This plug-in can set parameters to kernel modules. 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|i |�� d| _t� | _d S )NT)�superr �__init__Z_has_dynamic_optionsr �_cmd)�self�args�kwargs�� __class__� �@/usr/lib/python3.9/site-packages/tuned/plugins/plugin_modules.pyr 3 s zModulesPlugin.__init__c C s d|_ d|_|j|_d S )NFT)Z_has_dynamic_tuningZ_has_static_tuning�options�_modules�r �instancer r r �_instance_init8 s z ModulesPlugin._instance_initc C s d S �Nr r r r r �_instance_cleanup= s z ModulesPlugin._instance_cleanupc C s� |D ]�}| j �dd|g�\}}|dk r6t�d� d S |dkrTt�d||�� f � | j �d|g�\}}|dkrt�d||�� f � qd S )NZmodprobez-rr zN'modprobe' command not found, cannot reload kernel modules, reboot is requiredz$cannot remove kernel module '%s': %sz:cannot insert/reinsert module '%s', reboot is required: %s)r �execute�log�warning�debug�strip)r �modules�module�retcode�outr r r �_reload_modules@ s z ModulesPlugin._reload_modulesc C sN | � � d}d}d}g }t|j�� �D ]�\}}| j�|�}| j�|�} |s�| j�d|g�\}} |dk rvd}t� d� n|dkr�t� d| � |s�|dkr&t | �dkr�| dd � d kr�t � d d| �} |�|� t | �dkr�|d | d | d 7 }q&t�d| � q&| j�tj|� t |�} | dk�rJ| �|� t |j�| k�rJt�tj� d S )N� r FZmodinfoTz8'modinfo' command not found, not checking kernel modulesz)kernel module '%s' not found, skipping itr � z+r�^\s*\+r\s*,?\s*zoptions � � zKmodule '%s' doesn't have any option specified, not writing it to modprobe.d)�_clear_modprobe_file�listr �items� _variables�expandr r r r �error�len�re�sub�appendr � write_to_file�consts� MODULES_FILEr! �infoZSTR_HINT_REBOOT) r r �sr Z skip_checkZ reload_list�option�valuer �vr �lr r r �_instance_apply_staticL s8 z$ModulesPlugin._instance_apply_staticc C s t |��dd�S )N�/r" )�str�replace)r �pathr r r � _unquote_pathk s zModulesPlugin._unquote_pathc C s d}d}t �d�}t|j�� �D ]�\}}| j�|�}| j�|�} t �dd| �} d| } tj � | �s|d}t � t jd | � q t �t jd | � |�| �} | D ]p} | �d d �} t| �d kr�t �d || f � q�| �| d | d | jj| d | �| d � d dd�|�dkr�d}q�q |S )NTz\s+r$ r" z/sys/module/%sFzmodule '%s' is not loadedzmodule '%s' is loaded�=r r# z.unrecognized module option for module '%s': %sr z /parameters/)Zerr_ret�no_error)r. �compiler( r r) r* r+ r/ �osr> �existsr r, r2 ZSTR_VERIFY_PROFILE_FAILr4 ZSTR_VERIFY_PROFILE_OK�splitr- r Z _verify_valuer � read_filer? )r r Zignore_missingZdevices�ret�rr6 r7 r r8 Zmpathr9 �item�argr r r �_instance_verify_staticn s2 "��z%ModulesPlugin._instance_verify_staticc C s |t jkr| �� d S r )r2 Z ROLLBACK_FULLr' )r r Zrollbackr r r �_instance_unapply_static� s z&ModulesPlugin._instance_unapply_staticc C s� | j jtjdd�}|�d�}d }}t|�}t�d�}||k rb|�|| �d u rX|}|}|d7 }q6d� |d|� �}t|�dkr�|d7 }| j � tj|� d S )NT)rA r& r z^\s*#r ) r rF r2 r3 rE r- r. rB �search�joinr1 )r r5 r9 �i�jZllrH r r r r' � s z"ModulesPlugin._clear_modprobe_file)�__name__� __module__� __qualname__�__doc__r r r r! r: r? rK r2 Z ROLLBACK_SOFTrL r' � __classcell__r r r r r s & r )r.
