It creates `/etc/modprobe.d/tuned.conf` file. The syntax is `_module_=_option1=value1 option2=value2..._` where `_module_` is the module name and `_optionx=valuex_` are module options which may or may not be present. + .Load module `netrom` with module parameter `nr_ndevs=2` ==== ---- [modules] netrom=nr_ndevs=2 ---- ==== Modules can also be forced to load/reload by using an additional `+r` option prefix. + .(Re)load module `netrom` with module parameter `nr_ndevs=2` ==== ---- [modules] netrom=+r nr_ndevs=2 ---- ==== The `+r` switch will also cause *TuneD* to try and remove `netrom` module (if loaded) and try and (re)insert it with the specified parameters. The `+r` can be followed by an optional comma (`+r,`) for better readability. + When using `+r` the module will be loaded immediately by the *TuneD* daemon itself rather than waiting for the OS to load it with the specified parameters. c s$ t t| �j||� d| _t� | _d S )NT)�superr �__init__Z_has_dynamic_optionsr �_cmd)�self�args�kwargs)� __class__� �$/usr/lib/python3.6/plugin_modules.pyr 3 s zModulesPlugin.__init__c C s d|_ d|_|j|_d S )NFT)Z_has_dynamic_tuningZ_has_static_tuningZoptions�_modules)r �instancer r r �_instance_init8 s z ModulesPlugin._instance_initc C s d S )Nr )r r r r r �_instance_cleanup= s z ModulesPlugin._instance_cleanupc C s� x�|D ]�}| j jdd|g�\}}|dk r6tjd� d S |dkrTtjd||j� f � | j jd|g�\}}|dkrtjd||j� f � qW d S )NZmodprobez-rr zN'modprobe' command not found, cannot reload kernel modules, reboot is requiredz$cannot remove kernel module '%s': %sz:cannot insert/reinsert module '%s', reboot is required: %s)r �execute�log�warn�debug�strip)r �modules�module�retcode�outr r r �_reload_modules@ s z ModulesPlugin._reload_modulesc C sR | j � d}d}d}g }x�t|jj� �D ]�\}}| jj|�}| jj|�} |s�| jjd|g�\}} |dk rxd}tj d� n|dkr�tj d| � |s�|dkr(t | �dkr�| dd � d kr�t j d d| �} |j|� t | �dkr�|d | d | d 7 }q(tjd| � q(W | jjtj|� t |�} | dk�rN| j|� t |j�| k�rNtjtj� d S )N� r FZmodinfoTz8'modinfo' command not found, not checking kernel modulesz)kernel module '%s' not found, skipping itr � z+rz^\s*\+r\s*,?\s*zoptions � � zKmodule '%s' doesn't have any option specified, not writing it to modprobe.d)�_clear_modprobe_file�listr �items� _variables�expandr r r r �error�len�re�sub�appendr � write_to_file�consts� MODULES_FILEr �infoZSTR_HINT_REBOOT) r r �sr Z skip_checkZ reload_list�option�valuer �vr �lr r r �_instance_apply_staticL s8 z$ModulesPlugin._instance_apply_staticc C s t |�jdd�S )N�/r )�str�replace)r �pathr r r � _unquote_pathk s zModulesPlugin._unquote_pathc C s d}d}t jd�}�xt|jj� �D ]�\}}| jj|�}| jj|�} t jdd| �} d| } tj j | �s�d}t j t jd | � q$t jt jd | � |j| �} xv| D ]n} | jd �} t| �d kr�t jd || f � q�| j| d | d | jj| d | j| d � d dd�|�dkr�d}q�W q$W |S )NTz\s+z^\s*\+r\s*,?\s*r z/sys/module/%sFzmodule '%s' is not loadedzmodule '%s' is loaded�=r z.unrecognized module option for module '%s': %sr r z /parameters/)Zerr_ret�no_error)r) �compiler# r r$ r% r& r* �osr9 �existsr r' r- ZSTR_VERIFY_PROFILE_FAILr/ ZSTR_VERIFY_PROFILE_OK�splitr( r Z _verify_valuer � read_filer: )r r Zignore_missingZdevices�ret�rr1 r2 r r3 Zmpathr4 �item�argr r r �_instance_verify_staticn s, " z%ModulesPlugin._instance_verify_staticc C s |t jkr| j� d S )N)r- Z ROLLBACK_FULLr" )r r Zrollbackr r r �_instance_unapply_static� s z&ModulesPlugin._instance_unapply_staticc C s� | j jtjdd�}|jd�}d }}t|�}tjd�}x.||k rd|j|| �d krZ|}|}|d7 }q8W dj |d|� �}t|�dkr�|d7 }| j j tj|� d S )NT)r< r! r z^\s*#r ) r rA r- r. r@ r( r) r= �search�joinr, )r r0 r4 �i�jZllrC r r r r" � s z"ModulesPlugin._clear_modprobe_file)�__name__� __module__� __qualname__�__doc__r r r r r5 r: rF r- Z ROLLBACK_SOFTrG r" � __classcell__r r )r r r s % r )r) Zos.pathr> r r Z decoratorsZ tuned.logsZtuned� subprocessZtuned.utils.commandsr Z tuned.constsr- Zlogs�getr ZPluginr r r r r �<module> s
