2.1 kobject内核对象 Kobject 是Linux 2.6引入的新的设备管理机制,在内核中由struct kobject表示。通过这个数据结构使所有设备在底层都具有统一的接口,kobject提供基本的对象管理,是构成Linux 2.6设备模型的核心结构,它与sysfs文件系统紧密关联,每个在内核中注册的kobject对象都对应于sysfs文件系统中的一个目录。 Kobjec...
在内核中启用 SELinux:CONFIG_SECURITY_SELINUX=y 更改kernel_cmdline 或 bootconfig 参数,以便: BOARD_KERNEL_CMDLINE := androidboot.selinux=permissive 或 BOARD_BOOTCONFIG := androidboot.selinux=permissive 这仅适用于初始制定设备政策的情况。在拥有初始引导程序政策后,请移除此参数,以便将设备恢复强制模式,否...
但是如果非要回答它的话,我们可以回答说是linux内核的“核”是如何保证一个操作系统最基本的功能的问题的解(核)。 但是其实linux内核就是linux操作系统中最基础最关键的部分的,如果非要把linux内核和某个具体的问题联系起来,认为它是这个具体的问题的解,其实是没有必要的。 所以我们对核的定义,也不在限制它必须是...
# cat /proc/sys/kernel/watchdog_thresh 10 所以,缺省情况下,softlockup的判定时长是大于20秒。 测试代码如下: #include<linux/kernel.h> #include<linux/module.h> #include<linux/kthread.h> #include <linux/delay.h> #include <linux/sched/clock.h> #include <linux/jiffies.h> #include <linux/s...

进入你的 project 进入ios 目录 点击 xxx.xcodeproj command + r Port 8081 already in use, packager is either not running or not running correctly(8081端口被占用) 那就查看谁暂用了这个端口 执行下面命令 lsof -i tcp:8081 发现快播播放暂用了这个端口,关闭快播在...My...

Actual Behavior While trying to use the docker-compose that comes with rancher-desktop I get the following failure message: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap. S...
When UART0 is used instead of UART1 in a Zynq-based system, the Linux kernel does not boot. Solution This is caused by PetaLinux not updating the debug interface in the kernel configuration to use UART0 instead of UART1. There are two possible solutions:1) Remove earlyprintk from the Lin...
