如果您使用 prink() 打印内核消息并在控制台中读取它,它看起来像这样:
<6>[ 2809.666228] amp_enable: amp enable bypass(2)
<6>[ 2809.666747] amp_enable: AMP_EN is set to 0
<3>[ 2810.084296] init: untracked pid 4196 exited

<6>[ 2810.933923] msm_ta_detect_work: USB exit ta detection - frindex
<6>[ 2817.483839] amp_enable: AMP_EN is set to 1
<6>[ 2823.084022] adjust_soc: ibat_ua = -114500, vbat_uv = 4296066, soc = 95, batt_temp=302

<6>[ 2823.685578] amp_enable: amp enable bypass(2)
<6>[ 2823.686372] amp_enable: AMP_EN is set to 0
每行开头的数字是什么意思?它是某种时间戳吗?我如何解释它?
