Linux 如何在编译中设置内核打印级别
我想知道如何在编译中设置内核打印级别 这意味着不通过向/proc/sys/kernel/printk回显值 这应该很容易，我只是找不到如何Linux 如何在编译中设置内核打印级别,linux,kernel,Linux,Kernel,我想知道如何在编译中设置内核打印级别 这意味着不通过向/proc/sys/kernel/printk回显值 这应该很容易，我只是找不到如何 提前谢谢大家 要设置默认的内核printk级别，无需再次编译到内核 级别是基于内核命令行参数loglevel 从内核文档中： loglevel= All Kernel Messages with a loglevel smaller than the console loglevel will be printed to the cons

loglevelloglevel= All Kernel Messages with a loglevel smaller than the
console loglevel will be printed to the console. It can
also be changed with klogd or other programs. The
loglevels are defined as follows:
0 (KERN_EMERG) system is unusable
1 (KERN_ALERT) action must be taken immediately
2 (KERN_CRIT) critical conditions
3 (KERN_ERR) error conditions
4 (KERN_WARNING) warning conditions
5 (KERN_NOTICE) normal but significant condition
6 (KERN_INFO) informational
7 (KERN_DEBUG) debug-level messages
