在linux的源代码中,有这样的一个文档Documentation/kernel-parameters.txt,它介绍了kernel的各个参数及其意义。 其次,kernel启动参数以空格分隔,而且是严格区分大小写的(如:mem和MEM是不一样的)。 再次,对于module特有的kernel参数写法是这样的,[module name].[parameter=XX],例如,igb.max_vfs=7这个kernel启动参数的...

This parameter enables that. enable_timer_pin_1 [X86] Enable PIN 1 of APIC timer Can be useful to work around chipset bugs (in particular on some ATI chipsets). The kernel tries to set a reasonable default. enforcing [SELINUX] Set initial enforcing status. Format: {"0" | "1"} See ...

Modify the kernel parameters only if the parameter settings affect your services. Kernel parameters vary depending on OS versions. If the parameter settings must be modif

be used to create a new connection without waiting 2MSL time. In the NAT environment, turning on the tcp\_tw\_recycle parameter will trigger the PAWS mechanism and cause packet loss. It is recommended not to enable it. In fact, the kernel is in version 4.1 Then delete this parameter. ...
In Linux kernel version 4.12 and later, the net.ipv4.tcp_tw_recycle parameter is removed from the sysctl.conf file. Thenet.ipv4.tcp_tw_recycleparameter can be configured only in kernel versions earlier than 4.12. View and modify kernel parameters by using the file in the /proc/sy...
