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 ---- ==== cCsTd|_t�|_t�|_x8|jjd�jd�D]"}|j|�}|dkr*|jj|�q*WdS)NTZsoundzcard*� snd_hda_intel�snd_ac97_codec)rr) Z_devices_supported�setZ_assigned_devicesZ _free_devicesZ_hardware_inventoryZget_devicesZmatch_sys_name�_device_module_name�add)�self�deviceZmodule_name�r�"/usr/lib/python3.6/plugin_audio.py� _init_devices(s zAudioPlugin._init_devicescCsd|_d|_dS)NTF)Z_has_static_tuningZ_has_dynamic_tuning)r�instancerrr�_instance_init2szAudioPlugin._instance_initcCsdS)Nr)rrrrr�_instance_cleanup6szAudioPlugin._instance_cleanupc Csy|jjSdSdS)N)�parentZdriver)rr rrrr 9szAudioPlugin._device_module_namecCs ddd�S)NrF)�timeout�reset_controllerr)�clsrrr�_get_config_options?szAudioPlugin._get_config_optionscCsd|S)Nz$/sys/module/%s/parameters/power_saver)rr rrr� _timeout_pathFszAudioPlugin._timeout_pathcCsd|S)Nz//sys/module/%s/parameters/power_save_controllerr)rr rrr�_reset_controller_pathIsz"AudioPlugin._reset_controller_pathrT)Z per_devicec Csryt|�}Wn"tk r.tjd|�dSX|dkrj|j|�}|sftj|d||r^tjgndd�|SdSdS)Nz!timeout value '%s' is not integerrz%dF)�no_error) �int� ValueError�log�errorr�cmd� write_to_file�errno�ENOENT)r�valuer �sim�remover�sys_filerrr�_set_timeoutLs zAudioPlugin._set_timeoutFcCs,|j|�}tj||d�}t|�dkr(|SdS)N)rr)rr � read_file�len)rr �ignore_missingr'r$rrr�_get_timeout\s zAudioPlugin._get_timeoutrcCsHtj|�}|j|�}tjj|�rD|s@tj|||r8tjgndd�|SdS)NF)r) r �get_boolr�os�path�existsr!r"r#)rr$r r%r&�vr'rrr�_set_reset_controllerds z!AudioPlugin._set_reset_controllercCs:|j|�}tjj|�r6tj|�}t|�dkr6tj|�SdS)Nr)rr.r/r0r r)r*r-)rr r+r'r$rrr�_get_reset_controlleros z!AudioPlugin._get_reset_controllerN)F)F)�__name__� __module__�__qualname__�__doc__rrrr �classmethodrrrZcommand_setr(Zcommand_getr,r2r3rrrrrs r)�rZ decoratorsZ tuned.logsZtunedZtuned.utils.commandsrr.r"�structZglobZlogs�getrr ZPluginrrrrr�s
