dev_info() 启动过程、或者模块加载过程等“通知类的”信息等,一般只会通知一次,例如probe函数 dev_dbg() 一般使用在普通错误,如-EINVAL、-ENOMEM等errno发生处,用于调试 dev_err() 一般使用在严重错误,尤其是用户无法得到errno的地方,或者程序员不容易猜测系统哪里出了问题的地方 打印dev_dbg# A dynamic_debug#...
2 dev_err/dev_info/dev_warn 在Linux驱动代码中,有大量的调试信息,那么推荐使用dev_err/dev_info/dev_warn这一系列函数族。这一系列函数族定义在include/linux/device.h。 其实这些函数族本质上和下面printk.h中的定义也是完全一致的。 #definepr_emerg(fmt, ...) \ printk(KERN_EMERG pr_fmt(fmt), ##...
