd_ac97_codec) Z_devices_supported�setZ_assigned_devicesZ _free_devicesZ_hardware_inventoryZ get_devicesZmatch_sys_name�_device_module_name�add)�self�deviceZ module_name� r �>/usr/lib/python3.9/site-packages/tuned/plugins/plugin_audio.py� _init_devices& s zAudioPlugin._init_devicesc C s d|_ d|_d S )NTF)Z_has_static_tuningZ_has_dynamic_tuning�r �instancer r r �_instance_init0 s zAudioPlugin._instance_initc C s d S �Nr r r r r �_instance_cleanup4 s z AudioPlugin._instance_cleanupc C s z |j jW S Y d S 0 d S r )�parentZdriver�r r r r r r 7 s z AudioPlugin._device_module_namec C s ddd�S )Nr T)�timeout�reset_controllerr )�clsr r r �_get_config_options= s �z AudioPlugin._get_config_optionsc C s d| S )Nz$/sys/module/%s/parameters/power_saver r r r r � _timeout_pathD s zAudioPlugin._timeout_pathc C s d| S )Nz//sys/module/%s/parameters/power_save_controllerr r r r r �_reset_controller_pathG s z"AudioPlugin._reset_controller_pathr T)Z per_devicec C sr z t |�}W n" ty. t�d| � Y d S 0 |dkrj| �|�}|sftj|d| |r^tjgndd� |S d S d S )Nz!timeout value '%s' is not integerr z%dF�Zno_error) �int� ValueError�log�errorr �cmd� write_to_file�errno�ENOENT)r �valuer r �sim�remover �sys_filer r r � _set_timeoutJ s �zAudioPlugin._set_timeoutFc C s, | � |�}tj||d�}t|�dkr(|S d S )Nr r )r r! � read_file�len�r r r Zignore_missingr( r% r r r � _get_timeoutZ s zAudioPlugin._get_timeoutr c C sH t �|�}| �|�}tj�|�rD|s@t j|||r8tjgndd� |S d S )NFr ) r! �get_boolr �os�path�existsr" r# r$ )r r% r r r& r' �vr( r r r �_set_reset_controllerb s �z!AudioPlugin._set_reset_controllerc C s: | � |�}tj�|�r6t�|�}t|�dkr6t�|�S d S )Nr )r r/ r0 r1 r! r* r+ r. r, r r r �_get_reset_controllerm s z!AudioPlugin._get_reset_controllerN)F)F)�__name__� __module__� __qualname__�__doc__r r r r � classmethodr r r Z command_setr) Z command_getr- r3 r4 r r r r r s" r )� r Z decoratorsZ tuned.logsZtunedZtuned.utils.commandsr r/ r# �struct�globZlogs�getr r!
