This plug-in is used for applying custom `sysctl` settings and should only be used to change system settings that are not covered by other *TuneD* plug-ins. If the settings are covered by other *TuneD* plug-ins, use those plug-ins instead. The syntax for this plug-in is `_key_=_value_`, where `_key_` is the same as the key name provided by the `sysctl` utility. .Adjusting the kernel runtime kernel.sched_min_granularity_ns value ==== ---- [sysctl] kernel.sched_min_granularity_ns=3000000 ---- ==== 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_sysctl.pyr ) s zSysctlPlugin.__init__c C sh d|_ d|_| �|j�}| j�|i �|_t|j�dkr\t� d� | � |� i |_| j� |� |j |_ d S )NFTr z0recovering old sysctl settings from previous run)Z_has_dynamic_tuningZ_has_static_tuning� _storage_key�name�_storage�get�_sysctl_original�len�log�info�_instance_unapply_static�unset�options�_sysctl�r �instance� storage_keyr r r �_instance_init. s zSysctlPlugin._instance_initc C s | � |j�}| j�|� d S �N)r r r r r r r r �_instance_cleanup> s z SysctlPlugin._instance_cleanupc C s� t |j�� �D ]h\}}| �|�}|d u r8t�d| � q| j�| j� |��}| � ||�}|d ur||j |< | � ||� q| � |j�}| j�||j � | j�tjtj�r�t�d� | �|j� d S )NzDsysctl option %s will not be set, failed to read the original value.zreapplying system sysctl)�listr �items� _read_sysctlr �error� _variables�expandr �unquote� _process_assignment_modifiersr � _write_sysctlr r r �set� _global_cfgZget_bool�constsZCFG_REAPPLY_SYSCTLZCFG_DEF_REAPPLY_SYSCTLr �_apply_system_sysctl)r r �option�value�original_valueZ new_valuer r r r �_instance_apply_staticB s( � �� z#SysctlPlugin._instance_apply_staticc C sr d}d}t |j�� �D ]V\}}| �|�}| �| j�|�|�}|d ur| �|| j� |�| j� |�|�dkrd}q|S )NTF) r# r r$ r% r* r' r( Z _verify_valuer Z remove_ws)r r �ignore_missingZdevices�retr0 r1 Zcurr_valr r r �_instance_verify_staticX s $z$SysctlPlugin._instance_verify_staticc C s( t |j�� �D ]\}}| �||� qd S r! )r# r r$ r+ )r r Zrollbackr0 r1 r r r r d s z%SysctlPlugin._instance_unapply_staticc C s2 | j �tjtj�}|D ]}t�||�r dS qdS )z7Check if a sysctl option matches any exclusion pattern.TF)r- Zget_listr.
